Overview

A body in the water. A missing organ. A ritual too precise to be random.

Franke & Stein: The River Saint launches a gripping new series by JA Armstrong, introducing a disturbing pattern of cold cases—women found posed by rivers and waterfalls, marked by surgical precision and haunting symbolism. For FBI Agent Rebecca Stein, a recent case strikes an unnerving chord. For Detective Amelia Franke, it holds echoes of a murder that has haunted her for years.

A trail of victims that spans decades, each bearing the hallmarks of a killer who treats murder as a form of art: a structured, terrifying “arrangement." Solving decades-old cases requires more than piecing together clues; it demands a foundation of trust.

As they dive deeper into the past, they begin to lean on each other in unexpected ways. Together, they must navigate not only the complexities of old cases but also the slow, cautious unfolding of a partnership that could evolve into something more. With Frankie’s daughter, Rory, and the mothers who raised them both at their backs, these cold cases stir old grief while also creating space for healing, hope, and a new kind of family.

The River Saint blends psychological suspense with emotional resonance, pairing the darkness of a chilling mystery with the quiet strength of two women building something extraordinary—one truth at a time.
