Dead ringer - John Francome

When twelve-year-old David Tredington vanished, his father, one of England's top breeders, vowed never to give up the search for his son. Now, fifteen years later, David has been found alive and well in County Mayo.

When the charismatic young man returns to the family's Devonshire estate, he receives a mixed welcome. His elder sister, Lucy, distrusts him from the start. Jason, David's brother-in-law and David's cousin, George, are even less pleased to see another heir to the Tredington fortune. But David's natural skills as a jockey soon attract favourable attention in the steeple-chasing world.

Then a terrifying accident leads to an innocent stable lad's death, and David suspects that his own life is in danger. Someone knows the truth about his past and wants him to disappear all over again. David must find out who and why before it's too late
