Next to the lake’s dappled water, a woman lies on her yoga mat, her limbs twisted as if she is trying to crawl away. Her mug of tea steams into the cool air, and her lips, still warm, are parted mid-sentence. But she will never speak or see again....

When Sandra Ashville is found murdered in a sleepy town near Oakhurst, Detective Jo Fournier is first at the scene. Jo is shaken by the similarities between herself and the dead assistant district attorney, a dedicated woman with a heart for justice. And as she examines Sandra’s body, Jo discovers something that chills her to the bone: The bullet hole is covered by an intact blindfold. Why was Sandra only blindfolded after her death?

The very next morning Jo receives a shocking call. A judge has been brutally killed, before she too was blindfolded. Soon it becomes clear that the twisted serial killer is working with a deadly countdown: Every morning, another body will be found. Working around the clock, Jo makes an important breakthrough: All the victims are connected to the same murder trial. And Jo’s dear friend and partner Bob Arnett could be next....

With the next morning rapidly approaching, Jo and her team pull out all the stops to catch the killer. But when she uncovers a stain of corruption that includes Bob, Jo faces an impossible choice. Can she trust her partner, when the evidence suggests he turned a blind eye to a grave miscarriage of justice? And as the body count rises, can Jo catch the killer before it is too late for her oldest friend?

From USA Today best seller M.M. Chouinard, What They Saw is an utterly addictive serial killer thriller.
