Day 115. Saturday 10th November 2001. 6.38am.

It's all an act. I am hopelessly unhappy, dejected and broken. I smile when I am at my lowest, I laugh when I see no humour, I help others when I need help myself. I am alone.

The final volume of Jeffrey Archer's prison diaries, A Prison Diary Volume III: Heaven, covers the period of his transfer from Wayland to his eventual release on parole in July 2003. It includes a shocking account of the traumatic time he spent in the notorious Lincoln jail and the events that led to his incarceration there – it also throws light on a system that is close to breaking point.

Told with humour, compassion and honesty, it closes with a thought-provoking manifesto that should be applauded by the Establishment and prison population alike.
