Shelley Puhak. The Blood Countess: Murder, Betrayal, and the Making of a Monster. New York, Bloomsbury Publishing, 2026.

There have long been whispers, coming from the castle; from the village square; from the dark woods. The great lady-a countess, from one of Europe's oldest families-is a vicious killer. Some even say she bathes in the blood of her victims. When the king's men force their way into her manor house, she has blood on her hands, caught in the act of murdering yet another of her maids. She is walled up in a tower and never seen again, except in the uppermost barred window, where she broods over the countryside, cursing all those who dared speak up against her.
