Proof of life / R. J. Ellory.

"Stroud's best years are behind him. A former war photographer, he's seen things no one should have to see. He left the front line before his luck ran out. His best friend and mentor, Vincent Raphael, was not so fortunate and died in an explosion. His body was never recovered; his friends buried an empty box. But then Stroud gets a call from his old editor, Marcus Haig. Two months ago Raphael was photographed in Istanbul. Stroud doesn't believe it's him, but there's money on the table for Stroud to go out there and prove he's dead. But the more he looks, the harder that becomes. Stroud's journey will take him from London, to Istanbul, to Amsterdam, Paris and Berlin - on the trail of a shadow. A man who not only should be dead - but may never have existed."--Provided by publisher.
