"I am not losing sight of that fact," said Quarles, "but I have little doubt it is the money."
As we drove back to Chelsea the professor was silent, but when we were in the empty room he began to talk quickly.
"I am puzzled, Wigan. Before we went out I was saying some one was out for money, and the letter Sir Michael has received proves it. We were engaged upon a negative argument, and I should have gone on to show why it was unlikely Cayley had had anything to do with the affair. I confess that his sudden appearance to-night tends to knock holes in the argument I should have used. He comes from Paris, the money is to be paid to the Credit Lyonnais, Paris. He is keen that the money should be paid, had evidently been persuading Sir Michael that it ought to be paid. This tends to confuse me, and I cannot forget Zena's remark about the girl's age and that this is not an ordinary kidnaping case. If Cayley had met her on the terrace she would naturally stroll away with him if he asked her to do so. At a safe distance from the house he, and a confederate, perhaps, may have secured her."
"But why?" I asked.
"He may want a quarter of a million of money and yet have no desire to marry. It is a theory, but unsatisfactory, I admit. One thing, however, we may take as certain. Eva Wilkinson was not driven away in that car. We have no news of any suspicious car being seen in any other direction, nor of any suspicious people being seen about, and it seems obvious that a false trail was laid for us. Wigan, it is quite possible that the girl never left Whiteladies at all, that she is hidden there now, in fact. Doesn't the disappearance of that coat and skirt tend to corroborate this? She was in evening dress at the time. It would be natural to get her another dress."
"That would mean confederates in the house," I said.
"Exactly. This girl Perry, perhaps, in league with her lover, the gamekeeper; or it may be Mrs. Reville herself. We are going down to Whiteladies to-morrow to try and find out, and we are going circumspectly to work, Wigan. You shall go to the house in the ordinary way, while I stroll across to the ruins. They are a likely hiding place. It will be dark, and I may chance upon some one keeping watch. In a few words you can explain our idea to Sir Michael, and then, without letting the servants know, you can come and find me in the ruins."
It was nearly dark when we arrived at Whiteladies on the following day, and as arranged, I left Quarles before we reached the lodge gates—in fact, helped him over a fence into the park before I went on to the house alone. Near the front door I found Mrs. Reville giving a couple of pug dogs a run. She told me Sir Michael was expecting me, and led the way into the hall.
"I think he is in the library," she said, and opened a door. "Oh, I am sorry, I thought you were alone, Sir Michael. It is Mr. Wigan."
He called out for me to enter. He was standing by a writing table, talking to a young farmer, apparently a tenant on the estate because Sir Michael was dismissing him with a promise to consider certain repairs to some outbuildings. As the farmer passed me on his way to the door Sir Michael held out his hand.
