As World War II ends, a killer’s game begins.

In the final days of the Nazi regime, with the historic city of Dresden on the brink of destruction, terrifying rumors spread about the Fright Man, a demonic killer who exploited the cover of a nighttime air raid siren to mutilate and kill a young nurse. Just as seasoned detective Max Heller begins investigating, the Fright Man kills again…

The investigation seems hopeless. Desperate refugees flood the streets, all of Heller’s resources are depleted, and his new boss is a ruthless SS officer. And like so many others, Heller and his wife, Karin, survive on meager rations while fearing for the lives of their sons at the front. But as tensions mount and enemy firebombs decimate the city, dangerous new clues come to light—and the determined Heller pursues a violent and twisting path to unmask a monster.
