I Spy: My Life in MI5

'Intense and eye-opening' Jeremy Irvine


Tom Marcus spent years in MI5 working covertly to stop those who want to do us harm. In I Spy he takes us deep undercover as he puts his life on the line during top-secret operations across the UK.


Plunging the reader straight into the action, Tom and his team stake out a terrorist training camp in the Welsh mountains, race to prevent a horrifying attack on a school, and outsmart Russian agents, blocking a daring plot that threatens the security of the nation. Relying on their quick wits, training and courage, the extraordinary men and women of MI5 are put under intense pressure. Not everyone is suited for the work, and Tom shows how the incredibly tough challenges he faced growing up gave him the mental strength and skills to survive in a dangerous world.


Gritty and eye-opening, this is a unique insight into a hidden war and the sacrifices made by those who fight it. You will never take your safety for granted again.
