Mr Nobody / Catherine Steadman.

Includes excerpt from Some thin in the water.

"When a man is found on a Norfolk beach, drifting in and out of consciousness, with no identification and unable to speak, interest in him is sparked immediately. From the hospital staff who find themselves inexplicably drawn to him; to international medical experts who are baffled by him; to the national press who call him Mr Nobody; everyone wants answers. Who is this man? And what happened to him? Neuro-psychiatrist Dr Emma Lewis is asked to assess the patient. This is her field of expertise, this is the chance she's been waiting for and this case could make her name known across the world. But therein lies the danger. Emma left this same small town in Norfolk fourteen years ago and has taken great pains to cover all traces of her past since then. But now something - or someone - is calling her back. And the more time she spends with her patient, the more alarmed she becomes. Has she walked into danger?"--Publisher description.
