Ross Pennie was born in Quebec City, and by the time he was a boy taking notes on a solo train trip, he was living near Medicine Hat, Alberta. At ten, he crossed the Prairies and Rockies by rail and wrote about what he saw. That habit of noticing small details, and wanting to get them right, stayed with him.

Long before he published fiction, Pennie built a career in medicine. He worked in Papua New Guinea as a young doctor, later practiced as an intensive-care pediatrician and infectious-diseases specialist, and eventually taught at McMaster University while also working at Brantford General Hospital in Ontario. His patients included children, truckers, hockey players, outspoken nuns, and people facing infections that could turn serious very fast.

Medicine came first, but writing had been waiting in the wings for years.

A major turning point came in his mid-twenties, when he took a two-year volunteer posting at Vunapope Mission on the island of New Britain in Papua New Guinea. He arrived with a fresh medical degree and a lot of nerve. He left with hard-earned experience, a humbler view of the job, and the material that became Unforgiving Tides, his memoir about improvising medicine far from the comforts of a modern hospital.

That memoir shows a lot of what readers later found in his thrillers. There is humor, even in rough situations. There is also a doctor's-eye view of what fear, exhaustion, and uncertainty do to people, both patients and the people trying to help them.

After early retirement from medicine, Pennie turned more fully to fiction and introduced Dr. Zol Szabo in Tainted. The novel follows a public-health doctor racing to trace what looks like mad cow disease before panic outruns the facts. He built on that with Tampered, about fatal food poisonings in a seniors' residence, and Up in Smoke, where teens die of liver failure and the trail leads into Ontario's illegal tobacco trade.

The later books widen the canvas. Beneath the Wake traps Zol on a luxury cruise ship with a deadly infection moving through the crew, while Bitter Paradise pairs a Hamilton polio outbreak with the story of a Syrian refugee surgeon trying to rebuild his life as a barber. Readers who click with Pennie's books usually like the same mix, real medical detail, steady suspense, local texture, and characters who feel like working people rather than action figures.

He knows how quickly a quiet problem can become a public crisis.

Pennie's fiction returns again and again to contamination, bureaucracy, bad decisions, and the strain that pressure puts on families and colleagues. But it also keeps sight of decency, competence, and the odd bits of humor that help people get through ugly days. His first two Zol Szabo novels, Tainted and Tampered, won Arts Hamilton Literary Awards for adult fiction.

These days he lives in southern Ontario with his wife, Lorna, and he is the father of two grown children. After four decades in medicine, he writes the kind of medical mystery that feels lived in because, in many ways, it is.
