I Spy My Life in MI5

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 out smart 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.
