1660: Winter has settled thick over a sleepy village in the Bavarian Alps, ensuring every farmer and servant is indoors the night a parish priest discovers he's been poisoned. As numbness creeps up his body, he summons the last of his strength to scratch a cryptic sign in the frost.

Following a trail of riddles, hangman Jakob Kuisl; his headstrong daughter Magdalena; and the town physician’s son team up with the priest’s aristocratic sister to investigate. What they uncover will lead them back to the Crusades, unlocking a troubled history of internal church politics and sending them on a chase for a treasure of the Knights Templar.

But they’re not the only ones after the legendary fortune. A team of dangerous and mysterious monks is always close behind, tracking their every move, speaking Latin in the shadows, giving off a strange, intoxicating scent. And to throw the hangman off their trail, they have ensured he is tasked with capturing a band of thieves roving the countryside attacking solitary travelers and spreading panic.

Delivering on the promise of his international best seller The Hangman’s Daughter, Oliver Pötzsch takes us on a whirlwind tour--once again based on prodigious historical research into his own family tree--through the occult hiding places of Bavaria’s ancient monasteries, bringing to life an unforgettable compassionate hangman and his tenacious daughter, painting a robust tableau of a 17th-century Bavaria still negotiating the lasting impacts of war, and quickening our pulses with a gripping, mesmerizing mystery.
