Inspired by the remarkable life of Dorothy Peto, the Metropolitan Police’s first female superintendent.

During war, death isn’t only found on the battlefield …

It’s 1915 and war continues to rage across Europe, but at home in England, the members of the Women Police Volunteers are more accepted and their numbers continue to grow. However, founding member, Dorothy Peto is frustrated at being consigned to office duties and training recruits. Then, early one morning, her friend Margaret finds a dead body in the garden next door.

When they discover the wealthy victim’s will is missing, the list of possible suspects grows. Once again, Dorothy finds herself working alongside the inscrutable Inspector Derwent. Determined to prove herself a worthy investigator even as she battles personal loss and feuding friends, Dorothy gains the trust of witnesses, and pits her wits against a killer who may not stop if threatened.
