"Yes, I have," was the whispered reply. "My brother could not manage to get up the stairs. He has one of his very bad attacks to-day. He has not the least idea that I know anything. He said he dropped an unaddressed letter on this landing last night, and he asked me to fetch it. I dare not stay a minute." "Don't go quite yet," Berrington pleaded. "I have had a brilliant idea. I can't stop to tell you what it is just now. The switch of the electric light has been removed from here. Can you tell me where I can find it?" "You want more light?" Mary asked. "Well, it is a little dreary in there with only a lamp. The switch was taken off some time ago when the walls were being done, and the electricians forgot to replace it. It is somewhere in the room, for I recollect seeing it. But unless you understand that kind of work----" "Oh, soldiers understand something of everything," said Berrington cheerfully. "I shall be able to manage, no doubt. I won't detain you any longer." Mary slipped away, and Berrington commenced to make a careful search of the room. He found what he wanted presently, in a little blue cup on the overmantel, and in a few minutes he had fixed the switch to the wall. As he pressed the little brass stud down, the room was flooded with a brilliant light. "There's some comfort in being able to see, at any rate," Berrington reflected. "It's ten chances to one that my little scheme does not come off, yet the tenth chance may work in my favour. I'll wait till it gets dark--no use trying it before." Berrington dozed off in his chair, and soon fell into a profound sleep. When he came to himself again, a clock somewhere was striking the hour of eleven. There was no stream of light through the little round ventilator in the shutter, so that Berrington did not need to be told that the hour was eleven o'clock at night. "By Jove, what a time I've slept," the soldier muttered. "What's that?" Loud voices downstairs, voices of men quarrelling. Berrington pulled the whistle out of the tube and listened. Someone had removed the whistle from the other end, or else it had been left out by accident, for the sound came quite clear and distinct. It was the voice of Sartoris that was speaking, a voice like a snarling dog. "I tell you you are wrong," Sartoris said. "You tried to fool me, and when we make use of you and get the better of you, then you whine like a cur that is whipped. Don't imagine that you have your poor misguided wife to deal with." "My wife has nothing to do with the case," the other man said, "so leave her out." Berrington's heart was beating a little faster as he glued his ear to the tube. He did not want to miss a single word of the conversation. "This grows interesting," he said softly. "A quarrel between Sartoris and Stephen Richford. Evidently I am going to learn something."
