Author bio
David Williams was born in Bridgend, Wales, on June 8, 1926, and grew up in a household where words clearly mattered. His father was a journalist, and Williams would go on to build a life around language too, first in advertising and later in crime fiction. He was educated at Hereford Cathedral School and then at St John's College, Oxford, where he read Modern History after wartime service in the Royal Navy.
For a time, writing was not the obvious destination.
After Oxford, Williams seriously considered the Anglican priesthood, but his working life began in advertising instead. He started as a medical copywriter, moved quickly through the business, and in 1958 founded his own agency. Over the next two decades he became a major figure in British advertising, running a successful firm and appearing on radio and television as a thoughtful defender of the trade.
He had been writing fiction on the side, and Unholy Writ appeared in 1976. Then, in 1978, he suffered a severe stroke. He recovered enough to keep going, but he knew he could not return to the strain of agency life, so he made crime writing his full-time work. What could have ended one career became the start of another.
That second act was a busy one. Williams wrote twenty-three crime novels in all. Seventeen featured Mark Treasure, a calm, well-connected merchant banker who keeps getting pulled into murder cases involving old houses, art, money, churches, advertising, and business rivalries. Readers who enjoy Unholy Writ, Advertise for Treasure, Murder in Advent, and Treasure in Oxford usually like the same things in all of them, careful plotting, dry humor, and a sharp understanding of what respectable people do when reputation and cash are on the line.
His other main series began with Last Seen Breathing in 1994 and followed Detective Chief Inspector Merlin Parry and Sergeant Gomer Lloyd in Cardiff and South Wales. These books are closer to police procedure, but they keep Williams's taste for well-laid clues and sly observation. Death of a Prodigal, A Terminal Case, and Practise to Deceive all show how good he was at turning gossip, blackmail, family tension, and quiet social bitterness into proper detective stories.
Faith mattered to him, too.
Williams stayed strongly attached to the Anglican Church throughout his life. He served as a churchwarden of St Mary Aldermary and as a governor of Pusey House, Oxford. That part of his life runs straight through the fiction. Books like Murder in Advent, Holy Treasure!, and Treasure by Post feel convincing because he understood church politics, old buildings, committees, and the mix of devotion, pride, and human folly that gathers around institutions people claim to revere.
He also earned the respect of other crime writers without ever sounding grand about it. Two of his novels were shortlisted for the Crime Writers' Association Gold Dagger, and in 1988 he was elected to the Detection Club. He died in Virginia Water, Surrey, on September 26, 2003, leaving his wife Brenda and their two children. What lasts is the particular tone he brought to crime fiction, witty, orderly, humane, and just mischievous enough to keep every polished surface looking suspect.
