This chapter provides a brief biographical background of the True Crime writer, Ann Rule. Rule’s early childhood through to adulthood are outlined here, highlighting long-standing ties to law enforcement—owing to the professional roles of various family members—before she entered this field herself. Rule’s untimely exit from law enforcement, owing to a minor health complaint, resulted in her exploring writing professionally instead. She began writing for True Detective magazine before moving into long-form True Crime narratives. Rule’s (The Stranger Beside Me. Sphere, 1989) first book, The Stranger Beside Me, is referenced here as a springboard publication into a longer writing career that would span decades. The intricacies of this narrative, that saw Rule develop a personal acquaintance with Ted Bundy, are also highlighted. Rule would go on to write over thirty New York Times bestsellers, penned in what would become her trademark blend of reportorial and autobiographical narratives. The final months of Rule’s life—following a fall at her home, and resultant health complications that led to her hospitalisation—are also documented.
