Hmn---- Pay him? So that was how the land lay, was it? The boy was heavily in debt to Blake, and if he had been at Cheyne Court that night.... No, that was wrong, too, for there had been no trace of Bobby Wynne--up to the present. Meanwhile that young gentleman was obviously waiting to lead him downstairs, and Cleek hesitated, trying to make up his mind what to do for the best. He would have liked to stay in this racing den, try to trace the connection between Blake the tipster and Blake the head of the Pentacle Club, and to find out whether Master Bobby Wynne had had any suspicions as to the real identity of the "mistress" of Cheyne Court. But other things called. There was that Verrall chap downstairs with Jennifer Wynne herself. And the question of those utterly priceless flowers that could fetch as much as fifty pounds for their grower. Silently he followed his host downstairs, still looking a bit hang-dog about the mouth for he was far too careful in his methods to cast any doubt regarding the genuineness of that sudden attack of a moment before by pretending that it was already over. Nor did he fear that he had lost all opportunity for pursuing the subject of Bobby Wynne's acquaintance with the murdered man. The mere fact that the young man feared discovery of his connection with this Blake proved conclusively that he knew his danger and that at any moment inquiry might be made, even though there was no actual proof that he had been in the vicinity of Cheyne Court that night. "Fearfully groggy, old chap," he said in answer to Wynne's inquiry as to whether he felt any better. They were passing down a dark, narrow passage at the moment and a little door stood ajar toward the end of it. A quick glance showed Cleek that the room beyond this door was lined with shelves on which stood numerous rows of bottles. Bobby Wynne's face seemed to whiten with unwonted anger. He gave a sharp exclamation, and ran back to close the door quickly. "The old guv'nor's surgery," he said in explanation. "Wonder who's been in? Door's been kept locked ever since the old man died. Hullo, Headland, you're not going to have another attack, are you?" For Cleek had suddenly lurched against the bannister at the head of the stairs, and swung round, until his back was resting against it. He lolled his head back, gave a sort of hollow groan, and then under cover of this began swiftly to count the doors in order to make sure of the location of that surgery. "No, it's only just a passing spasm. I was just wondering whether your old dad had anything in his surgery to pull me together, clever chaps some of these doctors, dontcher know."
