Promoted to detective inspector, Patrick Petrella now finds himself in a London borough close to the Thames. In these short stories he has to deal with arson, blackmail, fraud, forgery, and murder. The Thames is a focus for some of the stories, as it is convenient for the dumping of a body and for arrivals from abroad. Written with Michael Gilbert’s eye for detail and knowledge of police procedures, along with the suspense that is his hallmark, this is a fitting accompaniment to the stories contained in the other Petrella volumes.
