I came out of these thoughts to find that we were following the avenue with part of which I had made myself so familiar ten days before. I began to ask myself if Cantyre had a motive in bringing me this way. The houses were thinning out. Vacant lots became frequent. I noted the southern limit of my pacings up and down on that strange midnight. Cantyre slowed the pace perceptibly. My heart thumped. If he accused me of anything, I was resolved to confess all.

As we passed one particular vacant lot, a tangle of nettle, fireweed, and blue succory, I noticed that Cantyre’s gaze roamed round about it, to the neglect of the machine. We had slowed down to perhaps ten miles an hour.

“Do you know whose house that is?” he asked, suddenly.

But I refused to betray myself before it was necessary.

“Whose?” I riposted.

“Sterling Barry, the architect’s.”

The machine almost stopped. He looked the façade up and down, saying, as he did so: “It’s closed for the season. They left town a few days ago. Barry’s bought the old Hornblower place at Rosyth, Long Island.”

To my relief, we sped on again; but I was not long in learning the motive behind his interest.

Chiefly for the sake of not seeming dumb, I said, as we got into the country, “You and Ralph Coningsby are by way of being great friends, aren’t you?”
