Mr. Ludgrove gazed up at him in mock alarm. “They do, indeed,” he replied. “It makes my blood run cold to think that I am one of them. Really, I am quite relieved to think that I have an alibi in the case of this last murder, at least.”

Inspector Whyland laughed shortly. “Oh, for that matter, I’m as much under suspicion as you,” he said. “But, you see, there are some people we know who couldn’t produce an alibi for the time when any of the murders were committed.”

And with that he turned abruptly on his heel and strode out of the room.
