The Caitlin Dare FBI Suspense Series in Order

About the Caitlin Dare FBI Suspense series

Series Premise

FBI BAU Special Agent Caitlin Dare is a brilliant but tortured profiler haunted by a dark past that includes a deep fear of trains (stemming from childhood trauma or a related event). Despite her aversion, she is repeatedly assigned to cases involving a serial killer who stages victims on trains in highly ritualistic, symbolic ways across the country. Caitlin must confront her personal demons, work with rail police, and race against time to stop the killer before more bodies appear. The cases escalate in complexity, with the killer leaving clues tied to movement, planning, or psychological patterns. The series follows her investigations while she grapples with her history and determination to never ride a train again.

Main Characters

> Caitlin Dare — Protagonist; FBI BAU Special Agent. Brilliant profiler, rule-breaker, and haunted by her dark past. Determined, skilled, and emotionally scarred; her fear of trains is central to her character arc.
> Her partner (varies by book) — FBI or rail police colleague who assists in investigations; provides professional support and contrast to Caitlin's intensity.
> The serial killer — Changes or evolves per book; highly intelligent, ritualistic murderer who stages victims on trains; leaves symbolic clues.

> Trains, train stations, freight lines, and railway tracks across the country.
