A Traitor in Whitehall: A Mystery (Hardback original)

Evelyne Redfern's family specialises in notoriety. Her father is Sir Reginald Redfern, a feckless, louche second son of an English baron, and her late beloved mother was a glamorous French party girl.

Their disastrous marriage ended in divorce and a very public custody battle over nine-year-old Evelyne that only resolved when Genevieve died three years later.

However, the damage was done, with the press dubbing Evelyne the 'Parisian Orphan' and making her the most notorious child in the world.

Years later in 1940, Evelyne is estranged from her father and working on the line at a munitions factory in wartime London.

Shortly after she settles into her new role as a secretary, one of the girls at the war rooms is murdered and Evelyne must use all of her amateur sleuthing expertise earned from years of reading mysteries to find the killer.
