PARIS wears her greenest livery and puts on her most gracious airs in early summer. When the National Fete commemorative of the Bastille’s fall has gone, there are few Parisians of wealth or leisure who remain in their city. Trouville, Deauville, Etretat and other pleasure cities claim them and even the bourgeoisie hie them to their summer villas.

The city is given up to those tourists from America and England whom Paris still persists in calling Les Cooks in memory of that enterprising blazer of cheap trails for the masses. Your true Parisian and the stranger who has stayed within the city’s gates to know her well, find themselves wholly out of sympathy with the eager crowds who follow beaten tracks and absorb topographical knowledge from guide-books.

Monty Vaughan was an American who knew his Paris in all months but those two which are sacred to foreign travelers, and it irritated him one blazing afternoon in late July to be persistently mistaken for a tourist and offered silly useless toys and plans of the Louvre. The camelots, those shrewd itinerant merchants of the Boulevards, pestered him continually. These excellent judges of human nature saw in him one who lacked the necessary harshness to drive them away and made capital of his good nature.

He was a slim, pleasant-looking man of five and twenty, to whom the good things of this world had been vouchsafed, with no effort on his part to obtain them; and in spite of this he preserved a certain frank and boyish charm which had made him popular all his life.

Presently on his somewhat aimless wanderings he came down the Avenue de l’Opéra and took a seat under the awning and ordered an innocuous drink. He was in a city where he had innumerable friends, but they had all left for the seashore and this loneliness was unpleasant to his friendly spirit. But even in the Café de Paris he was not to be left alone and he was regarded as fair game by alert hawkers. One would steal up to his table and deposit a little measure of olives and plead for two sous in exchange. Another would place some nuts by his side and demand a like amount. And when they had been driven forth and he had lighted a cigarette, he observed watching him with professional eagerness a ramasseur de megot, one of those men who make a livelihood of picking up the butts of cigars and cigarettes and selling them.

When Monty flung down the half-smoked cigarette in hope that the man would go away he was annoyed to find that the fellow was congratulating himself that here was a tourist worth following, who smoked not the wispy attenuated cigarettes of the native but one worth harvesting. He probed for it with his long stick under the table and stood waiting for another.

The heat, the absence of his friends and the knowledge that he must presently dine alone had brought the usually placid Monty into a wholly foreign frame of mind and he rose abruptly and stalked down the Avenue.

A depressed-looking sandwich-man, bearing a device which read, “One can laugh uproariously at the Champs Elysées every night during the summer months,” blocked his way, and permitted a woman selling fans of the kind known to the camelots as les petits vents du nord to thrust one upon him. “Monsieur does not comprehend our heat in Paris,” she said. “Buy a little north wind. Two sous for a little north wind.”

Monty thrust a franc in her hand and turned quickly from her to carom against a tall well-dressed man who was passing. As Monty began to utter his apology the look of gloom dropped from his face and he seized the stranger’s hand and shook it heartily.

“Steve, old man!” he cried, “what luck to find you amid this mob! I’ve been feeling like a poor shipwrecked orphan, and here you come to my rescue again.”

The man he addressed as Steve seemed just as pleased to behold Monty Vaughan. The two were old comrades from the days at their preparatory school and had met little during the past five years. Monty’s ecstatic welcome was a pleasant reminder of happy days that were gone.

“I might ask what you are doing here,” Steven Denby returned. “I imagined you to be sunning yourself in Newport or Bar Harbor, not doing Paris in July.”

“I’ve been living here for two years,” Monty explained, when they were sheltered from interruption at the café Monty had just left.

“Doing what?”

Monty looked at him with a diffident smile. “I suppose you’ll grin just like everybody else. I’m here to learn foreign banking systems. My father says it will do me good.”

Denby laughed. “I’ll bet you know less about it than I do.” The idea of Monty Vaughan, heir to the Vaughan millions, working like a clerk in the Crédit Lyonnais was amusing.

“Does your father make you work all summer?” he demanded.

“I’m not working now,” Monty explained. “I never do unless I feel like it. I’m waiting for a friend who is sailing with me on the Mauretania next week and I’ve just had a wire to say she’ll be here to-morrow.”

“She!” echoed Denby. “Have you married without my knowledge or consent? Or is this a honey-moon trip you are taking?”

A look of sadness came into the younger man’s face.

“I shall never marry,” he returned.

But Steven Denby knew him too well to take such expressions of gloom as final. “Nonsense,” he cried. “You are just the sort they like. You’re inclined to believe in people too much if you like them, and a husband who believes in his wife as you will in yours is a treasure. They’ll fight for you, Monty, when you get home again. For all you know the trap is already baited.”

“Trap!” Monty cried reproachfully. “I’ve been trying to make a girl catch me for three years now and she won’t.”

“Do you mean you’ve been finally turned down?” Steven Denby asked curiously. It was difficult to suppose that a man of his friend’s wealth and standing would experience much trouble in offering heart and fortune.

“I haven’t asked yet,” Monty admitted. “I’ve been on the verge of it hundreds of times, but she always laughs as I’m coming around to it, and someone comes in or something happens and I’ve never done it.” He sighed with the deprecating manner of the devout lover. “If you’d only seen her, Steve, you’d see what mighty little chance I stood. I feel it’s a bit of impertinence to ask a girl like that to marry me.”

Steven patted him on the arm. “You’re just the same,” he said, “exactly the silly old Monty I used to know. Next time you see your charmer, risk being impertinent and ask her to marry you. Women hate modesty nowadays. It’s just a confession of failure and we’re all hitched up to success. I don’t know the girl you are speaking of but when you get home again instead of declaring your great unworthiness, tell her you’ve left Paris and its pleasures simply to marry her. Say that the Bourse begged you to remain and guide the nation through a financial panic, but you left them weeping and flew back on a fast Cunarder.”

“I believe you are right,” Monty said. “I’ll do it. I ought to have done it years ago. Alice is frightfully disappointed with me.”

“Who is Alice?” the other demanded. “The lady you’re crossing with on the Mauretania?”

“Yes,” said Monty. “A good pal of mine; one of those up-to-date women of the world who know what to do and say at the right moment. She’s a sort of elder sister to me. You’ll like her, Steve.”

Denby doubted it but pursued the subject no further. He conceived Alice to be one of those capable managing women who do so much good in the world and give so little pleasure.

“What are you doing in Paris now?” Monty presently demanded. It occurred to him that it was odd that Denby, too, should be in the city now.

“Writing a book on the Race Courses of the World,” he said, smiling. “I am now in the midst of Longchamps.”

Monty looked at him doubtfully. He had never known that his friend had any literary aspirations, but he did remember him as one who, if he did not choose to tell, would invent airy fairy fancies to deceive.

“I don’t believe it,” he said.

“You are quite right,” Denby admitted. “You’ve got the key to the mystery. I’ll confess that I have been engaged to guard Mona Lisa. Suspicious looking tourists such as you engage my special attention. Don’t get offended, Monty,” he added, “I’m just wandering through the city on my way to England and that’s the truth, simple as it may seem. I was desolate and your pleasing countenance as you bought a franc’s worth of north wind was good to see. I wondered if you’d remember me.”

“Remember you!” Monty snorted. “Am I the kind to forget a man who saved my life?”

“Who did that?” Denby inquired.

“Why, you did,” he returned, “You pulled me out of the Nashua river at school!”

The other man laughed. “Why, it wasn’t five feet deep there.”

“I can drown anywhere,” Monty returned firmly. “You saved my life and I’ve never had the opportunity to do anything in return.”

“The time will come,” Denby said lightly. “You’ll get a mysterious message sometime and it will be up to you to rescue me from dreadful danger.”

“I’d like to,” the other retorted, “but I’m not sure I’m cut out for that rescue business.”

“Have you ever been – ” Denby hesitated. “Have you ever been in any sort of danger?”

“Yes,” Monty replied promptly, “but you pulled me out.”

“Please don’t go about repeating it,” Denby entreated, “I have enemies enough without being blamed for pulling you out of the Nashua river.”

Monty looked at him in astonishment. Here was the most popular boy in Groton School complaining of enemies. Monty felt a thrill that had something of enjoyment in it. His own upbringing had been so free from any danger and his parents had safeguarded him from so much trouble that he had found life insipid at times. Yet here was a man talking of enemies. It was fascinating.

“Do you mean it?” he demanded.

“Why not?” said Denby, rolling himself a cigarette.

“You hadn’t any at school,” Monty insisted.

“That was a dozen years ago nearly,” Denby insisted. “Since then – ” He paused. “My career wouldn’t interest you, my financial expert, but I am safe in saying I have accumulated a number of persons who do not wish me well.”

“You must certainly meet Alice,” Monty asserted. “She’s like you. She often says I’m the only really uninteresting person she’s fond of.”

Denby assured himself that Alice would not interest him in the slightest degree and made haste to change the subject, but Monty held on to his chosen course.

“We’ll all dine together to-morrow night,” he cried.

“I’m afraid I’m too busy.”

“Too busy to dine with Alice Harrington when you’ve the opportunity?” Monty exclaimed. “Are you a woman-hater?”

A more observant man might have noted the sudden change in expression that the name Harrington produced in Steven Denby. He had previously been bored at the idea of meeting a woman who he concluded would be eager to impart her guide-book knowledge. Alice evidently had meant nothing to him, but Alice Harrington roused a sudden interest.

“Not by any chance Mrs. Michael Harrington?” he queried.

Monty nodded. “The same. She and Michael are two of the best friends I have. He’s a great old sport and she’s hurrying back because he has to stay on and can’t get over this year.” Monty flushed becomingly. “I’m going back with her because Nora is going to stay down in Long Island with them.”

“Introduce me to Nora,” Denby insisted. “She is a new motif in your jocund song. Who is Nora, what is she, that Monty doth commend her?”

“She’s the girl,” Monty explained. He sighed. “If you only knew how pretty she was, you wouldn’t talk about a trap being baited. I don’t think women are the good judges they pretend to be!”

“Why not?” Denby demanded.

“Because Alice says she’d accept me and I don’t believe I stand a ghost of a chance.”

“Women are the only judges,” Denby assured him seriously. “If I were you I’d bank on your friend Alice every time.”

“Then you’ll dine with me to-morrow?” Monty asked.

“Of course. You don’t suppose I am going to lose sight of you, do you?”

And Monty, grateful that this admired old school friend was so ready to join him, forgot the previous excuse about inability to spare the time.

“That’s fine,” he exclaimed. “But what are we going to do to-night?”

“You are going to dine with me,” Denby told him. “I haven’t seen you, let me see,” he reflected, “I haven’t seen you for about ten years and I want to talk over the old days. What do you say to trying some of Marguery’s sole à la Normandie?”

During the course of the dinner Monty talked frankly and freely about his past, present and future. Denby learned that in view of the great wealth which would devolve upon him, his father had determined that he should become grounded in finance. When he had finished, he reflected that while he had opened his soul to his old friend, his old friend had offered no explanation of what in truth brought him to Europe, or why he had for almost a decade dropped out of his old set.

“But what have you been doing?” Monty gathered courage to ask. “I’ve told you all about me and mine, Steve.”

“There isn’t much to tell,” Denby responded slowly. “I left Groton because my father died. I’m afraid he wasn’t a shrewd man like your father, Monty. He was one of the last relics of New York’s brown-stone age and he tried to keep the pace when the marble age came in. He couldn’t do it.”

“You were going into the diplomatic service,” Monty reminded him. “You used to specialize in modern languages, I remember. I suppose you had to give that up.”

“I had to try to earn my own living,” Denby explained, “and diplomacy doesn’t pay much at first even if you have the luck to get an appointment.”

Monty looked at him shrewdly. He saw a tall, well set up man who had every appearance of affluence.

“You’ve done pretty well for yourself.”

Denby smiled, “The age demands that a man put up a good appearance. A financier like you ought not to be deceived.”

Monty leaned over the table. “Steve, old man,” he said, a trifle nervously, “I don’t want to butt in on your private affairs, but if you ever want any money you’ll offend me if you don’t let me know. I’ve too much and that’s a fact. Except for putting a bit on Michael’s horses when they run and a bit of a flutter occasionally at Monte Carlo I don’t get rid of much of it. I’ve got heaps. Do you want any?”

“Monty,” the other man said quietly, “you haven’t altered. You are still the same generous boy I remember and it’s good for a man like me to know that. I don’t need any money, but if ever I do I’ll come to you.”

Monty sighed with relief. His old idol was not hard up and he had not been offended at the suggestion. It was a good world and he was happy.

“Steve,” he asked presently, “what did you mean about having enemies and being in danger? That was a joke, wasn’t it?”

“We most of us have enemies,” Steven said lightly, “and we are all in danger. For all you know ptomaines are gathering their forces inside you even now.”

“You didn’t mean that,” Monty said positively. “You were serious. What enemies?”

“Enemies I have made in the course of my work,” the other returned.

“Well, what work is it?” Monty queried. It was odd, he thought, that Denby would not let him into so harmless a secret as the nature of his work. He felt an unusual spirit of persistence rising within him. “What work?” he repeated.

Denby shrugged his shoulders. “You might call it a little irregular,” he said in a lowered voice. “You represent high finance. Your father is one of the big men in American affairs. You probably have his set views on things. I don’t want to shock you, Monty.”

“Shock be damned!” cried Monty in an aggrieved voice. “I’m tired of having to accommodate myself to other people’s views.”

Denby looked at him with mock wonder.

“Monty in revolt at the established order of things is a most remarkable phenomenon. Have you a pirate in your family tree that you sigh for sudden change and a life on the ocean wave?”

Monty laughed. “I don’t want to do anything like that but I’m tired of a life that is always the same. You’ve enemies. I don’t believe I’ve one. I’d like to have an enemy, Steve. I’d like to feel I was in danger; it would be a change after being wrapped in wool all my life. You’ve probably seen the world in a way I never shall. I’ve been on a personally conducted tour, which isn’t the same thing.”

“Not by a long shot,” Steven Denby agreed. “But,” he added, “why should you want to take the sort of risks that I have had to take, when there’s no need? I have been in danger pretty often, Monty, and I shall again. Why? Because I have my living to make and that way suits me best. You notice I am sitting with my back to the wall so that none can come behind me. I do that because two revengeful gentlemen have sworn bloodthirsty oaths to relieve my soul of its body.”

Monty tingled with a certain pleasurable apprehension which had never before visited him. He was experiencing in real life what had only revealed itself before in novels or on the stage.

“What are they like?” he demanded in a low voice, looking around.

“Disappointing, I’m afraid,” Steven answered. “You are looking for a tall man with a livid scar running from temple to chin and a look before which even a waiter would blanch. Both my men have mild expressions and wouldn’t attract a second glance, but they’ll either get me or I’ll get them.”

“Steve!” Monty cried. “What did they do?”

Denby made a careless gesture. “It was over a money matter,” he explained.

Monty thought for a moment in silence. Never had his conventional lot seemed less attractive to him. He approached the subject again as do timid men who fearfully hang on the outskirts of a street fight, unwilling to miss what they have not the heart to enjoy.

“I wish some excitement like that would come my way,” he sighed.

“Excitement? Go to Monte and break the bank. Become the Jaggers of your country.”

“There’s no danger in that,” Monty answered almost peevishly.

“Nor of it,” laughed his friend.

“That’s just the way it always is,” Monty complained. “Other fellows have all the fun and I just hear about it.”

Denby looked at him shrewdly and then leaned across the table.

“So you want some fun?” he queried.

“I do,” the other said firmly.

“Do you think you’ve got the nerve?” Steven demanded.

Monty hesitated. “I don’t want to be killed,” he admitted. “What is it?”

“I didn’t tell you how I made a living, but I hinted my ways were a bit irregular. What I have to propose is also a trifle out of the usual. The law and the equator are both imaginary lines, Monty, and I’m afraid my little expedition may get off the line. I suppose you don’t want to hear any more, do you?”

Monty’s eyes were shining with excitement. “I’m going to hear everything you’ve got to say,” he asserted.

“It means I’ve got to put myself in your power in a way,” Denby said hesitatingly, “but I’ll take a chance because you’re the kind of man who can keep things secret.”

“I am,” Monty said fervently. “Just you try me out, Steve!”

“It has to do with a string of pearls,” Denby explained, “and I’m afraid I shall disappoint you when I tell you I’m proposing to pay for them just as any one else might do.”

“Oh!” said Monty. “Is that all?”

“When I buy these pearls, as you will see me do, with Bank of France notes, they belong to me, don’t they?”

“Sure they do,” Monty exclaimed. “They are yours to do as you like with.”

“That’s exactly how I feel about it,” Denby said. “It happens to be my particular wish to take those pearls back to my native land.”

“Then for heaven’s sake do it,” Monty advised. “What’s hindering you?”

“A number of officious prying hirelings called customs officials. They admit that the pearls aren’t improved by the voyage, yet they want me to pay a duty of twenty per cent. if I take them home with me.”

“So you’re going to smuggle ’em,” Monty cried. “That’s a cinch!”

“Is it?” Denby returned slowly. “It might have been in the past, but things aren’t what they were in the good old days. They’re sending even society women to jail now as well as fining them. The whole service from being a joke has become efficient. I tell you there’s risk in it, and believe me, Monty, I know.”

“Where would I come in?” the other asked.

“You’d come in on the profits,” Denby explained, “and you’d be a help as well.”

“Profits?” Monty queried. “What profits?”

Denby laughed. “You simple child of finance, do you think I’m buying a million-franc necklace to wear about my own fair neck? I can sell it at a fifty thousand dollar profit in the easiest sort of way. There are avenues by which I can get in touch with the right sort of buyers without any risk. My only difficulty is getting the thing through the customs. It’s up to you to get your little excitement if you’re game.”

Monty shut his eyes and felt as one does who is about to plunge for the first swim of the season into icy water. It was one thing to talk about danger in the abstract and another to have it suddenly offered him.

Steven had talked calmly about men who wanted to part his soul from his body as though such things were in no way out of the ordinary. Suppose these desperate beings assumed Montague Vaughan to be leagued with Steven Denby and as such worthy of summary execution! But he put aside these fears and turned to his old friend.

“I’m game,” he said, “but I’m not in this for the profits.” Now he was once committed to it, his spirits began to rise. “What about the danger?” he asked.

“There may be none at all,” the other admitted. “If there is it may be slight. If by any chance it is known to certain crooks that I have it with me there may be an attempt to get it. Naturally they won’t ask me pleasantly to hand it over, they’ll take it by force. That’s one danger. Then I may be trailed by the customs people, who could be warned through secret channels that I have it and am purposing to smuggle it in.”

“But what can I do?” Monty asked. He was anxious to help but saw little opportunity.

“You can tell me if any people follow me persistently while we’re together in Paris or whether the same man happens to sit next to me at cafés or any shows we take in.” He paused a moment, “By Jove, Monty, this means I shall have to book a passage on the Mauretania!”

“That’s the best part of it,” Monty cried.

“But Mrs. Harrington,” Denby said. “She might not like it.”

“Alice can’t choose a passenger list,” Monty exclaimed; “and she’ll be glad to have any old friend of mine.”

“That’s a thing I want to warn you of,” the other man said. “I don’t want you to give away too many particulars about me. Don’t persist in that fable about my saving your life. Know me just enough to vouch to her that I’m house-broken but don’t get to the point where we have to discuss common friends. I have my reasons, Monty, which I’ll explain later on. I don’t court publicity this trip and I don’t want any reporter to jump aboard at Quarantine and get interested in me.”

“I see,” cried the sapient Monty and felt he was plunging at last into dark doings and mysterious depths. “But how am I to warn you if you’re followed? I shall be with you and we ought not to let on that we know.” He felt in that moment the hours he had spent with detective novels had been time well spent.

“We must devise something,” Denby agreed, “and something simple.” He meditated for a moment. “Here’s an idea. If you should think I’m being followed or you want me to understand that something unusual is up, just say without any excitement, ‘Will you have a cigarette, Dick?’”

“But why ‘Dick,’” Monty cried, “when you’re Steve!”

“For that very reason,” Denby explained. “If you said Steve merely I shouldn’t notice it, but if you say Dick I shall be on the qui vive at once.”

“Great idea!” cried his fellow conspirator enthusiastically. “When do you buy them?”

“I’ve an appointment at Cartier’s at eleven. Want to come?”

“You bet I do,” Monty asserted, “I’m going through with it from start to finish.”

He looked at his friend a little anxiously. “What is the worst sort of a finish we might expect if the luck ran against us?”

“As you won’t come in on the profits, you shan’t take any risks,” Denby said. “If you agree to help me as we suggested that’s all I require of you. In case I should not get by, you can explain me away as a passing acquaintance merely. Don’t kick against the umpire’s decision,” he commanded. “If they halved the sentence because two were in it I might claim your help all the way, but they’d probably double it for conspiracy, so you’d be a handicap. You’ll get a run for your money, Monty, all right.”

“I’m not so sure,” said Monty doubtfully.

Denby fell into the bantering style the other knew so well. “There’s one thing I’ll warn you about,” he said. “If a very beautiful young woman makes your acquaintance on board, by accident of course, don’t tell her what life seems to you as is your custom. She may be an agent of the Russian secret police with an assignment to take you to Siberia. She may force you to marry her at a pistol’s point and cost your worthy progenitor a million. Be careful, Monty. You’re in a wicked world and you’ve a sinful lot of money, and these big ships attract all that is brightest and best in the criminal’s Who’s Who.”

Monty shivered a bit. “I never thought of that,” he said innocently.

“Then you’d better begin now,” his mentor suggested, “and have for once a voyage where you won’t be bored.”

He glanced at the clock. “It’s later than I thought and I have to be up early. I’ll walk to your hotel.”

During the short walk Monty glanced apprehensively over his shoulder a score of times. Out of the shadows it seemed to him that mysterious men stared evilly and banded themselves together until a procession followed the two Americans. But Denby paid no sort of attention to these problematic followers.

“Wait till I’ve got the pearls on me,” he whispered mischievously. “Then you’ll see some fun.”
