Spooks

Following "Lesser of Two Evils", the bomb in Tom Quinn's house fails to detonate, but another device goes off elsewhere, killing the Secretary of State for Northern Ireland. Patrick McCann is killed by his group for collaborating with Tom. Section D are then focused on a bombing at a secret military base in Longcross, when it has emerged that wanted Serbian war criminal Miroslav Gradic has entered Britain. Gradic's group has stolen munitions from Longcross and a military convoy to attack the British. Zoe Reynolds goes undercover to befriend Radovan Petcovic, a Serbian embassy employee and Gradic's nephew. Following the uncovering of a mole, Jim North, Section D learn that Rado is communicating with Gradic via newspaper classifieds. Malcolm Wynn-Jones decodes the next target; the Cabinet Office Briefing Rooms (COBRA) meeting Harry Pearce is attending; the team prevent the attack and arrest Gradic. Ellie Simm breaks up with Tom, realising that he will always prioritise work over her.
