Matthew Macfadyen is to make an unexpected re-appearance as former Grid operative Tom Quinn in the final episode of Spooks, airing this Sunday.
Macfadyen’s character was decommissioned at the end of series three after sabotaging a mission following a crisis of faith.
Prior to that, he endured the death of colleagues, the failure of several relationships and was framed as a traitor before finally clearing his name.
Now he’s back for a fleeting appearance in what promises to be a tense finale to the last ever series of the espionage drama.
Spooks fans will have to wait until Sunday to find out what’s behind Quinn’s return – but in the meantime, there’s no harm in guessing, right?
