"I had my keys to the safe an' the magazine when I was aboard last trip," he said. "They was with me when we went on the ice. An' I hung on to 'em. Allus thought I might have a chance to use 'em ag'in." The strong room of the _Karluk_ was a narrow compartment, heavily partitioned off from the galley and the corridor. There was a lamp there, and Rainey lit it while Lund closed the door behind them. The magazine was an iron chest fastened to the floor and the side of the vessel with two padlocks, opened by different keys. It was quite empty. "Thorough man, Carlsen," said Lund. "Prepared for a show-down, if necessary. Might have put 'em in the safe. Wonder if he changed the combination? I bet Simms didn't, year in an' out." He worked at the disk and grunted as the tumblers clicked home. "It ain't changed," he said. "No use lookin' here." But he swung back the door and rummaged through books and papers, disturbing a chronometer and a small cash-box that held the schooner's limited amount of ready cash. There was no sign of any cartridges. "We'll tackle Carlsen's room next," he announced. "I don't suppose you looked between the bunk mattresses, did you?" "I never thought of it," said Rainey. "I didn't imagine there would be more than one." "I've got a hunch you'll find two on Carlsen's bunk. An' the shells between 'em. He kep' his door locked when he was out of the main cabin an' slep' on 'em nights. That's what I'd be apt to do." As they came into the main cabin Rainey caught Lund by the arm. "I'm almost sure I saw Carlsen's door closing," he whispered. "It might have been the shadow." "But it might not. Shouldn't wonder. One of 'em's sneaked in. Saw the cabin empty, an' figgered we'd turned in. While we was in the strong-room." He took the automatic from his pocket and went straight to the door of Carlsen's room. It was locked or bolted from within. "The fool!" said Lund. "I've got a good mind to let him stay there till he swallers some o' the drugs to fill his belly." He rapped on the panel with the butt of the gun. "Come on out before I start trouble." There was no answer. Lund looked uncertainly at Rainey. "I hate to start a rumpus ag'in," he said, jerking his head toward the skipper's room. "'Count of her. Reckon he can stay there till after we've buried Simms. He's safe enough." Rainey was a little surprised at this show of thoughtfulness, but he did not remark on it. He was beginning to think pretty constantly of late that he had underestimated Lund. The giant's hand dropped automatically to the handle as if to assure himself of the door being fast. Suddenly it opened wide, a black gap, with only the gray eye of the porthole facing them. Lund had brought up the muzzle of his pistol to the height of a man's chest, but there was nothing to oppose it. "Hidin', the damn fool! What kind of a game is this? Come out o' there."
