I finished the 7th of the slow horses series earlier this week, the praise heaped on this modern take on spy novel is well deserved. Jackson Lamb is a brilliant creation, and his devotion to his 'joes', a group of rejects from mi5, is contrasted with his appalling abuse of them in all his grossness. Here, the assassination of a Russian spy after the Salisbury novichok killings leads to direct risk to Slough House. Still not seen the TV show.
