"Well," Dune said slowly, "my advice to you, Craven, is not to think too much about the whole business. A thing like that is certain to get on one's nerves—leave it alone as much as you can——"

"What a funny chap you are! You're always like that. As detached from everything as though you weren't alive at all. Why, I believe, if you'd committed the murder yourself you wouldn't be much more concerned!"

"Well, we've got to go on as we're made, I suppose, only do take my advice about not getting morbid over it. By the way, I see I'm playing against St. Martin's this afternoon."

"Yes. I thought at first I wouldn't play. But I suppose it's better to go on doing one's ordinary things. You're coming in to-night, aren't you?

"Are you sure you want me after all this disturbance?

"Why, of course; my mother's expecting you. Half-past seven. Don't dress." He raised his arms above his head, yawning. He was obviously better for the talk. His eyes were less strained, his body more alert. "I'm tired to death. Didn't get a wink of sleep last night—saw poor Carfax in the dark—ugh! Well, we meet this afternoon."

When the door closed Olva had the sensation of having been on his trial. Craven's eyes still followed him. Nerves, of course . . . but they had strangely reminded him of Bunker.

Olva had never been to Craven's house before. It stood in a little street that joined Cambridge to the country. At one end of the prim little road the lamps stopped abruptly and a white chalk path ran amongst dark common to a distant wood.

At the other end a broader road with tram-lines crossed. The house was built by itself, back from the highway, with a tiny drive and some dark laurels. It was always gloomy and apparently unkept. The autumn leaves were dull and sodden upon the drive; the bell and knocker upon the heavy door, from which the paint was worn in places, were rusty. No sound came from the little road beyond.
