An outlaw plowman falsely accused

An alchemist's virgin who is more than she seems

A fiendish murderer hiding in plain sight

Cathar country, (now) southern France, year: 1200.

When the woodcutter's only daughter is murdered, the citadel's bailiff tries to arrest Bertwoin the Plowman, who flees. To prove his innocence, the desperate plowman runs to a master alchemist and his professional virgin, Flowia, for help.

Bertwoin must find the brutal killer while the grieving woodcutter, the relentless bailiff, and righteous monks pursue him. His search for clues takes him to the corpse room inside an abbey, to a torture pit near the Devil's Doorstep, and to the accursed home of a heretic priest.

When monks capture Bertwoin, wily Flowia rescues him from the dungeon and hides with him where no one would think to look for them.

To save his own life and another life as precious as his own, Bertwoin must outwit the fiendish murderer. But now the sadistic killer also hunts them . . . and he knows how to find them.
