The Echo Maker

On a winter night on a remote Nebraska road, twenty-seven-year-old Mark Schluter flips his truck and nearly dies. His older sister, Karin, his only close relative, returns reluctantly to their home town to nurse him. When he emerges from a long coma, Mark is convinced that the woman who looks and sounds exactly like his sister is an impostor.

Karin contacts Gerald Weber, a neurologist famous for his case histories, who recognises a rare instance of Capgras syndrome and comes to investigate. Mark, meanwhile, tries to find out what really happened on the night of the accident, with only an anonymous note to go on.
