The Robot Who Wanted To Know by Harry Harrison - Did he have a right to feel this way? was this really forbidden by law—this wonderful frightening emotion!
That was the trouble with Filer 13B-445-K, he wanted to know things that he had just no business knowing. Things that no robot should be interested in—much less investigate. But Filer was a very different type of robot.
The trouble with the blonde in tier 22 should have been warning enough for him. He had hummed out of the stack room with a load of books, and was cutting through tier 22 when he saw her bending over for a volume on the bottom shelf.
As he passed behind her he slowed down, then stopped a few yards further on. He watched her intently, a strange glint in his metallic eyes.
