Captain Francis Newcombe sprang for the electric-light switch, and turned off the light. There was Locke now! The pound of the ship, the noise of the storm, had of course deadened any sound in the passageway, but he could hear the other at the sitting room door. There was no time to replace the despatch case and push the trunk back under the couch, let alone attempt to lock either one. The man was coming now—across the other room. Captain Francis Newcombe laid the despatch case silently down on the floor, opened the door as silently, stepped out into the passageway and ran noiselessly along it.
He reached the door of his own cabin. His excursion to Locke's cabin and the evidence of intrusion he had been forced to leave behind him had put an end to any more "prowling" on his part to-night. Locke would probably kick up a fuss. There would be a very strict search for "prowlers!" He snapped his jaws together viciously. That did not at all please him. He would very much prefer that the would-be assassin should have another opportunity of showing his hand, that the man would be inspired to make a second attempt. He, Captain Francis Newcombe, would be a little better prepared this time!
He pushed open the door of his cabin cautiously—and for an instant stood motionless, a little back from the threshold, and at one side. There was always the possibility, remote though it might be, that while he had been out searching for the other, the man had slipped inside and, waiting, had made of the cabin a death trap which he, Captain Francis Newcombe, was now invited to enter. It was not likely. It would require a little more nerve than the firing of a shot through the window, and then running away. But, for all that, having failed the first time, the other might be moved to take what might possibly be considered more certain measures on the next attempt. And in that case—No; the cabin was empty! The light from the passageway, filtering in through the open door, showed that quite plainly.
Captain Francis Newcombe stepped inside, and, before closing the door, looked curiously over the woodwork near the door and on a line with the window. Yes, there it was! The writing on the wall! The bullet had splintered a piece of the wall panelling, and had embedded itself in the wall a little to the right of the door casing.
He closed and locked the door now, shutting out the light, and, with his revolver in his hand, sat down in the darkness, out of direct range himself, but where he could command the window. It was a bit futile. He was conscious of that. But there was always the possibility of the man's return, and there was no other possibility that promised any better—or, indeed, promised anything at all.
His mind began to weigh, and sift, and grope as through a maze, battling with the problem again. Not Locke! He was rather definitely prepared to set Locke apart from everybody else on board the ship, and say that it was not Locke. Who, then? Who had any—
He straightened up, suddenly even more alert. There was some one out in the passageway now—some one outside his door. There came a low, quick rap.
"Who's there?" demanded Captain Francis Newcombe sharply.
Locke's voice answered:
"It's Locke. May I come in?"
