Ringing in the ears can come from too much alcohol, or a shot of dope, or a slap on the side of the head. Or a change in air-pressure. Farradyne had not been drinking nor taking the needle, but he had spent many years in an environment where the supply of air was important. He had become oversensitive to it. He sniffed automatically, the gesture of a man who has reason to suspect the quality of the air he is breathing. He shook his head. He did feel a bit light-headed. There was the bare trifle of a dull pain above his eyes and a sting in his nose. He sneezed and brought forth a dribble of blood.
Farradyne raced aloft; he could settle nothing standing in the workshop. The bulkhead door between the hold of the Lancaster and the passengers' section was closed. He pushed it and it opened with slight difficulty to let a blow of air hit his face. He grunted in puzzlement. Any change in air-pressure in any part of the ship should have started a clangor of the puncture alarm, a racket loud enough to waken the dead.
He went through the stateroom corridor and listened carefully as he went. Some rooms were silent and others sounded like the song of the cross-cut saw working its way through a burl of maple. There were gradations of snores between these extremes. Nothing that a suspicious man could put his finger on. He did not pause in the salon, which was silent and darkened, but not completely black. There was nothing out of the way here.
In fact the only thing that was out of line was the queer fact that the ship was silent when the alarm should have been sounding. He went up to the control room.
Lamps told him the story in a series of quick appraisals, because of some long-forgotten genius that had insisted that whenever possible, warning devices should not be fused, should not be turn-offable and should not be destructible. The Lancaster was a fine ship, designed well, but a frontal attack on a panel with metal cutting tools made the exception to the "whenever possible" part of the design of warning signals.
The ship's bell-system had been opened like a tin can.
But the pilot lamp system was strung here and there behind the panels and it would have taken a major overhaul to ruin it; the saboteur would have spent all night opening cans instead of doing his dirty work. Farradyne should have been asleep, then he would not have noticed the blaze of lamps.
They told him the tale in a glance. The low-pressure portion of the ship was down in the pile-bay, and the reason was that one of the scuttle-doors was open. The pressure in the reaction-mass bay was low, and now that Farradyne had come aloft, the pressure in the upper levels was as low as the reaction-mass bay. As he watched, another one of the scuttle ports swung open and its warning lamp flared into life.
Farradyne went into action. He ripped open the cabinet that held his space-suit and clawed the thing from its hook. He started down the stairway on a stumbling run, getting into the suit by leaps, jumps and pauses. He realized that he could have moved faster if he stopped to do one thing at a time, but his frantic mind would not permit him to make haste slowly. So he stumbled and he fell against the walls, and the tanks of his back rapped against his shoulder-blades, and the helmet cut a divot out of the bridge of his nose. Luckily it did not make him bleed, but it hurt like the very devil.
He zipped up the airtight clotures by the time he reached the little workshop and he ducked in there to get a weapon of some sort. He reached past the hammer, ignored the obvious chisel because it was not heavy enough, even though it was sharp, and picked up a fourteen-inch half-round wood-working rasp. He hefted it in his gloved hand and it felt about right.
