I Spy

Tom Marcus, former MI5, grew up on the streets in the north of England. He joined the army at sixteen and went on to become the youngest member of the Armed Forces to pass the six-month selection process for Special Operations in Northern Ireland.

He was hand-picked from the army into MI5 as a Surveillance Officer. He left the Security Service recently after a decade on the frontline protecting his country due to being diagnosed with PTSD.

An extraordinary battle and recovery took place, which led Tom to write his first book, Soldier Spy, which has been vetted and cleared for publication by MI5; it was the first true ground-level account ever to be told, and the first time in the Security Services' history that a Surveillance Officer has told the real story of the fight on our streets. Soldier Spy went straight to number one on the Sunday Times bestseller list.

Tom now consults on TV and film projects, including the TV dramatization of his book Soldier Spy.

Due to the ongoing specific threat to Tom Marcus, MI5 insist he keep his identity hidden and he continues to work with the Security Services and other agencies to ensure he stays safe.
