A top security prison below the surface of the Gulf of Mexico more secure than Guantanamo Bay or Alcatraz and far from prying eyes has some disturbing secrets. The CIA are using it as an interrogation centre, the corrupt warden wants to destroy it, the FBI are conducting operations to expose them both, the White House has a spy inside and wants to close it down any way it can and an insane convict wants to scuttle it in order to escape. On top of all of that, a secret micro-document belonging to British Military Intelligence embarrassingly ends up in the hands of a Taliban terrorist incarcerated within the prison and Stratton, SBS maritime Special Forces operative, is assigned to get it back before anyone finds out. Typically, this Falconer story kicks off at a thousand miles an hour and does not slow down until beyond the end.
