* * * The cargo lock on the storage deck had two inner doors. The one which opened into the side of the vault hall was built to allow passage of the largest chunks of freight the _Queen_ was likely to be burdened with; it was almost thirty feet wide and twenty high. The second door was just large enough to let a man in a spacesuit climb in and out of the side of the lock without using the freight door. It opened on a tiny control cubicle from which the lock's mechanisms were operated during loading processes. [Illustration] Gefty let Kerim and himself into the cubicle from one of the passages, steered the girl through the pitch blackness of the little room to the chair before the control panel and told her to sit down. He groped for a moment at the side of the panel, found a knob and twisted it. There was a faint click. A scattering of pale lights appeared suddenly on the panel, a dark viewscreen, set at a tilt above them, reflecting their gleam. Gefty explained in a low voice, "Left side of that screen covers the lock. Right one covers the big hall outside. No lights in either at the moment, so you don't see anything. Only way the cargo door to the hall can be opened or closed is with these switches right here. What I want to do is get the janandra into the lock, slam the door on it and lock down the control switches. Then we've got it trapped." "But how are you going to get it to go in there?" "No real problem--I'll be three jumps ahead of it. Then I duck back up into this cubicle, and lock both doors. And it'll be inside the lock. You have the picture now?" Kerim said unsteadily, "I do. But it sounds awfully risky, Gefty." "Well, I don't like it either," Gefty admitted. "So I'll start right now before I lose my nerve. As soon as I move out into the vault hall, the lighting will go on. That's automatic. You watch the right side of the screen. If you see the janandra coming before I do, yell as loud as you can." He shifted the two inner door switches to the right. A red spark appeared in the dark viewscreen, high up near the center. A second red light showed on the cubicle bulkhead beside Gefty. Beneath it an oblong section of the bulkhead turned silently away on heavy hinges, became a door two feet in thickness, which stood jutting out at a right angle into the darkness of the cargo lock. A wave of cold air moved through it into the control cubicle. On the screen, another red spark appeared beside the first one. "Both doors are open now," Gefty murmured to the girl. "The janandra isn't in the vault hall or the lighting would have turned on, but it may have heard the door open and be on its way. So keep watching the screen." "I certainly will!" she whispered shakily.
