"You might as well," I told him. "She talked and we listened for at least twenty minutes. Then we both questioned her. In a question-and-answer session like that the vital points are apt to get a little blurred."
"Well, we know she did something no one has ever done before—stowed away on a Mars' ship. I'd have said it couldn't be done ... and so would you, I'm sure, because you're as familiar with the inspection routine as I am. You passed through it. No one could possibly get inside a Mars' rocket without a Board clearance and a personal, ten-point identification check every step of the way. In other words, you can't just ascend the launching pad, be whisked up to the passenger section and walk right in. There's only one way you can get inside without passing the four inspection points, with machines X-raying you from head to toe."
"I know," I said. "It was a damn clever stunt."
"It was more than a stunt. It was an achievement on the creative genius level. It took planning and foresight. And ... luck. A great deal of luck. But that doesn't detract from the brilliance of it. She found out that we were installing a new cybernetic robot, to replace one that had developed electronic fatigue and had to be removed for repairs and a long rest. And she knew that we wouldn't X-ray a robot or subject it to any of the usual tests. It would just be wheeled right in."
Littlefield paused an instant, then went on. "She knew there was plenty of room inside a cybernetic robot that large, between the tiers of memory banks and all the other gadgetry, for the carrying out of what she had in mind—a stowaway gamble that was almost sure to succeed. She provided for her comfort during the long trip in half-dozen ingenious ways, as we know, and made sure that the food concentrates she took along were high in essential proteins.
"She knew, of course, that she couldn't stay inside the robot without coming out at all. She'd have to emerge occasionally, if only to ease the psychological strain. But she used good judgment and only emerged when she was absolutely sure that it would be safe."
"But once she didn't," I said.
"Once she didn't. Once she felt she couldn't stand the tensions that were building up in her any longer and she took a chance and came out when she wasn't sure the Chart Room would be deserted. You told me you thought it was never left unguarded. Well ... that isn't strictly true. There's a built-in security alert system in all of the robots and we can risk leaving it unguarded for a few minutes, when every member of the crew is needed elsewhere, to take care of some particularly troublesome space headache. That's what we call the small and seldom very serious emergencies which are always arising in a sky ship this large."
"But if she heard someone moving about ... she must have been crazy to emerge," I said.
"That's just it. She wasn't sure she heard anyone. In fact, she was almost sure it would be safe to emerge. She'd learned to trust her instincts, and the silence was almost unbroken. Just once she thought she heard a slight sound, but she put it down to the tension that was building up in her. She felt she had to emerge."
