The war with the Eastern Empire ended in stalemate some eighty years ago, thanks to Nall's 'Engine', a wizard-crafted weapon so powerful even the Deep Kings feared it. The strike of the Engine created the Misery - a wasteland full of ghosts and corrupted magic that now forms a No Mans Land along the frontier. But when Galharrow investigates a frontier fortress, he discovers complacency bordering on treason: then the walls are stormed, and the Engine fails to launch. Galharrow only escapes because of the preternatural magical power of the noblewoman he was supposed to be protecting. Together, they race to the capital to unmask the traitors and restore the republic's defences. Far across the Misery a vast army is on the move, as the Empire prepares to call the republic's bluff.

Most unusually for his times, Frantz was also a diarist. Drawing deeply on this exceptional and overlooked record that he kept for over forty-five years, The Faithful Executioner takes us deep inside his world and his thinking. But the picture that emerges is not of a monster. Could a man who routinely practiced such cruelty also be insightful, compassionate - even progressive?

Young Frantz enters the trade as the Apprentice, following in his father's footsteps. Later, as the Journeyman, he travels the roads of Franconia, learning to reconcile his desire for respectability with his violent work. After a lifetime working amid human cruelty, tragedy, injustice and simple misfortune as the Master in Nuremberg, Frantz has become a moralist and storyteller, the Sage. And, in the closing chapters of his life, retired now from his role as executioner, he is the Healer, running the large medical practice that he always viewed as his true vocation.

The Faithful Executioner is the biography of an ordinary man struggling to overcome an unjust family curse and a panorama of a Europe poised on the cusp of modernity, a world with startling parallels to our own.
