David Hewson's novels have been translated into a wide range of languages, from Italian to Japanese, and his debut work, Semana Santa, set in Holy Week Spain, was filmed with Mira Sorvino. Dante's Numbers is his thirteenth published novel.

David was born in Yorkshire in 1953 and left school at the age of seventeen to work as a cub reporter on one of the smallest evening newspapers in the country in Scarborough. Eight years later he was a staff reporter on The Times in London, covering news, business and latterly working as arts correspondent. He worked on the launch of the Independent and was a weekly columnist for the Sunday Times for a decade before giving up journalism entirely in 2005 to focus on writing fiction.

Semana Santa won the WH Smith Fresh Talent award for one of the best debut novels of the year in 1996 and was later made into a movie starring Mira Sorvino and Olivier Martinez. Four standalone works followed before A Season for the Dead, the first in a series set in Italy. The seventh Roman novel featuring Nic Costa and his colleagues, Dante's Numbers, appeared in October 2008. At the end of 2006 he signed renewed contracts with Pan Macmillan in the UK and Bantam Dell in the US to extend the series to nine books, running to 2012. The titles are published in numerous languages around the world including Chinese and Japanese... and Italian.

He has featured regularly on the speaker lists of leading international book events, including the Melbourne and Ottawa writers' festivals, the Harrogate Crime Festival, Thrillerfest, Bouchercon and Left Coast Crime. He has taught at writing schools around the world and is a regular faculty member for the Book Passage Mystery Writers Conference in Corte Madera, California, where he has worked alongside writers such as Martin Cruz Smith and Michael Connelly.
