How Karen Vail Began
Alan Jacobson, a former chiropractor turned novelist, crafted Karen Vail in the mid-1990s after a chance meeting with FBI agent Mark Safarik. This encounter sparked over a decade of research with the FBI’s Behavioral Analysis Unit, giving Jacobson unparalleled insight into criminal profiling. Inspired by real-life profilers and his own New York upbringing, Jacobson envisioned Vail as a trailblazing female profiler—smart, tenacious, and unafraid to break the mold. Initially a one-off character, Vail’s electrifying debut in The 7th Victim (2008) won over readers and critics, prompting Jacobson to transform her into a series star.
The Heart of Karen Vail
The Karen Vail series kicks off with The 7th Victim, where Vail faces the gruesome Dead Eyes Killer in Virginia. The case takes a personal turn when the seventh victim unlocks secrets that threaten her career and sanity. In Crush, Vail heads to Napa Valley, hunting a serial killer who crushes victims’ windpipes, only to find the case spiraling into chaos. Velocity, its high-octane sequel, follows Vail’s desperate search for her missing boyfriend amid a web of deception. Spectrum takes readers back to Vail’s rookie days as an NYPD cop, tracing a decades-long chase for a serial killer terrorizing New York City.
Jacobson’s novels weave themes of resilience, psychological depth, and the cost of justice. Vail’s profiling expertise shines as she decodes killers’ motives, but her personal struggles—abusive ex-husband, raising a son, and navigating a male-dominated field—add raw humanity. Set against vivid backdrops like San Francisco’s Alcatraz or Hawaii’s sunny shores, the series blends meticulous research with cinematic pacing, earning praise for its authenticity and relentless suspense.
