Dick Francis was born in South Wales in 1920. He was a young rider of distinction winning awards and trophies at horse shows throughout the United Kingdom. At the outbreak of World War II he joined the Royal Air Force as a pilot, flying fighter and bomber aircraft including the Spitfire and Lancaster. He became one of the most successful postwar steeplechase jockeys, winning more than 350 races and riding for Her Majesty Queen Elizabeth, the Queen Mother. After his retirement from the saddle in 1957, he published an autobiography, The Sport of Queens, before going on to write more than forty acclaimed books. A three-time Edgar Award winner, he also received the prestigious Crime Writers' Association's Cartier Diamond Dagger, was named Grand Master by the Mystery Writers of America, and was awarded a CBE in the Queen's Birthday Honours List in 2000. He died in February 2010, at age eighty-nine, and remains among the greatest thriller writers of all time.

Felix Francis is the younger of Dick Francis's two sons. During the last forty years Felix assisted with the research of many of the Dick Francis novels, not least Twice Shy, Shattered, and Under Orders. Since 2006, Felix has taken a more significant role in the writing, first with Dead Heat and then increasingly with the bestsellers Silks, Even Money, and Crossfire, all father-son collaborations. He continued his father's legacy with Dick Francis's Gamble and Dick Francis's Bloodline. He lives in England.
