Lady Evelinn, endowed with the gift of a medium, comes to spend her summer holidays with her grandmother at a manor house. But the idyll is broken by a string of mysterious incidents: attacks occur in the surrounding area against girls, and the victims claim they encountered an invisible criminal. In her search for the truth, Evelinn is drawn into a dangerous investigation where mysticism and reality intertwine. A mysterious investigator from the capital gets involved—his behavior raises questions no less than the crimes themselves. And an unexpected encounter with what’s allegedly a vanished werewolf adds new mysteries. Evelinn must not only solve the mystery of the invisible criminal, but also accept her medium gift—one that can become either her greatest advantage or a lethal danger. In a world where ghosts are real and old legends come back to life, she’ll have to learn to trust not only herself, but also her partner from the capital. An atmospheric detective story with elements of mysticism and fantasy, where every plot twist keeps you on edge until the very last page.
