From the Top 10 Sunday Times bestselling author and winner of the CWA Ian Fleming Steel Dagger for Best Thriller of the Year.

Thomas Kell is a disgraced agent who longs to come in from the cold. When MI6's top spy in Turkey is killed in a mysterious plane crash, his chance arrives... for Kell is the only man Service Chief Amelia Levene can trust to investigate the accident.

In Istanbul, Kell soon discovers that there is a traitor inside Western Intelligence. Then he meets Rachel- the dead spy's daughter- and the stakes grow higher still.

From London to Greece and into Eastern Europe, Kell tracks the mole. But a betrayal close to home transforms the operation into something more personal. Soon Kell will stop at nothing to see it through.

Perfect for fans of John le Carré, Charles Cumming is 'the master of the modern spy thriller' (Mail on Sunday)
