The Meridian Line: A Blood Compass Novel Where Every Pattern Has an Origin (The Blood Compass Cases Book 1)

She built her career catching killers. This case will cost her everything she believes about herself.

Detective Constance Egan is the sharpest investigator in the St. Louis Metropolitan Police Department’s Homicide unit — a woman whose uncanny ability to read crime scenes and decode human behavior has made her both indispensable and unsettling to everyone around her. When a woman’s body is found on a levee south of the Chain of Rocks Canal, arranged with disturbing precision, Constance recognizes something in the ligature pattern that she can’t explain. Something older than her badge. Something lodged in a memory she didn’t know she had.

As she traces a thread of cold cases stretching back twenty years along the I-70 corridor — women no one searched for, killed and discarded in jurisdictional blind spots by a predator who understands infrastructure the way an architect understands load-bearing walls — the investigation pulls her deeper than any case has before. Past buried police files and silenced witnesses. Past a retired detective drowning in guilt. Past the professional instincts she trusts and into a place where the evidence stops feeling like evidence and starts feeling like a memory she locked away as a child.

The closer Constance gets to the killer, the more the case begins to feel like it was always waiting for her — as though the corridor, the pattern, and the hunt itself were designed for someone with exactly her skills, exactly her history, and exactly the things she has spent her whole life refusing to remember.

The Meridian Line is a searing literary thriller set against the sweltering heat of St. Louis and the industrial sprawl of Missouri’s I-70 corridor. It is a novel about the women the system forgets, the detectives who refuse to forget them, and what happens when the hunt leads somewhere the hunter cannot survive unchanged. A story about institutional failure, inherited instinct, and the most dangerous question a detective can face: what if finding the truth means destroying the only foundation you’ve ever stood on?
