Milo Weaver is still haunted by his last job. As an expert assassin for the Department of Tourism, an ultra-secret group of super-spooks buried deep in the corridors of the CIA, he fought to keep himself sane in a paranoid and amoral profession. Now, the Department has been destroyed, and with it Weaver's livelihood. Finally he can spend time with his family - without constantly looking over his shoulder and fixing one eye on the exits. Weaver's former boss is not so settled. For Alan Drummond, Tourism was everything. Now, all he wants is to take revenge on the Chinese spymaster that exploded their operations from within. Weaver tries to persuade him to leave sleeping cells lie, but when Drummond disappears from a London hotel room after a serpentine journey through the world's cities, Weaver is sucked back down into his old life. Investigating Drummond's intentions in London throws up more questions than answers. Why was an ex-Tourist in his hotel room that night? Why is homeland security suddenly asking questions? And how are the Chinese connected? Soon, Weaver is sifting through what secrets, lies and misinformation he can extract from the sources he still has on the ground. If his time as a Tourist has taught him anything, it's that nothing and no-one can be trusted - even within the CIA itself...
