Last year I read Steadman’s debut novel, Something in the Water, which I really enjoyed, so I was looking forward to this new one published earlier in the year.

Mr Nobodystarts with a handsome man washed up on a Norfolk beach who cannot remember his name and has no ID on his person. In fact, he has no memory at all. A young neuropsychiatrist from London, Dr Emma Lewis, is drafted in to determine if he is faking it, but Dr Lewis has her own mysterious past, having been in a witness protection program for the past 14 years, and the decision to accept the job is a risky one.

The author plays her hand carefully, drip-feeding information bit by bit, so the doctor’s back story doesn’t become clear until you are two-thirds of the way through the novel, making this a proper page-turner. There are enough hints that the amnesiac may also have a dodgy past — perhaps he was an assassin or a spy or worked for the military in some capacity.

Unfortunately, this curious medical mystery goes a bit over-the-top toward the end and heads into psychological thriller territory with a wholly unbelievable denouement. Up until the 80% mark (yes, I read this on a Kindle) I really enjoyed the story, but it was let down by a ludicrous ending that tied up all the loose bits too neatly, a common fault of the genre, I guess. And at 400 pages, it was far too long…
