Author bio

Mark de Castrique was born in Hendersonville, North Carolina, near Asheville, and his earliest address was unusual: his family lived above the funeral home run by his father. That childhood setting stayed with him. Years later, it helped spark the Buryin' Barry mysteries and gave him a natural way into crime fiction.

He grew up with the mountains of western North Carolina close at hand, and that landscape still matters in much of his work. His books often return to small towns, old local stories, and the pressure that comes when people would rather leave the past alone.

The funeral home was a beginning, not the whole story.

Before becoming a novelist, de Castrique built a long career in television and film production. He worked in Washington, D.C., directing news and public-affairs programs, and his documentary work earned an Emmy Award. That experience taught him how to shape a story for an audience, and it also gave him a working knowledge of the city that later fed into his Washington-set thrillers.

He came to fiction by what he has called a side door. Screenwriting courses gave him some early practice, then a short-story class in Charlotte introduced him to a supportive writing group. Graduate study in English let him focus on narrative structure and revision, and the creative work from that period became his route into publishing. His first mystery novel, Dangerous Undertaking, arrived in 2003.

He learned that writing is rewriting.

That debut introduced Barry Clayton, a former police officer who returns to the fictional North Carolina mountain town of Gainesboro to run the family funeral home. The Buryin' Barry books mix close-knit community life with crimes involving land, money, family history, and the awkward practical details of death. Grave Undertaking, Risky Undertaking, and Secret Undertaking keep Barry moving between his duties as an undertaker and his work as a part-time deputy.

De Castrique later shifted to Asheville for the Sam Blackman novels. In Blackman's Coffin, an injured former Army investigator is drawn into a murder linked to a century-old journal. Sam and his partner, Nakayla Robertson, go on to investigate cases where local history has a sharp edge, from literary puzzles in The Fitzgerald Ruse to environmental conflict in Fatal Scores.

His Washington stories take a different route. The 13th Target follows a former Secret Service agent caught in a threat against the financial system, while The Singularity Race turns toward artificial intelligence and international competition. The Secret Lives mysteries put retired FBI agent Ethel Fiona Crestwater, a very capable woman in her seventies, at the center of political danger, espionage, and family loyalty.

Across these books, de Castrique tends to pair present-day danger with unfinished business from years before. He also writes middle-grade mysteries, short fiction, and the stage play A Dying Business. He and his wife, Linda, live in Virginia near their two daughters and grandchildren.
