Duchess of Cornwall Close: sheltered accommodation, a mix of bungalows and flats, newly built and not quite finished. Despite the bitterly cold weather, elderly residents are moving in. Then, one snowy night, an old lady is murdered - dragged from her bed and strangled with a length of flex. DCS Simon Serrailler and his team are aware of bizarre circumstances surrounding her death, but keep some details secret while they desperately search for a match. All they know is that the killer will strike again, and will once more leave the same tell-tale signature.
Then Simon's former sergeant, the ever-cheerful Nathan Coates, tracks down a name: Alan Keyes. But Alan Keyes has no birth certificate, no address, no job, no family, no passport, and no dental records. Nothing. Alan Keyes does not exist.
The seventh in the best-selling Simon Serrailler series, A Question of Identity is Susan Hill's most thrillingly imagined crime novel to date.
