John le Carre 
A Most Wanted Man 

»One of the most sophisticated fictional responses to the war on terror yet published» Guardian
An illegal Muslim immigrant arrives in Hamburg with a traumatic past and the key to a fortune held in a private bank. He says his name is Issa. To the idealistic young human rights lawyer Annabel, determined to save him from deportation, he is a worthy cause. To the intelligence services of Britain, Germany and America, however, he is a potential jihadist – and a pawn between them as they seek to make a kill in the war on terror.
A Most Wanted Man is a gripping and disquieting story of paranoia, disillusionment and betrayal in the moral no-man»s land of the post-9/11 world.
