About Diana Thomas
Born 1959. Diana Thomas is a British journalist, writer and novelist.
Diana Thomas (formerly David Thomas; born 17 January 1959), better known by the pen name Tom Cain, is an English journalist and author of a series of thriller novels about protagonist Samuel Carver.
Biography Thomas' mother was the Liberal Democrat peer Baroness Thomas of Walliswood. Her father was a British diplomat,
She spent 25 years as a journalist, working for publications such as The Daily Mail and The Mail on Sunday. In 1989, she became the youngest ever editor of Punch magazine, a role she held for three years. In 1995, her comic novel Girl was published. In this, a man enters the hospital for minor surgery but accidentally receives the sex reassignment surgery intended for another patient. Between 2007 and 2012, she wrote a well-received series of thrillers about a former Royal Marine, turned assassin, Samuel Carver.
In 2019, Thomas began writing a column in the Daily Telegraph - A New Woman - about transitioning to become a woman, Diana Thomas. Julie Bindel, the feminist activist and writer, has criticised the column, pointing out that Thomas was previously a men's rights activist. Bindel described Thomas's 1992 book Not Guilty: The Case in Defence of Men, as "a rant about how feminists have the brass neck to blame men for the terrible things they do to women, rather than themselves."
As Diana Thomas, she has written in her defence that transitioning could be considered analogous to immigration: ‘If someone born in India comes to Britain legally, passes the citizenship test and gets a UK passport, who dares say, “You’re not British”? Only a racist. Well, as far as the law goes, when I get a Gender Recognition Certificate, I’ll be a woman, just as that immigrant is British and denying that fact would be no better than racial prejudice.'
Her writing influences include Lee Child, Ian Fleming, and George Macdonald Fraser.
