Havoc by E. Phillips Oppenheim

Certainly it was a strange little gathering that waited in Morrison's room for the coming of Laverick. There was Lassen-flushed, ugly, breathing heavily, and watching the door with fixed, beady eyes. There was Adolf Kahn, the man who had strolled out from the Milan Hotel as Laverick had entered it, leaving the forged order behind him. There was Streuss-stern, and desperate with anxiety. There was Morrison himself, in the clothes of a workman, worn to a shadow, with the furtive gleam of terrified guilt shining in his sunken eyes, and the slouched shoulders and broken mien of the habitual criminal. There was Zoe, around whom they were all standing, with anger burning in her cheeks and gleaming out of her passion-filled eyes. She, too, like the others, watched the door. So they waited.

Streuss, not for the first time, moved to the window and drawing aside the curtains looked down into the street.
