The Killing Jar

By Alex Sigmore

Some places are built to heal. Others are designed to hurt.

Special Agent Emily Slate has just been appointed to lead a new team within the FBI. It's a fresh start. A new boss. A new mandate. But no time to breathe.

A series of disturbing reports from a remote psychiatric facility land on her desk-patients suddenly cut off from family, strange staff turnover, and whispers of something far more sinister beneath the surface.

The deeper she and her team dig, the clearer it becomes: this isn't about mental health. It's about power, control, and silence. And someone inside will do whatever it takes to keep the truth buried-even if it means killing to protect it.

As the lines between sanity and conspiracy blur, Emily must navigate the shadows of an institution built on secrets... before she becomes its next patient.

The Killing Jar is a chilling new entry in the Emily Slate Mystery Thrillers by bestselling author Alex Sigmore. Perfect for returning fans and new readers alike, this standalone mystery delivers razor-sharp suspense, gripping twists, and a heroine who never backs down-even when the system is designed to break her.
