“He came in by the front door. The lock has not been injured, so apparently he has a key. You hide in the room on the left—just inside, close to the door. I will hide in the cupboard underneath the staircase. When he reaches the clock he cannot escape without passing us. Give him time to get the money, and as soon as he has the bags in his hands ready to start off, we will both spring out at him.”

Crewe watched Marsland enter the sitting-room on the left and then opened the door of the cupboard beneath the staircase and crouched down. The cupboard opened into the hall, and through the crack of the door Crewe was able to see into the room where the shattered clock was. The door of the room where Marsland was hidden also commanded a view of the interior of the room in which the clock stood. The stillness was so complete that Crewe could hear the watch in his pocket ticking off the ebbing moments. Once the distant yelp of a sheep-dog reached him, then there was another long period of stillness. Twice his keen ear caught a faint creaking in the old house, but he knew they were but the mysterious night noises which are so common in all old houses: the querulous creakings and complaints of beams and joists which have seen many human generations come and go.

But, as the time dragged on without a sound to indicate that the thief was returning, Crewe found to his vexation that he had increasing difficulty in keeping his senses alert in that dark and muffled silence. The close and confined atmosphere of the cupboard, the lack of air, his cramped position, compelled an unconquerable drowsiness.

Then he heard a sound which drove away his drowsiness—the sound of a key in a lock. He heard the door creak as it was pushed back and then came steps advancing along the hall, stumbling along noisily, as though their owner thought that the need for precautions ceased when the front door was passed: that once inside the house he was safe, and need not fear interruption.

There was a scrape and a splutter, and a flickering flame in the hall; the thief had struck a match. Through the crack of the cupboard door Crewe watched the tiny blue flame grow larger, turn yellow, and burn steadily, and he could see the dim outline of a man’s back and a hand shielding the match showing transparent through the flame. The thief had struck his match with his face to the doorway. The outline of his other hand approached, and the light grew brighter—the intruder had lit a piece of candle. As it burnt up the man turned towards the clock, and Crewe saw the face of Brett for the first time. His impression was of a pair of hunted nervous eyes roving restlessly in a livid waxen mask, a tense sucked-in mouth.

He saw no more. Apparently Marsland had been too excited to wait until the thief had the bags in his hands, for Brett started as though he heard a movement, and quickly extinguished his candle. There was a moment of intense silence, and then Crewe heard Marsland’s voice raised in a strange high-pitched scream that made it seem unfamiliar.

“Powell, you traitor and murderer! I am Marsland—Captain Marsland. I will kill you without sending you to trial.”

Crewe had thrown open the door of the cupboard at the first sound of the voice, but before he could get on to his feet there was the deafening sound of a revolver shot, followed by the rush of feet and the fall of a body.

The bullet had missed the thief, and Marsland, advancing on him after firing, had been knocked over by Brett’s rush for the door. Before Crewe could reach him across Marsland’s prostrate form Brett had thrown open the door and was outside the house.

Crewe dashed for the door in pursuit. He caught a glimpse of a fleeing figure, bent nearly double to shield himself from another shot, running down the gravel path at amazing speed. Then the figure was swallowed up in the night.
