25 years ago, Mark Billingham’s debut novel Sleepyhead became an instant bestseller, launching a prolific career as a novelist.

Born in Birmingham, he worked as an actor and stand-up comedian before becoming a full-time author, best known for playing the role of Gary in the cult children’s TV show, Maid Marian and Her Merry Men. Mark continues to be a regular face and voice on TV and radio.

Sleepyhead introduced Detective Inspector Tom Thorne, leading to a further 18 books in the series, which was adapted to screen by Sky 1 in 2010, starring David Morrissey as Thorne. The latest Thorne book, What the Night Brings, was published in June 2025 – Billingham’s 25th book.

Mark Billingham said: “Presuming this is not an administrative error, I could not be more thrilled or honoured. To be added to a list that features most of my literary heroes is fantastic. That so many are also friends is the icing on the cake and, for me, a mark of how very special the crime-writing community is.”

In 2023, Billingham introduced a new series featuring DS Declan Miller with The Last Dance followed by The Wrong Hands (2024). The third book in the series, The Shadow Step, is due out this year. His stand-alone novels include In the Dark, Die of Shame and Rabbit Hole. A series based on the novels In the Dark and Time of Death was screened on BBC1 in 2017.

Nadine Matheson, Chair of the CWA, said: “Across a remarkable body of work, Mark has consistently set the bar for contemporary crime fiction, while also being generous with his time and support to emerging writers. His influence on the genre extends far beyond his own novels, shaping the crime writing community as a whole. For his outstanding contribution to crime fiction, his lasting impact on readers and writers alike, and his commitment to the genre, Mark Billingham is a thoroughly deserving recipient of the Diamond Dagger.”

In 2022, Billingham won the CWA’s Dagger in the Library, voted by librarians, for his body of work. He’s also been awarded the Theakston Old Peculier Crime Novel of the Year twice (Lazybones, 2005 and Death Message, 2009).

Sponsor of the CWA Diamond Dagger, Karen Baugh Menuhin, said: “As sponsor of the CWA Diamond Dagger, I am thrilled to congratulate Mark Billingham on being chosen as the 2026 recipient of crime fiction’s highest honour. His place amongst crime writing royalty is hard won and richly deserved.”

Mark is also a member of the rock band, The Fun Lovin’ Crime Writers, a combo of bestselling crime and thriller writers (Val McDermid, Luca Veste, Doug Johnstone, Stuart Neville, and Chris Brookmyre) who performed at Glastonbury in 2019 and 2024.
