Suspicion — Mike McQuay

BEYOND AURORA AWAITS A BRAVE NEW WORLD...OF ROBOTS

A man without memory, stranded in a city of robots gone wild. At his side, a woman who claims to know who he is, but who refuses to tell him. On a planet whose other inhabitants are entirely robotic, these unwilling allies are the only logical suspects in a case of murder.

The young man calls himself Derec; she calls herself Katherine. Their real identities, and the name of the murderer, are just two of the astounding mysteries that surround you in the fantastic streets of Isaac Asimov's Robot City.
