Bed lodgers - you used to find them in every large city. They were poor people who could only afford to rent beds, not whole apartments for their families. And sometimes, in very old buildings, where the apartments are very humble and the rents are very low, they're still with us: People who sleep in your bed and eat at your table when you're not at home. Or can you think of a better explanation for why your bed never stays made and your room always looks messy? And why the fresh box of breakfast cereal your mother just bought yesterday is already empty and nobody knows whose toothbrush is whose? Albrecht and Luise Drewitz from Berlin learn the hard way what bed lodgers are and how not to make them angry - which, by the way, is never a good idea. The Bed Lodgers is a tale of ghosts and fantasy from the heart of Europe's liveliest city.
