She was soon back, obviously still perplexed by his request but with the information he wanted.
"The cabins are all on the second cabin-deck, like yours and mine," the girl told him. "That of Jurk Usk is two doors off the main corridor, toward the stern. Kark Al, the Martian, is three doors beyond that. And the cabin of the young Earthman who was poisoned is directly opposite the Martian's. You know where the rest are."
"I know," Crane said swiftly. "You've helped me a lot, Lalla Dee. I want you to go back up now and forget all about this, and no matter what happens to me, don't you say anything that will get you mixed up in this affair."
"Norman, you sound as though something awful might happen to you," she told him distressedly. "What is it?"
"I'll be all right," he repeated "And you're a swell girl, Lalla Dee."
She left and Crane paced the floor, seething with excitement. If he could just get to Jurk Usk's cabin…
He waited impatiently for the coming of the ship's night. When finally the lights had been turned off and the passengers had retired, and the whole craft silent except for the occasional passing step of a sailor and the throbbing of the ventilators, Rab Crane began to act. First he removed his shoes and sox.
Then he twisted with all his strength at one of the metal posts that supported his bunk, until he tore it loose. With this short, thick club in his hand, he climbed upon the now shaky bunk and reached up toward the grating of the ventilator-tube.
The tube was almost two feet across, a round pipe connected with the main ventilation system which dispersed oxygenized fresh air constantly to every room in the ship. Crane inserted his club in the grating and pried. The grating came loose with a little snap, and he poised, listening. But, apparently, no one had heard.
He stuffed the club into his trouser band and drew himself up into the ventilating tube. He got one shoulder in, then the other. The tube was a terribly tight fit but he inched steadily forward in it. In his face beat the constant flood of fresh, tangy air, and in his ears throbbed the distant pumps. Soon the tube opened into a vertical pipe, a somewhat larger one leading up to the decks above. Crane climbed slowly up this, bracing himself with bare hands and feet against the smooth sides.
