In Chase Your Shadow, journalist and author John Carlin tells the gripping story of Oscar Pistorius's tragic journey from sporting icon to accused murderer.

Before Valentine's Day of 2013, Pistorius was best known as an extraordinary athlete, the 'Blade Runner' who became the first amputee in history to compete in the Olympics. Everything changed after he shot his girlfriend Reeva Steenkamp dead in the early hours of 14 February. Overnight, the Olympian's status as a role model was replaced by tales of erratic behaviour and a violent dark side.

With unique access to Pistorius himself, as well as to his friends and family, Carlin paints a portrait of a complex personality, a man whose heroic rise and even more dramatic fall is one of the most remarkable sports stories ever told.
