“The best in England, Mr. Holmes. I should know, if anyone does. Now, I’ll be plain with you, for I know you are gentlemen of honour and that it won’t go beyond the room. Sir Robert has got to win this Derby. He’s up to the neck, and it’s his last chance. Everything he could raise or borrow is on the horse⁠—and at fine odds, too! You can get forties now, but it was nearer the hundred when he began to back him.”

“But how is that if the horse is so good?”

“The public don’t know how good he is. Sir Robert has been too clever for the touts. He has the Prince’s half-brother out for spins. You can’t tell ’em apart. But there are two lengths in a furlong between them when it comes to a gallop. He thinks of nothing but the horse and the race. His whole life is on it. He’s holding off the Jews till then. If the Prince fails him he is done.”

“It seems a rather desperate gamble, but where does the madness come in?”
