Guilty Bonds

In Guilty Bonds by William Le Queux, newly rich Frank Burgoyne falls in love with a Russian spy only to become involved in a massive, international plot concerning a series of murders. Excerpt: «Come, have another hand, Burgoyne.» «I'll have my revenge tomorrow, old fellow,» I replied. «Why not tonight?» «It's past two, and I have a long walk home, remember.» «Very well; as you wish.»
