New York Times best-selling author Linda Castillo is known as a “master of the genre” (People) for her pulse-pounding mystery series set in Amish country. Now, together for the first time in print, A Simple Murder features six original short stories starring whip-smart chief of police, Kate Burkholder.

As a violent thunderstorm rages in Painters Mill, Kate Burkholder receives a call from a frantic young Amish woman: Her two-year-old son is missing. Kate and her officers brave the downpour to search for the toddler, fearing he may have been swept away in the rising creek waters. But an explosive family secret leads Kate to believe this disappearance may be more complicated than anyone is letting on. Can she find the boy and uncover the truth before darkness falls? 

Thirty-year-old Barbara Weaver was content to live as the Amish have for centuries - without modern convenience - but her husband, Eli, wanted a life beyond horses and buggies. Soon he gave in to the temptation of technology and found ways to go Online and meet women. When Barbara was found dead, shot in the chest at close range, all eyes were on Eli... and his mistress, a conservative Mennonite named Barb Raber. Barb drove Eli to appointments in her car. She gave him everything he asked for: a laptop, rides to his favorite fishing and hunting spots, and sex.

Cases of random violence have erupted across the country - murderous acts committed by previously non-violent people. Detective Adam Boedecker, grieving brother to one of the suicide-murderers, has discovered that all the suspects had taken a new breakthrough anti-depressant, Valazine. Elizabeth Barnes has devoted her heart and soul to pharmaceutical research. She's at the top of her game and slated to be awarded top honors for her latest breakthrough drug. Until a detective contacts her about a recent wave of homicides.

Archer suspects that Eleanor knows more than she’s saying.

SFPD Sergeant Lindsay Boxer has guns on her mind. There’s buzz of a last-ditch shipment of drugs and weapons crossing the Mexican border ahead of new restrictive gun laws. Before Lindsay can act, her top informant tips her to a case that hits disturbingly close to home. Former cops. Professional hits. All with the same warning scrawled on their bodies: You talk, you die. Now it’s Lindsay’s turn to choose.

The woman’s body was found in the early morning, on a bench in a New York City playground. She was clean, her hair neatly arranged, her makeup carefully applied. But other things were very wrong - like the tattoo and piercings, clearly new. The clothes, decades out of date. The fatal wound hidden beneath a ribbon around her neck. And the note: Bad Mommy, written in crayon as if by a child.

Detective Olivia Mast would rather run through gunfire than return to her former Amish community in Unity, Maine, where she killed her abusive husband in self-defense and witnessed her family's murder. After an Amish man is murdered, the community will not answer questions from the police, so she begrudgingly dons her old prayer kapp and heads to Unity to investigate the murder undercover. To make things even worse, her captain also orders her to protect the man she dated as a teen: Isaac Troyer, who was attacked on the night of the murder but can't remember the incident.

After their last deployment, when she got shot, her fiancé, Martinez, got killed, and his bomb-sniffing dog, Elvis, got depressed, soldier Mercy Carr and Elvis were both sent home, her late lover’s last words ringing in her ears: “Take care of my partner.” On the Fourth of July weekend, when all of Northshire celebrates with fun and frolic and fireworks, the dog alerts to explosives and they find a squalling baby abandoned near a shallow grave filled with what appear to be human bones.
