Isaac Asimov's Robot City (Electronic book text)

Derec wakes up in a survival pod, on an asteroid, amidst a colony of mining robots minus his memory. He escapes from them only to land up in the clutches of another bunch in Robot City. Derec has Katherine for company-the only other human there, who exasperatingly enough does nothing for his amnesia. As robots abide strictly by the law of not harming humans, a dead man narrows the field of suspicion to the two of them, for which they are promptly imprisoned. Will Derec regain his memory and freedom is what remains to be seen?
