El Infierno: Drugs, Gangs, Riots and Murder: My Time Inside Ecuador's Toughest Prisons, Paperback

"Gato's head snapped back... We could make out the shots of several 9mms, a couple of 38s and one or two 45s. I hurled myself through the doorway and into the room. I didn't look back."

Caught in an Ecuador hotel room with 8kg of cocaine, Pieter Tritton was no mule or dupe. He had planned and organised everything. The consequence: a 12-year sentence inside one of the world's deadliest prison systems, where gun fights, executions and riots are a part of everyday life. As a Brit banged up abroad, Pieter had to learn how to survive - and fast - because one wrong move would mean death.

This is the insider account of what it's like to live in a place worse than hell and come out a changed man on the other side.

Pieter Tritton walked out of Wandsworth Prison on 26 August 2015, after serving the last two years of his sentence there. He has returned to his home town and with the help of a loving family and friends is building a new life.
