"Nixon's trademark flawless police procedural." M.W. Craven, CWA Gold Dagger winner and Sunday Times bestselling author of the Washington Poe series

... deeply emotional, a dark rollercoaster ride." Ed James

A robbery gone wrong. Seething local tensions. A troubled detective.

It’s 3am on a wet, dreary morning in the south of England. Detective Inspector Solomon Gray raids an ordinary-looking house, but inside he finds the exception: an illegal cannabis farm run by a sixteen-year-old held against his will.

Within minutes Gray rushes to another nearby incident. A homeowner has stabbed and seriously wounded a burglar. Semi-retired Charles Sowerby, claims self-defence against the intruder – a traveller by the name of Aidan Jupp, a man with a violent history of targeting society’s most vulnerable. The stabbing heightens local tensions, inflamed by far-right anti-immigrant activists and the Press. Jupp's family swear revenge on Sowerby. Then Gray discovers Jupp wasn’t acting alone, so who’s his partner?

Somehow the cannabis farm and the stabbing are connected. Can Gray figure everything out before local tensions boil over?

Set in the once-grand town of Margate, the now-broken and depressed seaside resort becomes its own character in this dark detective thriller, perfect for fans of Ian Rankin, Stuart MacBride, and Peter James. Betray Them All is the seventh book in this best-selling series featuring Detective Inspector Solomon Gray.
