When an explosion rips across Hunstanton Beach on the north Norfolk coast, an abandoned Second World War bomb is assumed to be the cause...but is it? Could there be a connection with the new pier being built-and the increasingly bitter campaign to halt its construction? At the same time, DI Shaw and DS Valentine are on the hunt for an elderly female killer with a uniquely macabre method of despatch. And a 63-year-old Dutch engineer is missing, presumed drowned...but where is the body? All seemingly unrelated investigations - but in each case nothing is as it seems. To find the answers, Shaw must delve into the past, and a mystery that has remained unsolved for more than sixty years.
