On the first night of the Blitz, a corpse is discovered in a van in the back streets of West Ham. Detective Inspector John Jago recognizes the dead man as the Local Justice of the Peace. But then a German bomb obliterates all the evidence.
Jago soon discovers the dead man held many secrets, some reaching back to World War I. A lot of people wished him dead, and an air raid is a good time to conceal a murder.
