A Most Wanted Man | Ле Карре Джон; Penguin, 2018

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.
