me a bob, an' 'e arsks me wot's the matter. I'd been on the ranks four bloomin' hours--" "Oh, there you are!" and Bruce threw him half-a-crown before he disappeared up the steps. Mr. White was watching for Bruce's arrival. He wondered why the barrister was so perturbed, and resolved to strike while the iron was hot. So he, too, vanished into the interior. CHAPTER XIII A QUESTION OF PRINCIPLE "If any one calls, I am out," cried Claude to his factotum, as he crossed the entrance-hall of his well-appointed flat, and flung open the door of his library. "The guv'nor's in a tantrum," observed Smith to his wife, and he settled himself to renew the perusal of Grand National training reports. He had just noticed the interesting fact that last year's winner had "jumped in for the last mile" in a gallop given to a rank outsider, when the electric bell upset his calculations.

He wanted to think, not to be bothered by official theories. He looked hard at Mr. White, wondering whether he should tell him all he knew and wash his own hands clear of the investigation in future. But there was a second picture before his eyes. He saw Phyllis Browne's face, not as it was that day at the Tir aux Pigeons, but with the light of happiness in it, with the joyousness of requited and undisturbed love, with the glow reflected from dancing waves, and the tremulous smile of innocent pleasure. It was hard to believe that such a woman could place her heartfelt trust in a man who was possibly a cold-blooded murderer. Such a combination was unnatural and horrible. Already Bruce was beginning to doubt the evidence of his analytical senses. Mr. White
