To his parishioners, minister Matt Baker seemed a pious and good man. To his wife, Kari, he was a devoted husband and caring father. Always sunny and vivacious, Kari never questioned their frequent relocations from one small Texas Baptist church to another. Even when tragedy struck, Kari remained strong—until one day, inexplicably, she took her own life.

To friends and family, Kari's suicide made no sense—and they struggled with questions they couldn't answer. Why couldn't Matt hold a job with any one church? Why did he cut off all contact with Kari's devastated parents soon after her death? And who was the blond companion he began appearing with just days after the funeral? But it would take a team of investigators and dogged determination to bring Matt Baker's dark secrets to light—revealing a shocking history of lies, infidelity, cruelty, and sexual obsession that may have led a serial predator cloaked in God's word to commit murder.
