BLOODLINE, by Felix Francis

A great racing-world story in the Dick Francis style, by the master’s son and undisputed heir. When racing presenter (we’d call him announcer) Mark Shillingford discovers his twin sister Clare is fixing races, she tells him to butt out. Hours later she dies, an apparent suicide. Mark is driven into Clare’s world as he investigates. The climax is chilling, will keep you glued in your chair. Classic Francis! A 4.
