Charlotte Schleswig, the narrator of Liz Jensen's latest novel, supports herself and the lumpen Fru Schleswig (who may or may not be her mother) as a prostitute in 1890s Copenhagen. While she is no small success at the trade, she leaps at a new job opportunity for herself and Fru Schleswig, as cleaning ladies for a wealthy widow. But mysteries abound at Fru Krak's dark old mansion. The basement appears to be haunted, townspeople claim to have seen the dead Professor Krak walking the streets as a ghost, and there are stories of desperate souls who paid the professor a visit and never emerged. In fact, there is a simple explanation for all this: the basement is home to a time machine. When their cunning investigations land them in trouble, Charlotte and Fru Schleswig find themselves catapulted through time and space to modern-day London, and there their adventures truly begin.--From publisher description.
