No, did he return at once, the plan was quite feasible. Seeing him there so soon after his departure, they could do nothing but accept his reasons, and that especially if he returned quite openly with no thought of concealment.
But oh how he hated to go back! He put his hand on the rough stuff of Jabez's jersey, listened for a moment to the regular, consoling breathing of the sea, sniffed the roses and the cool, gentle night air, then said:
"Well, come along, Jabez; show me how to get back."
As they moved round to the door the thought came to him as to whether he had given the elder Crispin and his two nasty servants time enough to retire up to their part of the house. A difficult thing that, to hit the precise medium between too lengthy a wait and too short. He could not remember exactly what Dunbar had said as to that.
"Do you think I've waited long enough, Jabez?" he asked.
"Well, if you'd forgotten something, sir," said Jabez, "you'd want to be sure of finding it before the house is sleeping. They don't bolt this door, sir," he continued in a whisper, "because Mr. Crispin don't like to be bolted in. His fancy. After half-past one or so one of they Japs is around. It's just their hour like from half-past twelve to half-past one that I have to watch this part of the house extra careful. Yes, sir," he added as he turned the key in the lock and pushed the door quietly open.

The hall was very dark. From half-way up the staircase some of the starlit evening scattered mistily through a narrow window, splintering the boards with spars of pale milky shadow.
A clock chattered cluck-cluck-spin-spin-cluck close to Harkness's ear. Otherwise there was not a sound anywhere. He reflected that several things had been forgotten in his talk with Dunbar; one that there would, in all probability, be no light in the upper passage. How was he then to find the younger Crispin's door, or to see whether or no there were that piece of paper under Mrs. Crispin's? Secondly, it would be in the room on the ground floor where he had had his strange interview with the elder Crispin that he must see the younger, because, of course, that gloomy creature, dumb though he appeared to be, would be at least aware that Harkness had never ventured into the upper floor at all and could not therefore have left his gold match-box there. On the whole, this would be the better for Dunbar's plan, because it would lead the younger Crispin all the farther from his wife's door. But there were, at this point, so many dangers and difficulties, so many opportunities of disaster, that in absolute desperation he must perforce go forward.
He was aware that for himself now the easiest fashion would be to persuade himself that he had indeed lost his match-box and was returning to secure it. He hesitated on the bottom step of the stairs as though he were wondering what he ought to do, how he might find the tiresome thing without rousing the whole house.
