'A gripping tour de force – reveals the inside story of the secret war in Northern Ireland, from one who was there, at the very heart of the darkness. A riveting, insightful, rollercoaster read. Truly revelatory.' – Damien Lewis, Sunday Times No. 1 Bestselling Author

SOUTH ARMAGH, NORTHERN IRELAND, 1983. Will Britten, 23, has just qualified as an agent handler for the British Army's ultra-secret Force Research Unit. He and a fellow agent handler complete the detailed paperwork following a covert meet with one of the Detachment's most important agents, who has successfully infiltrated 'Mad Dog' McGlinchey's INLA Active Service Unit.

A few days later, there is a phone call. The draft Contact Form wasn't put in the burn bag. Both PIRA and INLA now know his real name.

The Deadly Game is the memoir of a military intelligence officer with the FRU – a unit so secret that the rest of the army barely knew it existed. Their role was to infiltrate terrorist cells on both sides of the Troubles, to gather intelligence and disrupt them from the inside. Will Britten provides a unique insight into one of the most successful intelligence units of all time, and the part they played in ultimately bringing Republican terror to the negotiating table.
