"I don't know, sir," the boy said humbly. "I don't know how it was done. Ah, that there Raffle is a deep 'un. I made sure as the trial the other morning was all open and above board, and now I find as how it wasn't the Blenheim colt we saw at all. It is no use asking me to explain, gentlemen, and it is no use bullying me, for the more you do that the more muddled I get. It is only a word or two I 'eard between Raffle and the 'ead lad that put me on the scent. We've got two or three 'osses in the stable as like the Blenheim colt as two peas. They are nearly all the same blood, you know. What old Raffle is a-driving at, I dunno. But it looks as if one colt was changed for another at the last moment, and nobody would have been any the wiser if I hadn't 'eard that little conversation this blessed morning."

Copley and Foster exchanged glances. It was no use to scarify the boy, for the conspiracy was none of his making, and he was obviously telling the truth; indeed, he had been well paid to bring information to Copley and had nothing to gain by further deception. But what was the meaning of it all? Why had Raffle chosen to bring off a mock trial? So far as Copley knew, Raffle had no reason to suspect the honesty of the stable boy. He could not know that he was in Copley's pay, nor could he have known, either, that Copley and Foster would witness that early morning trial. Could it be that there was some one else in the field whom Raffle wished to deceive? At any rate, whether that was so or not, Joe Raffle had put both Copley and his accomplice in a hole. After witnessing the trial they had laid against the colt to an enormous amount, and, after all, Sir George Haredale's horse might win the Derby. They dismissed the boy with strict injunctions to keep his eyes open and let them know the latest developments. Then they talked the matter over to see if they could find some way out of the trouble.

"It's a bit of a facer," Copley muttered. "I am bound to confess I never expected anything like this. I wonder what that old fox Raffle was driving at? Whom is he trying to deceive? I'd give something to know."

"What does it matter?" Foster asked impatiently. "Wilfully or not, he has deceived us. As I figure it out, we stand to lose something like five thousand pounds. If that horse starts fit and well for the Derby we shall be in a rare mess. And there's nothing to beat the colt. It would be maddening to be done at the beginning of the season. Fancy having to upset all our plans because of a misfortune like this!"

"Unless we could stop the colt," Copley suggested.

Foster looked keenly across the table at his companion.

"That's not a bad idea," he said thoughtfully. "If the Blenheim colt lost the Derby we should win ten thousand pounds at least. At the price the horse stands in the betting to-day, we could lay another twenty thousand pounds without knocking him altogether out of the betting. I don't call to mind a case in which the public have been more infatuated about a horse. Why, our commission never shook him at all. Suppose, without anybody knowing it, we could guarantee that the horse didn't start. In that case, we could lay a hundred thousand pounds against him, with the absolute knowledge that it would be only a question of time before we scooped up the money. Our Mirst Park scheme is a mere fleabite to it."

Copley's sombre eyes lighted a little.

"Yes, if we could only do it," he sneered. "But the age for that game is past. There is no chance of hocussing a horse, or laming him, or bribing a stable boy, or squaring a jockey. That was all very well in the old days, when meetings were few and far between, and we hadn't got an enlightened Press that watches everything as a cat watches a mouse. It's no use wasting time over idle dreams of that sort, Foster. Poor as he is, Sir George wouldn't even hear of such a thing."

"Think not?" Foster asked. "Well, I believe myself that every man has his price. I have never found anything to the contrary. I thought you were a fool to come down here at all. I thought you were a fool to allow yourself to be fascinated by that girl, but now I begin to see a way of turning it to account. I don't suppose she'll marry you. I never thought she would."
