When economist Vicky Pryce admitted taking speeding points meant for her former husband, the ex-Cabinet minister Chris Huhne, she found herself convicted of perverting the course of justice.After a very public trial she was sent to East Sutton Park prison near Maidstone. There, she kept a diary in which she recorded her very challenging experiences and her strong views on how the prison system works, especially with regard to how it treats women. The result, Prisonomics, will provide a compelling analysis of the cost to the economy, as well as the human cost, of keeping women in prison. In it, she uses her personal experiences and professional understanding to look at how prison works, and should work, from an economist's perspective. Royalties are being donated to Working Chance. Working Chance is a charity (1131802) which changes lives and changes society by finding women ex-offenders work.
