He still felt dizzy, and his head was aching a little, but he moved quickly through the darkness, his faculties heightened by an intensity of purpose which enabled him to find the companionway without colliding with obstacles or taking a wrong turn. Up the stairway he climbed, still clutching the knife, prepared for a possible second encounter with its original owner. An attempt to regain the knife by trickery and stealth would not have surprised him. In fact, it was not at all difficult for him to picture a silent form flattened against the stair-rail, waiting for just the right moment to come hurtling toward him out of the darkness. For a moment, as he ascended, the strain became almost unendurable. Then the darkness dissolved above him, and he was advancing toward the captain's cabin through the narrow passageway which he had spanned with his arms spread wide. He did not stop to span it this time. He emerged into the cabin and stood for an instant blinking in the sudden light. The cabin was still deserted. It was anybody's guess where the captain had gone or when he would be returning, and Corriston decided not to wait. He walked to the door, opened it and stepped out into the general passenger cabin. No one saw him immediately. There were several passengers fairly close to him, but they were being attentive for the moment to the words and gestures of a tall, dignified looking man with observant brown eyes, a ruddy complexion, and gold braid on his shoulders. The tall man was Captain John Sanders. "I'd be a hypocrite and a liar if I said there was no justification for alarm," Sanders was saying, in a voice loud enough to carry to where Corriston was standing. "Strict regulations prescribe that sort of thing. But it's no way for a captain to keep the respect of his passengers." Corriston felt himself stepping forward before he even thought about it. But he halted abruptly when the captain said: "There's a murderer on the loose aboard this ship. You may as well accept that fact right now. Each of you has to be on his guard. It's only right and proper that you should keep your eyes and ears open, and _stay_ worried. If you do, our chances of catching up with him before the ship berths should be reasonably good." The captain paused, then went on quickly: "We'll get him eventually. You can be sure of that. He'll never get past the inspection each of you will have to undergo when we reach the Station. But if we catch him before we reach the Station, you'll be spared an investigative ordeal distinctly on the rugged side." Corriston was suddenly aware that he was being stared at. Everyone was staring at him. "My God!" the Captain cried out, staring the hardest of all. "Where did you get that wound? Who attacked you? And what were you doing in my cabin?" Corriston walked up to the Captain and said in a voice that trembled a little. "May I talk to you privately, sir? What I have to say won't take long."
