A Clean Kill - Steven Konkoly

An FBI agent hunting a serial killer has to up his game when a trail of murders is not what it seems in a riveting thriller by Wall Street Journal bestselling author Steven Konkoly. Five dismembered bodies are found along the roadside, dumped in the middle of nowhere. This isn't new to Special Agent Garrett Mann. Head of ARTEMIS, a specialized FBI task force hell-bent on hunting down cartel-related killings in the Southwest, Mann has seen this before.
He and his team have been tracking similar kills along thousands of miles of rural roads running north, south, and back again. When the latest slaughter yields a key piece of evidence, Mann thinks he's found the killer and solved the case. That's when the nightmare begins.
From a lakeside Minnesota mansion to an abandoned CIA black site in New Mexico, the hunt is on. But the closer Mann gets to his prey, the deadlier the stakes become. This is no ordinary serial killer. He's not working alone-and the stakes go far beyond just preventing the serial killer's next massacre. What Mann unravels is a powerful and far-reaching conspiracy beyond his wildest imagination.
