“You have rendered yourself liable to a strong suspicion of having committed the other murders which have disgraced our city.”

“No, no, indeed!” said Von Schlegel, earnestly. “God forbid!”

“At least you are guilty of attempting the life of Herr Leopold Strauss.”

“The dearest friend I have in the world,” groaned the student. “Oh, how could I! How could I!”

“His being your friend makes your crime ten times more heinous,” said the inspector, severely. “Remove him for the remainder of the night to the—— But steady! Who comes here?”

The door was pushed open and a man came into the room, so haggard and careworn that he looked more like a ghost than a human being.

The practised eye of Baumgarten, however, was not to be baffled by any change.
