This plague of souls
(Book)

"After a period of imprisonment, Nealon returns to an empty house in the west of Ireland to find his wife and young son missing. Then he gets a call from a man who claims to know what's happened to them--a man who'll tell Nealon all he needs to know in return for a single meeting. In a hotel lobby, in the shadow of an unfolding terrorist attack, Nealon and the man embark on a conversation shot through with secrets and unknown dangers, a verbal game of cat and mouse that ranges from Nealon's past and crimes to Ireland's place in the world order to the location of his family."--,Provided by publisher.
