Following an attempt to kill Stephen Fisher, Strickland summons the team to a secret meeting. He tells them that thirty years earlier he and Fisher were part of an intelligence group investigating the IRA but their source journalist Simon Bisley was killed in a hit-and-run and the investigation ended. Now others of the group are being murdered. Bisley had linked the IRA to a career criminal Carl Dillon who, according to Gerry's informant Tinker, has just recruited two assassins and a telling document which could incriminate Dillon was stolen from Bisley's office. However Brian believes that a rogue member of the former secret service team has a vested interest in stealing the document and silencing their colleagues over it, giving Strickland the means to go after them though the team is dissatisfied with the result.
