A single human being, the figure of a tall man clad in an ulster buttoned up to the throat, was making his way across the open country. He walked rapidly--and, indeed, there was nothing to tempt any one to linger--and his destination was obvious. He was on his way to Falcon's Nest. A drearier abode than it appeared that afternoon never raised its four walls to the sky. The grounds which surrounded it had been swept bare by the storms of winter, and nothing had been done to repair the destruction which they had accomplished. Uprooted shrubs lay dead and dying upon the long dank grass, and the creepers torn from the walls hung down in pitiful confusion. Every window reflected back the same blank uninviting gloom. There was no light, no single sign of habitation. Mr. Thurwell had evidently respected his tenant's wish to the letter. The place had not been touched or entered during his absence. The pedestrian, Mr. Bernard Brown himself, leaned over the gate for a moment, silently contemplating the uninviting scene with a grim smile. He had reasons of his own for being satisfied that the place had not been interfered with, and it certainly seemed as though such were the case. After a few minutes' hesitation he drew a key from his pocket and fitted it in the lock. There was a resistance when he tried to turn it that he did not understand. Stooping down, he suddenly tried the handle. It opened smoothly. The gate was unlocked. He withdrew the key with trembling fingers. All his relief at the dismantled appearance of the cottage had disappeared. A strange unquiet look shone in his eyes, and his manner suddenly became nervous and hurried. He had locked the gate on his departure, he was sure, and Mr. Thurwell's steward had told him that there was no duplicate set of keys. How could it have been opened save with a skeleton key. He walked quickly up the path to the front door. Here a greater shock still awaited him. The latch-key which he held ready in his hand was not needed. He tried the handle, and the door opened. Mr. Brown grew white to the lips, and he shrank back as though afraid or reluctant to enter the house. The door stood ajar. He pushed it open with his stick, and peered in upon the darkness. Everything was silent as the grave. He listened for a moment, and then, his natural courage returning, he stepped inside, and closed the door after him. The shutting out of the few gleams of daylight which lingered in the sky left him in utter darkness. Fumbling in his pocket, he produced a wax candle wrapped in a piece of newspaper, and a box of matches, one of which he carefully struck. At first the gloom seemed too profound to be dispersed by the feeble flickering light, but gradually, as his eyes became accustomed to it, he began to distinguish the more familiar objects. Half fearfully he glanced towards the door on the right-hand side. It stood half open. There was no longer room for any doubt. The house had been opened during his absence.
