I stood peering into the blackness, but in a few moments could hear no further sound. She had escaped, leaving me utterly mystified and wondering.

When, ten minutes later, I returned to Eric and described her silent departure, he said,—

“So you’re going to meet her in town—eh?”

“Yes, in secret, on Thursday night. She has made an appointment. She will leave Mason in Bournemouth, and then simply disappear. By the time Mason returns here the dead man will be in his coffin, therefore she won’t have any opportunity of identifying him.”

“But there’ll be a hue and cry after her. The police will think that something has happened to her.”

“Let them think. We shall pretend to make inquiries and assist them. In the meantime, with all these letters and things in our hands, we hold the trump cards.”

“If Tibbie knew that we had her letters, I wonder what she would say—how she would act?”

“She no doubt fears that they may fall into the hands of the police. That is why she is disappearing.”

“Of course. And for the present she must be allowed to remain in that belief,” Eric replied. “I wonder who the man Parham is? We must inquire. On Sydenham Hill are some rather nice houses. I once knew a rather pretty girl who lived in that neighbourhood, and used to take her for evening walks up the hill to the Crystal Palace.”

“Yes,” I said. “We must discover all we can about the dead man’s friends. We must also call and see the pawnbroker in the Fulham Road. He may be able to tell us who pledged the watch and ring. Indeed, we might get them out of pawn and see whether there are any remarks or inscription that will tell us anything.”
