get reconstruction going in a matter of minutes when the brain, the anatomy's most perishable component, was involved. And in some cases he had known, the memories were never fully restored. Why couldn't it have been a tumor? A deficiency disease? A nervous breakdown? Insanity.... There was nothing the medocenter couldn't handle. Its machines were right there on the ship, ready to be used—but Karen had to fall down the ventilator shaft, opening the door and walking into it as if it were her bedroom, and falling all the way down and breaking half the bones in her body. And he had found her too late. Hours too late. "Too late," he said, and he nodded his head in agreement.

But now there would always be Karen. He should have told them she walked in her sleep. But the Medical Examiners would have shrugged as they had with everything else he had told them. The medocenters would take care of it. You couldn't cure sleepwalking
