Leda Crannon knew perfectly well what effect the throb might have on Snookums’ brain, and when something cracked, she wanted to see what effect it might have on the behavior of the little robot. Like a hound after a fox, she followed him through the corridors of the ship.

Up companionways and down, in and out of storerooms, staterooms, control rooms, and washrooms Snookums scurried, oblivious to the consternation that sometimes erupted at his sudden appearance. At certain selected spots, Snookums would stop, put his metal arms on floors and walls, pause, and then go zooming off in another direction with Leda Crannon only paces behind him, trying to explain to crewmen as best she could.

If Snookums had been capable of emotion—and Leda Crannon was not as sure as the roboticists that he wasn’t—she would have sworn that he was having the time of his life.

Seventeen minutes after the throb had begun, Snookums rolled into Power Section and came to a halt. Something else was wrong.

At first he just stopped by the door and soaked in data. Mike’s muttering; the clipped, staccato conversation of the power crew; the noises of the tools; the deep throb of the ship itself; the underlying oddness of the engine vibrations—all these were fed into his microphonic ears. The scene itself was transmitted to his brain and recorded. The cryotronic maze in the depths of the ship chewed the whole thing over. Snookums acted.

Leda Crannon, who had lost ground in trying to keep up with Snookums’ whirling treads, came to the door of Power Section too late to stop the robot’s entrance. She didn’t dare call out, because she knew that to do so would interrupt the men’s vital work. All she could do was lean against the doorjamb and try to catch her breath.

Snookums rolled over to the board where Multhaus was sitting and watched over his shoulder for perhaps thirty seconds. The crewmen eyed him, but they were much too busy to do anything. Besides, they were used to his presence by this time.

Then, in one quick tour of the room, Snookums glanced at every meter in the place. Not just at the regular operating meters, but also at the meters in the testing equipment that the power crew had jack-plugged in.

Mike the Angel looked around as he heard the soft purring of the caterpillar treads. His glance took in both Snookums and Leda Crannon, who was still gasping at the door. He watched Leda for the space of three deep breaths, tore his eyes away, looked at what Snookums was doing, then said: “Get him out of here!” in a stage whisper to Leda.

Snookums was looking over the notations on the meter readings for the previous few minutes. He had simply picked them up from the desk where one of the computermen was working and scanned them rapidly before handing them back.
