Authors of 'LA Confidentiel' to release new book on Armstrong

French authors Pierre Ballester and David Walsh, co-authors of the controversial book LA Confidentiel, are set to release a follow-up to that book on Thursday, called LA Official: the anatomy of a scandal. In this book, the two renew their accusations that Lance Armstrong used performance enhancing drugs to win the Tour de France seven times.

"Beyond the web of deception that Lance Armstrong spun around his image," reads a statement from the authors, "one has to ask questions about the serious repercussions of this tactic. After the disturbing revelation of a blood-doping network in Spain and the shameful Floyd Landis episode, does elite cycling retain any crumbs of credibility?"
