"This is the room," he said, in a low voice. It was Colwyn's keen eye that noted the key in the door. "What is that key doing in the door, on the outside?" he asked. "How long has it been there?"

"The maid found it there this morning, sir, when she went up with Mr. Glenthorpe's hot water. That made her suspect something must be wrong, because Mr. Glenthorpe was in the habit of locking his door of a night and placing the key under his pillow. So, after knocking and getting no answer, she opened the door, and found the room empty."

"The door was not locked, though the key was in the door?"

"No, sir, and everything in the room was just as usual. Nothing had been disturbed."

"And was that bedroom window open when you found the room empty?" asked Superintendent Galloway, pointing to it through the open doorway.

"Yes, sir—just as you see it now. I gave orders that nothing was to be touched."

"Ronald slept in this room," said Queensmead, indicating the door of the adjoining bedroom.

"We will look at that later," said Galloway.

The interior of the room they entered was surprisingly light and cheerful and spacious, having nothing in common with those low gloomy vaults, crammed with clumsy furniture and moth-eaten stuffed animals, which generally pass muster as bedrooms in English country inns. Instead of the small circular windows of the south side, there was a large modern two-paned window in a line with the door, opening on to the other side of the house. The bottom pane was up, and the window opened as wide as possible. A very modern touch, unusual in a remote country inn, was a rose coloured gas globe suspended from the ceiling, in the middle of the room. The furniture belonged to a past period, but it was handsome and well-kept—a Spanish mahogany wardrobe, chest of drawers and washstand with chairs to match. Modern articles, such as a small writing-desk near the window, some library books, a fountain pen, a reading-lamp by the bedside, and an attaché case, suggested the personal possessions and modern tastes of the last occupant. A comfortable carpet covered the floor, and some faded oil-paintings adorned the walls.

The bed—a large wooden one, but not a fourposter—stood on the left-hand side of the room from the entrance, with the head against the wall nearest the outside passage, and the foot partly in line with the open window, which was about eight feet away from it. The door when pushed back swung just clear of a small bedroom table beside the bed, on which the reading lamp stood, with a book beside it. The other side of the bed was close to the wall which divided the room from the next bedroom, so that there was a large clear space on the outside, between the bed and the door. The gas fitting, which was suspended from the ceiling in this open space, hung rather low, the bottom of the globe being not more than six feet from the floor. The globe was cracked, and the incandescent burner was broken.
