This is the second book in the Isaac Asimov’s Robot City series, and follows on directly from Odyssey. In fact, it follows so closely that it feels like it should be part of that earlier book.
I preferred this book to the first in the series, I suspect because it didn’t need to use a random unexplained change to escape a dying plot line (which is what I felt happened about a third of the way through the first book). This book does feel a little juvenile though, but I forgive it.
A man and a woman stranded in a city of robots are the only logical suspects in a case of murder and their identities and the name of the murderer are two of the mysteries to be solved
