Or had the dead man not had it in his possession? Had it been slipped into his pocket by some one else? But one could not slip anything of the weight and bulk of a service revolver into a man's pocket unknown to him. No, not a living man, but — it could have been done after the knife-thrust. But why? Why? No solution, however far fetched, presented itself to him. He took the dagger out of its wrappings, and considered it through the microscope, but could mesmerize himself into no hopeful state over it. He was stale. He would go out and walk a bit. It was just after five. He would go down to the Woffington and see the man who had been doorkeeper at the pit last night.

It was a fine still evening with a primrose sky, and London was painted against it, in flat washes of a misty lavender. Grant sniffed the air appreciatively. Spring was coming. When he had run the Levantine to earth, he would wangle some leave — sick leave, if he couldn't get it any other way — and go fishing somewhere. Where should he go? You got the best fishing in the Highlands, but the company was apt to be darned dull. He would go fishing in the Test — at Stockbridge, perhaps. Trout were poor sport, but there was a snug little pub there, and the best of company. And he would get a horse to ride there, and turf to ride it on. And Hampshire in spring — !

So he speculated, walking briskly along the Embankment, on things far removed from the business on hand. For that was Grant's way. Barker's motto was: "Chew it over! Chew it over continually, sleeping and waking, and you'll find the kernel that matters." That was true for Barker but not for Grant. Grant had once retorted that when he had chewed to that extent he couldn't think of anything but the ache in his jaws, and he had meant it. When something baffled him he found that if he kept on worrying it, he got no further, and lost his sense of proportion in the process. So when he came to a dead stop he indulged in what he called "shutting his eyes" for a little, and when he «opened» them again he habitually found a new light on things that revealed unexpected angles and made the old problem a totally new proposition.
