As he straightened himself after his brief examination, his eyes went instinctively to the window; but he was not quick enough. Had he been a second earlier he would have seen the white face of a man, pressed against the glass outside, taking in every detail of the room and its grim occupant. As he was in the very act of raising his head the watcher ducked below the sill of the window and when, a few minutes later, he ran out of the front door, after a hurried search through the house, there was no one either in the barn or any of the outhouses. The unseen watcher at the window had vanished like a shadow into the darkness of the night. Chapter II Police Constable George Gunnet bent down with a grunt of satisfaction and slowly unlaced his second boot. He was not a quick mover at the best of times and the pleasant kitchen, with its glowing fire and appetizing aroma of toasted cheese, was conducive to drowsiness. He had just come in from his last round and, to one fresh from the wild night outside, the kitchen was a haven of peace and comfort. His tunic hung over the back of a chair and he sat, very much at ease, in his shirt-sleeves, waiting for Mrs. Gunnet to finish her bustling preparations for the supper he felt he had more than earned. “Nobody been, I suppose?” he asked, according to custom, as he filled his pipe. “Who should have been?” his wife countered tartly. Mrs. Gunnet had once, some twenty years ago, been in service in Glasgow and, as she often said, never could get used to a dead-alive little place like Keys. “Nothing ever happens here, as I’m aware of.” Gunnet stretched his legs luxuriously towards the warm glow of the fire. “There’s quite enough happening for me, if it’s all the same to you,” he said comfortably. “There’s a big elm down in Fanning’s meadow and there’ll be more before morning if this goes on. All I could do to stand up against the wind at the Four Corners and it fair blew me home. Oye, shut the door, can’t you?” He made a grab at the newspaper as, in the path of the wind, it leaped from the table and scudded across the room into a corner. It was followed by a half-empty packet of tobacco which he was too late to save. “Here, will you shut that door!” he shouted, his head half under the table. Then, emerging and catching sight of the visitor: “Beg your pardon, Mr. Leslie; I didn’t see as it was you. What with that outer door opening straight onto this room like, the wind comes in something cruel.” But Mrs. Gunnet’s sharp eyes had already detected something unusual in the caller’s bearing. “There’s nothing wrong, is there, sir?” she broke in. “Was you coming after George?” The newcomer nodded. He was panting with the haste in which he had come and his face had a queer, grey look underneath the natural tan of an open-air man. When he spoke it was in a hard, dry voice, carefully devoid of all emotion, as if he were afraid that, at any moment, it might get beyond his control.
