"The murderer entered through the window." The others went over to the window. The inn on that side had been built into a small hill of beehive shape, which had been partly levelled to make way for the foundations. Seen from outside, the inn, with its back to the sea and a corner of its front entering the hillside, bore a remote resemblance to some nakedly ugly animal with its nose burrowed into the earth. Part of the bar was actually underground, and the windows of the rooms immediately above looked out on the hillside. The window of Mr. Glenthorpe's room, which was above the bar parlour, was not more than four or five feet away from the round-shouldered side of the hill. From that point the hill fell away rapidly, and the first-story windows at the back, where the house rose from the flat edge of the marsh, were about fifteen feet from the ground. The space between the inn wall and the beehive curve of the hill, which was very narrow under Mr. Glenthorpe's window, but widened as the hill fell away, was covered with a russet-coloured clay, which contrasted vividly with the sombre grey and drab tints of the marshes. "It was an easy matter to get in this window," said Superintendent Galloway. "And here's the proof that the murderer came in this way." He stooped and picked up something from the floor, close to the window, and held it out in the palm of his hand for the inspection of his companions. It was a small piece of red clay, like the russet-coloured clay outside the window. "Here is another clue," said Colwyn, pointing to a fragment of black material adhering to a nail near the bottom of the window. "Ronald ripped something he was wearing while getting through the window," said Galloway, detaching the fragment, which he and Colwyn examined closely. "Have you noticed that?" said Colwyn, pointing to a pool of water which had collected near the open window, between the edge of the carpet and the skirting board. "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.
