The Cage is a ring enclosed by a steel box where participants are urged to fight to the death - an illegal sport that attracts some of the world's richest and most powerful people as its shadowy patrons. This is the true story of the star of this deadly sport. In this compelling account of his fight for survival, X tells of his twelve-year career in The Cage. Transported to fights like some medieval warlord, he was drugged by opponents against his will and almost murdered by a gang intent on preventing him taking on another fighter, because of his reputation as the most deadly opponent in the world. X breaks the sport's strict code of silence to tell, with Wensley Clarkson's help, how he started life on the mean streets, and was led into petty crime then - just months before his 16th birthday - recruited to become the star of this most deadly of sports.
