Chief of Police Kate Burkholder investigates the brutal death of a young Amish man in An Evil Heart, the latest installment of the bestselling series by Linda Castillo.

On a crisp autumn day in Painters Mill, Chief of Police Kate Burkholder responds to a call only to discover an Amish man who has been violently killed with a crossbow, his body abandoned on a dirt road. Aden Karn was just twenty years old, well liked, and from an upstanding Amish family. Who would commit such a heinous crime against a young man whose life was just beginning?

The more Kate gets to know his devastated family and the people-both English and Amish-who loved him, the more determined she becomes to solve the case. Aden Karn was funny and hardworking and looking forward to marrying his sweet fiancé, Emily. All the while, Kate's own wedding day to Tomasetti draws near...

But as she delves into Karn's past, Kate begins to hear whispers about a dark side. What if Aden Karn wasn't the wholesome young man everyone admired? Is it possible the rumors are a cruel campaign to blame the victim? Kate pursues every lead with a vengeance, sensing an unspeakable secret no one will broach.

The case spirals out of control when a young Amish woman comes forward with a horrific story that pits Kate against a dangerous and unexpected opponent. When the awful truth is finally uncovered, Kate comes face to face with the terrible consequences of a life lived in all the dark places.
