10 Most Shocking Moments In Spooks
6. Tom Quinn's Apparent Suicide
Matthew Mafadyen's Tom Quinn was the original face of the show. Tom faced many personal and professional struggles before having an attack of conscience and being rather coldly decommissioned by Harry Pearce early in Series 3.
One of his most challenging experiences was when vengeful CIA agent, Herman Joyce (Tomas Arana) framed him for the assassination of the Chief of the Defence Staff. Fleeing from his allies in an effort to prove his innocence, Tom shot Harry Pearce in the shoulder with a shotgun before supposedly drowning in the North Sea. His friends and colleagues, Danny Hunter and Zoe Reynolds could only stand by, fearing the worst, whilst search and rescue teams combed the area.
It was a shocking conclusion to Series 2, proving that the show did not need to set off explosions to keep the audience's attention.
Even though Tom experienced a "conscience explosion" shortly after his return in Series 3, he was never far from viewers' hearts, ultimately proving so popular that he returned for a cameo appearance in Series 10.
