Each victim is found with a card. Elegant serif type, black on cream stock. A single word.

A lesson.

FBI forensic psychologist Dr. Juliette Carter has spent her career studying how killers think - a skill she paid for in ways she's never fully told anyone. Now Boston PD is at her door with a body staged like an equation, and a message clearly meant for someone who'll understand it. 

Detective Nicholas Hale has run out of ordinary leads. What he needs is someone who can read the language the killer is speaking in - and Juliette speaks it fluently, whether she wants to or not.

But the closer she gets to understanding the pattern, the more it starts to resemble something she's seen before. Something she survived once, and buried. Because someone out there isn't just staging crime scenes.

He's teaching a class. And Juliette is starting to realize she isn't just the profiler.

She might be the point.

A psychological thriller for fans of Gone Girl, Verity, and The Silent Patient. Book One of The Symbolist Series.
