Filled with roller coaster emotions and explosive revelations of covert operations, Charlie One provides a unique, detailed and unbiased account of the secret war fought in Northern Ireland.

Seán Hartnett grew up in Cork in the 1970s where he observed the worst of the northern Troubles. Despite his family’s republican ties and his own attempt to join the IRA, Hartnett shocked family and friends when he joined the British Armed Forces. In 2001 Hartnett returns to his native Ireland, but this time as a member of the British Army’s most secretive covert counter-terrorist unit in Northern Ireland. For the next three years Hartnett is directly involved in some of the highest profile events of that period, from the arrest of John Hannan for the bombing of the BBC in London and some of the biggest blunders by British Intelligence in the history of the Troubles.
