whole-meal biscuits, possibly a wooden vesta, and perhaps even the missing hat."
At the mention of the hat, the inspector stepped eagerly to the back door, but, finding it bolted, he tried the window. This also was securely fastened and, on Thorndyke's advice, we went round to the front door.
"This door is locked too," said the inspector. "I'm afraid we shall have to break in. It's a nuisance, though."
"Have a look at the window," suggested Thorndyke.
The officer did so, struggling vainly to undo the patent catch with his pocket-knife.
"It's no go," he said, coming back to the door. "We shall have to" He broke off with an astonished stare, for the door stood open and Thorndyke was putting something in his pocket.
"Your friend doesn't waste much time—even in picking a lock," he remarked to me, as we followed Thorndyke into the house; but his reflections were soon merged in a new surprise. Thorndyke had preceded us into a small sitting-room dimly lighted by a hanging lamp turned down low.
As we entered he turned up the light and glanced about the room. A whisky-bottle was on the table, with a siphon, a tumbler and a biscuit-box. Pointing to the latter, Thorndyke said to the inspector: "See what is in that box."
