The Kremlin does not forget. Nine years ago, high-ranking Russian military intelligence officer Sergei Strelkov fled the country, accused of selling state secrets to MI6. Defecting to the UK, Strelkov went into hiding. The Kremlin does not forgive. Nine weeks ago, Strelkov was found slumped on a bench in Salisbury, poisoned with a lethal nerve agent - the victim of a botched assassination attempt. The Kremlin will always find you. Now Strelkov is missing, kidnapped from a remote safe house by a Russian snatch squad. With nowhere to run, Strelkov faces the ultimate choice: work with his sworn enemies, or face the wrath of the motherland.

Meanwhile, ex-Regiment heroes Porter and Bald are drafted in by MI6 for a highly-sensitive mission. Their target: Dennis Lapage, a flamboyant British populist and suspected Moscow agent. Six believes that Lapage is planning something big ahead of a secretive far-right gathering - and they want Bald and Porter to help bring him down. Going undercover as bodyguards, they must infiltrate Lapage's inner circle, win his trust and gather vital evidence. But as they get closer to the truth, Bald and Porter find themselves caught up in a terrifying conspiracy: one that threatens to bring down the established order of the West. And only Porter and Bald, two battle-hardened Blades, stand between survival and global chaos.
