At the Central Criminal Court, an eager crowd awaits the trial of Victoria Lamartine, an active participant in the Resistance during the war. She is now employed at the Family Hotel in Soho, where Major Eric Thoseby has been found murdered. The cause of death? A stabbing reminiscent of techniques developed by the Maquisards.

While the crime is committed in England, its roots are buried in a vividly depicted wartime France. Thoseby is believed to have fathered Lamartine’s child, and the prosecution insist that his death is revenge for his abandonment of Lamartine and her arrest by the Gestapo.

A last-minute change in Lamartine’s defence counsel grants solicitor Nap Rumbold just eight days to prove her innocence, with the highest of stakes should he fail. The proceedings of the courtroom are interspersed with Rumbold’s perilous quest for evidence, which is aided by his old wartime comrades.
