Tom Marcus’s standalone books are his two memoirs of life inside MI5. Soldier Spy (2016) was his debut, describing the reality of domestic intelligence work — the long hours of surveillance, the physical and mental toll, and the operations that kept the UK safe from terrorist attacks.
I Spy: My Life in MI5 (2019) continued the story, offering a deeper look at the experiences that eventually led to Marcus being medically discharged with PTSD. Both books became bestsellers and established Marcus as a credible voice in the intelligence memoir genre.
