On the English Channel Island of Guernsey, Detective Inspector Ed Moretti and his new partner, Liz Falla, investigate vicious attacks on Epicure Films, an international production company shooting a movie about an Italian aristocratic family at the end of the Second World War. When vandalism escalates into murder, Moretti must resist the attractions of a glamorous American woman, consolidate his working relationship with Falla, and establish whether the murders on Guernsey go beyond the island.
