A gripping historical novel about an unusual woman Frankfurt, 1462: When the widowed furrier Wöhler learns that his only daughter Sibylla has died far from home, he suffers a fatal heart attack. The only witness is the washerwoman Martha. She seizes the opportunity, conceals Sibylla's death and puts her own daughter Luisa, who has always looked a lot like Sibylla, in her place. Luisa is happy to no longer be a laundress, but the fear of being exposed never leaves her. When she falls in love with the doctor Isaak Kopper, she gets into trouble. For the rules of the guild dictate that she must marry a master if she wants to keep the furrier's trade. How will she decide?
