"Yes," replied Galloway. "It was raining heavily last night."

With eyes sharpened by his discoveries, Galloway made a careful search of the carpet, and found several more crumbs of red clay between the window and the bed. Near the bed he detected some splashes of candle-grease, which he detached from the carpet with his pocket-knife. He also picked up the stump of a burnt wooden match, and the broken unlighted rink head of another. After showing these things to his companions he placed them carefully in an empty match-box, which he put in his pocket.

"Somebody has bumped against this gas globe pretty hard," said Colwyn. "The glass is broken and the incandescent burner smashed."

He bent down to examine the white fragments of the burner which were scattered about the carpet, and as he did so he noticed another broken wooden match, and two more splashes of candle-grease directly beneath the gas-jet. He removed the candle-grease carefully, and showed it to Galloway.

"More candle-grease!" the latter said. "Well, that's not likely to prove anything except that Ronald was careless with his light. I suppose the wind caused the candle to gutter. I would willingly exchange the candle-grease for some finger-prints. There's not a sign of finger-prints anywhere. Ronald must have worn gloves. Now, let us have a look at Ronald's room. I want to see if he could get out of his own window on to the hillside. His window is higher from the ground than this window. The hill falls away very sharply."

The bedroom Ronald had occupied was small and narrow, and its meagre furniture was in striking contrast with the comfortable appointments of the room they had just left. It contained a single bed, a chest of drawers, a washstand, and a wardrobe. The latter, a cumbrous article of furniture, stood between the bed and the wall, against the side nearest to Mr. Glenthorpe's room.

Galloway strode across to the window, which was open, and looked out. The hillside fell away so rapidly that the bottom of the window was quite eight feet from the ground outside.

"Not much of a drop for an athletic young fellow like Ronald," said Galloway to Colwyn, who had joined him.

"The window is very much smaller than the one in Mr. Glenthorpe's bedroom," said Colwyn.

"But large enough for a man to get through. Look here! I can get my head and shoulders through, and where the head and shoulders go the rest of the body will follow. Ronald got through it last night and into the next room by the other window. There can be no doubt that that was how the murder was committed."
