In his talks to communities throughout the length and breath of Ireland, John Lonergan finds himself coming back to one theme: the importance of kindness. It is an unexpected theme for the former boss of Ireland's biggest and toughest prison, Mountjoy, but then John Lonergan is an unusual man.

John entered the prison service in 1968 and in the years that followed, as he saw human nature at its worst - and often, unexpectedly, at its best - he developed a deep understanding both of human nature and of Irish society.

Now, after 42 years in the service, 26 of them as the most senior prison officer in the country, John tells his fascinating life story - from his idyllic childhood in rural Tipperary, to coming face to face with the ugliest face of Irish life, to grappling with the politics of working in a service that was the plaything of officials and politicians. His description of life in the prison service is not only a gripping account of humanity at its rawest, but also an invaluable primer for anyone in top level management.

Revealing, surprising and inspiring The Governor gives a unique insight into modern Ireland.
