"During an endless Covid lockdown in which everybody wears a mask and needs a haircut,Eddie’s wife is certain that he has been supplanted by an imposter. She hires a detective, the square-jawed Royler Boom, to solve the mystery. What follows — interspersed with Campbell’s trademark wry anecdotes, dreams, parodic pastiches, and pandemic peccadilloes — is a thrilling investigation that builds to a car chase and a violent conclusion. The author cunningly passes this off as another piece of autobiography."
