Slough House has been deleted from the Regent Park mainframe. The Slow Horses are being tailed. Ex-Slow Horses are being tracked down and killed. Jackson Lamb, for all his innumerable faults, is not going to tolerate things happening to his joes - which is bad news for those who commit such affronts.
Diana Taverner, first desk at the Park, has meanwhile dabbled with privatisation. Not for personal gain, of course, but because the GRU have been sending over idiots to spread toxic chemicals around English cities. This turns out to be a mistake on many levels, not least of which is that, in her hour of need, she has to turn to Jackson Lamb.
Also back in the frame is Sid (Sidonie) Baker, who once took a bullet for River Cartwright, is back from the dead, hiding out at the country house River just inherited from the Old Bastard. She thinks she is being pursued by Mormon missionaries. The Yellow Vests are venting on the streets of London and Jackson Lamb meets a gay American of restricted growth who believes his boyfriend has been murdered on the orders of Vladimir Putin.
Mick Herron's alternative take on the Secret Service is back for a seventh anarchic romp - the best to date in my opinion. The critical take on contemporary Britain is absolutely on the nose and there were many laugh out loud moments. Herron is also excellent on the suspense, where needed, and the car chase through benighted rural Kent was beautifully done. A masterpiece of its kind.
