Joanne Kilbourn is a fictional Canadian detective, who appears in mystery novels by Gail Bowen.
In Deadly Appearances, the first Kilbourn novel, she is a political strategist and advisor to Andy Boychuk, a politician who is murdered just hours after being elected Leader of the Opposition in the Legislative Assembly of Saskatchewan.
In the course of the later novels, she solves crimes committed both within the academic community and throughout the province of Saskatchewan.
Kilbourn is also a widow, whose husband was himself murdered several years before the events of Deadly Appearances.
In A Colder Kind of Death, she is forced to investigate the killing of her late husband's murderer.
