Discover the unputdownable new historical thriller from Sunday Times bestselling author in which a brilliant detective must chase down a heartless murderer. That murderer is Adolf Hitler.

Munich, 1931.

A young woman is found dead in Adolf Hitler's apartment.

The official verdict is suicide. Detective Inspector Thomas Bauer knows it's murder.

The victim is Geli Raubal - Hitler's niece, prisoner, and secret shame. Within hours, Bauer's investigation is shut down. Witnesses are silenced. Evidence disappears.

As the Nazi movement gathers power, the truth must be kept hidden at all costs. Only Bauer dares to keep digging.

Decades later, historian Eleanor Robbins uncovers traces of a story erased from the record - a vanished investigation and proof of crimes buried for nearly a century.

The truth can change history.

But uncovering it might cost everything.
