Half-past two had chimed, and it was the darkest hour which precedes the dawn, when we all started as a low but sharp click came from the direction of the gate. Someone had entered the drive. Again there was a long silence, and I had begun to fear that it was a false alarm, when a stealthy step was heard upon the other side of the hut, and a moment later a metallic scraping and clinking. The man was trying to force the lock. This time his skill was greater or his tool was better, for there was a sudden snap and the creak of the hinges. Then a match was struck, and next instant the steady light from a candle filled the interior of the hut. Through the gauze curtain our eyes were all riveted upon the scene within.
