spring 2017. Retired Chief Inspector Patrick Mullan is found brutally murdered in his bed. Detective Sergeant Ryan McBride and his partner Detective Sergeant Billy Lamont are called to his desolate country home to investigate. In their inquiry, they discover a man whose career with the Police Service of Northern Ireland was overshadowed by violence and corruption. Is the killer someone from Mullan's past, or his present?

And who hated the man enough to kill him twice?

Ryan and Billy once again face a complex investigation with wit and intelligence, all set in Belfast and the richly atmospheric countryside around it.
