"Splendidly," Phillips replied. "I have been far more fortunate than I anticipated. We will get some fun out of Copley and Foster yet. From your point of view I daresay you may think I am wrong. But I mean to make money out of this. I will expose Copley and fill my purse at the same time. You wonder what I am driving at? Can you manage to stay here over to-morrow?"

"I think so," Fielden said.

"That's good. In that case we can push our investigations farther and, with any luck, before the week is out we shall not only know where Copley gets his money, but how he makes it. Of course, we know that he doesn't even begin as a millionaire; we know that he is an unscrupulous adventurer. But he has the command of ready money, and we wish to know how he makes it. As a matter of fact, I know that already. But there are a few weak points in my case, and we can't make a definite move till these are cleared up. Now I want you to have dinner with me in my lodgings. I told my landlady I might have a friend staying with me, and she will be ready to put a bedroom at your disposal."

"Why this mystery?" Fielden asked.

"Oh, it is no mystery. I only want to interest you. After dark we shall indulge in a little quiet burglary, that is, if you don't object."

"It is not an alluring prospect," Fielden said.

"Of course it isn't," Phillips agreed. "But when you are dealing with scoundrels it is necessary to use their own weapons. I presume you are as interested as I am in the exposure of Copley and Foster and all their methods."

"Up to the hilt," Fielden said between his teeth. "Poor as I am, I would give all I possess to bring that about. I would give five years of my life to manage that between now and Derby Day. And if necessary I can find some money. I am better off than I expected, but I intended to keep the money for a start in life later. Still, if you want it and will promise to put it to a good use, I will give you every farthing cheerfully. You have only to say the word."

Phillips chuckled.

"Oh, there's no occasion to do that, sir," he said. "Keep the money in your pocket. I shall have enough and to spare before long. I mean to drag Copley's plunder from between his teeth. I will take all I can get from him, and when the time comes we shall drop a hint in the proper quarter, and there will be an end to Raymond Copley. Within three months you will see that man in gaol. You needn't be alarmed for Miss Haredale. She is as safe from that man as if she were the daughter of the King. I had better be going, because it is as well that we should not be seen talking together for too long. I have scribbled my address on the back of this card, and shall expect you about half-past seven."
