And Dead man Running.
I read the first book in a day and half way through the second.
True account of a man recruited by Special Branch to infiltrate the IRA during the height of the troubles in Northern Ireland. Gives really good background on what things were like as a Catholic living in those times, both the intimidation by the RUC and the British Army as well as the punishments doled out by the IRA for perceived wrong doings.
The second book covers his life on the mainland and how he was betrayed by the British authorities and MI5 and sold out to the IRA.
Really great read if you like true stories and looking back at the history of these times.
