A Stranger in Corfu by Alex Preston

On the Greek island of Vidos the past lingers like salt in the air. The inhabitants - former members of MI6 - are sent here to be forgotten. Exiled.

Either too damaged or too compromised to be allowed to live freely. For years, residents make the best of their fate - old enemies reconcile, long-lost friends swim together in the warm sea and estranged lovers share a bed once more. But secrets bind tightly.

And when one of their own washes up dead, alliances fracture and a tide of suspicion begins to rise. A vivid reimagining of a real, hidden slice of the British Intelligence Service's history, A Stranger in Corfu is an exquisitely tense and masterfully spun novel about shadowy morality, unravelled secrets and the futility of trying to outrun the past.
