Intelligence is knowing whom to trust.

Someone in Trafalgar Square urgently needs your help. MI6 is also watching. You can't see either of them. SpyTrail has already begun — and you're already in it.

Through the backstreets, alleyways and hidden corners of Westminster, this is a mission that twists, doubles back and absolutely refuses to show its hand. The city looks completely normal. It really isn't. Westminster has always been where power hides in plain sight — the gentlemen's clubs, the anonymous government buildings, the park benches where dead drops were made. The story is fiction. The streets are real. And the city's actual intelligence history, which is considerably stranger than most spy novels, is woven through every stage.

Tense, funny, brilliantly plotted — this is the walk you'd never describe to a stranger on the tube. Which is entirely the point.

What you'll discover

  • A network of Government tunnels hidden beneath your feet.
  • Covert signals, encrypted clues, shady backchannels and elaborate misdirection.
  • London's espionage history etched into buildings you've passed a hundred times.
  • An off-book undercover mission through the political heart of London.
  • A chance to unmask a double agent and serve the national interest, depending on your definition of it.
