MI5 officer Liz Carlyle is posted to Northern Ireland. From the moment she lands in Belfast, danger follows. She soon discovers that the peace process in the province is precarious.

Then a source reports strange goings-on at a house on the Irish Sea owned by the Fraternity, an organisation Liz suspects of being a front for renegade former IRA men. Its head is Seamus Piggott, an Irish-American with a gun-running past. When another informant reports a plot is being hatched against the security forces, Liz and her colleague Dave Armstrong suspect Piggott is involved, along with a former French Intelligence officer.

Moving from London to Belfast to the South of France, the latest Stella Rimington Liz Carlyle novel is a propulsive thriller filled with action and nail-biting suspense.
