Judith Ann (J. A.) Jance (born October 27, 1944) is an American author of mystery novels. She writes at least three series of novels, centering on retired Seattle Police Department Detective J. P. Beaumont, Arizona County Sheriff Joanna Brady, and former Los Angeles news anchor turned mystery solver Ali Reynolds. The Beaumont and Brady series intersect in the novel Partner in Crime, which is both the 16th Beaumount mystery and the 10th Brady mystery. They intersect again in Fire and Ice.
