"No, thanks; we'd prefer to take it with you." ("And use our eyes for ourselves," he supplemented silently.) Then, without more ado, bowed and left her, and went off in pursuit of the Superintendent, who had been spending a quiet hour investigating the scene of last night's tragedy, and trying to solve the riddle of it.

Halfway there Cleek encountered young Cyril, wandering disconsolately about, hands in pockets and head downthrown, and at sight of Cleek he fairly ran up to him, his brows black as thunder, his young mouth set into an ugly line.

"Look here," he demanded, in his shrill young voice, planting himself in Cleek's way and looking up into his face, "they've been telling me you suspect my stepbrother Ross of murdering my father last night, and I've been waiting to catch you and to tell you it's a damned lie!"

"Easy, easy, my young enthusiast," returned Cleek, with a throb of admiration for this fearless young person, nevertheless. "They'll never make a detective of you if your methods of attack don't improve hastily. Let's hear what you're worrying over. Now, then, all over again. I'm going along this way to see the Superintendent, and you can come with me if you like."

Cyril's face went a dull brick-red at Cleek's bantering tone, and his lips twitched. He swung into step beside Cleek as they traversed the long hall toward the library.

"They've been telling me," he reiterated, "that you think my stepbrother Ross killed Father last night, and——"

"Who's 'they,' may I ask?"

"Oh—Mother—Miss Dowd, Cynthia—the whole bally lot of 'em. Said you'd threatened to arrest Ross and put—put him in prison. But it isn't true, sir, is it?"

Cleek looked down at the eager young face, and sighed.

"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?"
