Eclipse - Nicholas Clee

His four rivals are so far behind him that, in racing terms, they are "nowhere." Watching Eclipse is the man who wants to buy him. An adventurer and rogue who has made his money through gambling, Dennis O'Kelly is also companion to the madam of a notorious London brothel.
While O'Kelly is destined to remain an outcast to the racing establishment, his horse will go on to become the undisputed, undefeated champion of his sport. Eclipse's male-line descendants include Secretariat, Barbaro, and all but three of the Kentucky Derby winners of the past fifty years.
