Rodney David Wingfield was born in Hackney, east London in 1928. He was educated at the Coopers' Company School and during the Second World War was evacuated to Frome, Somerset. Wingfield was exempted from National Service due to poor eyesight and had various office jobs in the East End before joining the Petrofina oil company. His first radio play, Compensating Error was accepted by the BBC in 1968 and two more were then commissioned, at which point Wingfield resigned from his job. His radio plays are discussed at ukonline

In 1972, Macmillan Publishers invited him to write a book, and he wrote Frost at Christmas. This was rejected and not published until the early 1980s in Canada. Wingfield had originally planned to kill Frost in the first book, but he was persuaded instead to leave it as an open ending. Following this, two more Frost books were written: A Touch of Frost and Night Frost. In 1977 Frost appeared in a radio play called Three Days of Frost, in which Frost was played by Leslie Sands, a friend of Wingfield's. The books were first published in the United Kingdom in the early 1989, and in 1992 Frost first appeared on television in A Touch of Frost, played by David Jason. Wingfield was never enthusiastic about the TV adaptation of his detective, once saying he had nothing against David Jason but "he just isn't my Frost".

Hard Frost was published in 1995, followed by Winter Frost in 1999. Wingfield did not enjoy writing books, and much preferred writing radio scripts. In 20 years he wrote over 40 radio mystery plays, but stopped in 1988, with Hate Mail, due to the decline of radio and the success of his Frost books. As well as the many mystery plays, Wingfield also penned a comedy radio series, The Secret Life of Kenneth Williams, starring Kenneth Williams as a secret agent. Wingfield was a very private man, always avoiding book launches and publishing parties, and being rarely photographed.

In 2002, R. D. Wingfield was diagnosed with prostate cancer. At about the same time he started writing the sixth, and final, Frost book, A Killing Frost. His wife, Phyllis Patten, whom he married in 1952, died in 2004. They had a son, Phillip. The cancer killed Wingfield in 2007, and his final book, A Killing Frost, was published on 7 April 2008.
