Author bio

Kaite Welsh is a novelist, critic, and journalist based in Edinburgh. She is the author of the Sarah Gilchrist mysteries, historical crime novels that bring together Victorian medicine, feminist history, and the rougher corners of the city she writes about. Before the novels, she also worked as Literature Officer at Creative Scotland, which fits the broader shape of her career, books, criticism, and the practical side of literary life.

She was the sort of teenager who read about 19th century medicine for fun.

History seems to have got its hooks in early. Welsh has talked about growing up around museums through an aunt who ran education and engagement programmes, and about the way that dressing up as mill workers or Brontë sisters made the past feel close rather than dusty. Her father, a nurse, later became a useful fact checker when the novels started filling up with anatomy, illness, and poison.

The real spark for Sarah Gilchrist came when Welsh was studying at the University of Edinburgh. In the old medical school she kept passing two plaques, one for Sophia Jex-Blake, who fought for women's medical education, and one for Arthur Conan Doyle. That pairing, women breaking into medicine and crime fiction in the same building, gave her the idea of a lady medical student who solves murders.

She started writing The Wages of Sin while living in London and missing Edinburgh badly. She wrote on the Tube, on lunch breaks, and at night, then moved back to Leith around the time she found an agent. The city on the page and the city outside her window started feeding each other.

That mix of feminist history and murder mystery became her lane.

In The Wages of Sin, Sarah arrives in Edinburgh in disgrace and pushes her way into medical training while investigating the death of a patient. The Unquiet Heart picks up the story a year later and folds in upper class secrets, poison, and a murder charge close to home. Readers who click with Welsh usually like the same blend, sharp social detail, real medical texture, a lot of atmosphere, and a heroine who is stubborn, funny, and hard to bully.

Welsh's fiction outside the novels is wide-ranging. Her short stories take in roller derby, Greek myth, and ghosts, in pieces such as This Is Not Your Great-Great-Great Granddaughter's Roller Derby, The Art of Stonemasonry, and City of the Dead. She also has an MA in Sexual Dissidence and Cultural Change, and that mix of history, gender, and culture shows up across both her journalism and fiction.

Alongside the books, she has written for publications including The Guardian, the Daily Telegraph, the New Statesman, The Times Literary Supplement, and Cosmopolitan. She has also worked as books editor at DIVA, appeared on BBC radio and television, and guest lectured in creative writing. Her early work was noticed too, with shortlistings for the Scottish New Writers Award, the Moniack Mhor Bridge Award, the Cheshire Prize for Fiction, and the Spectrum Award for short fiction.

These days she still lives in Edinburgh, with her wife, three cats, and what sounds like the right number of books for someone who writes about haunted cities and ambitious women. It feels like the natural home for her work.
