Belsey's antagonist and former mentor, Geoff Bullseye McGovern, is the psychopath. He recruited Nick to the dark side back in the day. Nick is now suspended, under heavy investigarion, and squatting in a disused copshop in Hampstead (very contemporary). An oldish lady bangs on the door, so confused she still thinks that's how to contact the forces of law and order. Her thirty-something son has gone missing. Nick has nothing better to do, so offers to help. The son seems to be obsessed with media star Amber Knight, whose upcoming wedding is the talk of the tabloids. Missing Mark Doughty seems to be a little too interested.
So Nick wanders the short distance from Mark's mum's council flat to Amber's mansion in Primrose Hill - and blunders into a crazed celebritiy cult in which dissenters are murdered. Bullseye McGovern is the SIO. Nick finds himself the chief suspect.
What really caught my eye was the way that Nick never tries to disguise who he really is. He uses his real name, sometimes tells people that he's a cop facing serious jail time, other times let them go with their first assumptions. He does much of his investiagting on his phone. It's fascinating how skillfully Harris steers us through the madness. And the ending is not only unexpected, it's sheer bloody brilliance.
So that's two series by Oliver Harris I am now obliged to pursue, the spy novels featuring Elliot Kane, and the other novels in the Belsey series. It sounds like hard work but, hey, somebody's got to do it.
