When Ben Johnson smashed the 100 metres world record to crush his rival Carl Lewis and win gold at the 1988 Seoul Olympics , he swore that the gold was more important than the record: while the record would be beaten one day, the medal, well, 'they can't take that away from you'.

How did Johnson get caught? Was sabotage involved? Richard Moore unravels a complex tale of espionage, corruption, and connivance that extended to sport's most powerful men and tracks down the surviving principals, including Ben Johnson and - after a lengthy quest - the enigmatic Carl Lewis.
