Ann Rae Rule (née Stackhouse) was a renowned American author of true crime books and articles. Born on October 22, 1931, in Lowell, Michigan, she became a prominent figure in the genre of true crime literature.

Ann Rule gained fame with her compelling book, The Stranger Beside Me (1980), which provides an insider's perspective on the notorious serial killer Ted Bundy. In a unique twist of fate, Bundy was not only the subject of her book but also her co-worker and one-time friend. This unusual connection gave Rule a distinctive edge among true crime writers.

Throughout her career, Ann Rule authored over 30 true crime books, many of which focused on murder cases in the Pacific Northwest and her adopted home state of Washington. Notable works include Small Sacrifices, which delves into the chilling case of Oregon child murderer Diane Downs.

Raised in an environment steeped in law enforcement and criminal justice, Rule initially aspired to work in law enforcement herself. She was a former Seattle policewoman and was well-versed in psychology and criminology. This background provided her with a unique insight into the criminal mind.

Ann Rule's contributions to the true crime genre were recognized with two Anthony Awards from Bouchercon, the mystery fans' organization.
