September 1913. A young Pole suffering from tuberculosis arrives at Wilhelm Opitz’s Guesthouse for Gentlemen in the village of Görbersdorf, a health resort in the Silesian mountains. Every evening the residents gather to imbibe the hallucinogenic local liqueur and debate the great issues of the day: Monarchy or democracy? Do devils exist? Are women born inferior? War or peace? Meanwhile, disturbing things are happening in the guesthouse and the surrounding hills. Someone --- or something --- seems to be watching, attempting to infiltrate this cloistered world. Little does the newcomer realize, as he tries to unravel both the truths within himself and the mystery of the sinister forces beyond, that they have already chosen their next target.

In a remote Polish village, Janina devotes the dark winter days to studying astrology, translating the poetry of William Blake, and taking care of the summer homes of wealthy Warsaw residents. Her reputation as a crank and a recluse is amplified by her not-so-secret preference for the company of animals over humans. Then a neighbor, Big Foot, turns up dead. Soon other bodies are discovered, in increasingly strange circumstances. As suspicions mount, Janina inserts herself into the investigation, certain that she knows whodunit. If only anyone would pay her mind.
