"Partly," he returned, "and partly not. I've made no accusation, Cyril, but--things point very blackly to your brother, and it will take pretty strong evidence to say he is innocent at this juncture of the case, at any rate. There are--others--whom I doubt, but at the present moment doubts are all that can be expected of me. Certainties will follow later.... Now, look here, you can help considerably. Tell me, who's been tinkering with the electric switches in the library lately?" Of a sudden the boy's face went red and whity by turns. Then he averted his head and pretended to inspect a fly that was crawling upon the opposite wall. "Er--I don't really know," he replied in a confused voice. "I haven't the faintest----" "You do!" Cleek had caught him by the shoulders and whirled him around so that eye met eye squarely, and he saw that the boy dropped his. "Come, now. Play the game. I can't expect to find the true murderer unless you tell the truth. Listen to me, Cyril. Was it your brother Ross?" Came a long silence, followed by a quickly drawn breath. Then: "_I_ have." "You? What the dickens did you do? Tell me all about it, quickly. I found a bit of flexible wire upon the carpet yesterday morning when I was looking over the house with your stepsister, and came to the conclusion that someone had been altering the lights. And it was you, was it?" Again the flushed cheeks and quickly drawn breath. Oh, this quixotic family!--that muddled a decent man up in trying to do his duty by their perpetual affections and efforts to shield one another. "Yes--and no. It was the day before yesterday. Ross and Mr. Tavish were in the library going over some land accounts and looking at the weekly wages bill, which is part of Ross's work for Father that he's been doing the past two years. I was there, too, mending a damaged switch which wouldn't go right, and Ross had promised to help me when his business was finished. Well, when it was done, and they had smoked a cigarette together-- Mr. Tavish is awfully popular with the whole place, you know, Mr. Deland, and Ross liked him immensely--well, as I was saying, when they'd done, they came over to me, where I was tinkering away at the switch by the wall, and while Ross explained to me what exactly was the matter, Mr. Tavish stood over us and made remarks." "Can you remember what any of those remarks were?" "Yes. He said he thought I was growing to be a clever youngster, with a turn for electricity which ought to drive my father nearly mad, and then he shook his head, and Ross laughed sort of uncomfortably, and agreed with him. And then Ross asked Mr. Tavish if he knew anything of electricity. 'Not a blessed thing!' Mr. Tavish said, with a loud laugh. 'I don't know the difference between a short circuit and a Bath bun.' And of course we all laughed again, and then Ross explained a little of it to him, and he seemed to catch on awfully quick, and asked some jolly interestin' questions."
