There was something in Mr. Jellicoe's passionless tone that disturbed the inspector exceedingly, for he turned to Thorndyke and said in a low tone:
"I wonder what his game is? He can't get away, you know."
"There are several possibilities," said Thorndyke.
"M'yes," said Badger, stroking his chin perplexedly.
"After all, is there any objection? His statement might save trouble, and you'd be on the safe side. It would take you some time to break in."
"Well," said Mr. Jellicoe, with his hand on the window, "do you agree—yes or no?"
"All right," said Badger sulkily. "I agree."
"You promise not to molest me in any way until I have quite finished?"
"I promise."
Mr. Jellicoe's head disappeared and the window closed. After a short interval we heard the jar of massive bolts and the clank of a chain, and, as the heavy door swung open, Mr. Jellicoe stood revealed, calm and impassive, with an old-fashioned office candlestick in his hand.
