The tightrope men - Desmond Bagley

A man wakes up in an Oslo hotel room and doesn't even recognize his own face. Yet he seems to be at the centre of an international conspiracy.

He knows he is Giles Denison of Hampstead. But that is the only thing he knows for sure. He wakes up one morning in an Oslo hotel, and the face in the mirror is not his face.

But this is only the beginning of a hair-raising adventure in which Denison finds himself trapped, with no hope of escape. One false move from him and everything will be over, the whole delicately balanced power structure between East and West will come topping down.
