One entry on the list:
Dead Cert by Dick FrancisRead about another entry on the list.
Most Francis yarns feature horse racing, of course. The ex-jockey's first novel was this sardonically entitled thriller, with a jockey-hero who realises that a horse against which he was racing (at Maidenhead) is put at a disadvantage when the champion jockey who is riding it is murdered before the winning post. He must turn detective.
Dick Francis's Longshot is one of Mary King's five notable books on the equestrian life.
