Dick Francis was one of the most successful post-war National Hunt jockeys. The winner of over 350 races, he was champion jockey in 1953/1954 and rode for HM Queen Elizabeth, the Queen Mother, most famously on Devon Loch in the 1956 Grand National. On his retirement from the saddle, he published his autobiography, The Sport of Queens, before going on to write forty-three bestselling novels, a volume of short stories (Field of 13), and the biography of Lester Piggott. Dick Francis died in February, 2010, at the age of 89, but he remains one of the greatest thriller writers of all time. Felix Francis is the younger of Dick's two sons. Over the last forty years Felix has assisted with the research of many of the Dick Francis novels, not least Twice Shy, Shattered and Under Orders. But since 2006, Felix has taken a more significant role in the writing, first with Dead Heat and then increasingly with the bestsellers, Silks and Even Money. Crossfire is the fourth novel of this father-and-son collaboration.
