Seán Hartnett left the British army in 2005, operating as a covert surveillance technician at JCU-NI, the top-secret counter-terrorism unit in Northern Ireland. His experiences were published in the bestselling Charlie One, the book the British Ministry of Defence tried to ban.

But this wasn’t the end of Hartnett’s career in counter espionage. After operations in South Africa, Australia and London, he arrived home to Ireland, just as the Celtic Tiger was about to implode, but not before Hartnett gets his hands dirty in the boardrooms of corporate and official Ireland… Client Confidential is a shocking exposé of the clandestine activities that foreshadowed the worst financial crash in the history of the Irish state.

Many of the country’s leading financial institutions and business figures began to see the cracks in the economy and their paranoia rattles. Hartnett was called in to protect and gather information – to carry out covert and counter surveillance for blue chip companies, semi-state bodies, national sporting associations and convicted criminals.

In Client Confidential, Seán Hartnett lifts the lid on the worst excesses of the Celtic Tiger – the heart of corporate greed, corruption and ineptitude in Ireland is revealed; the dark secrets never meant to see the light of day, are finally exposed.
