Investigator Cassie Dewell is on the trail of the Lizard King, in the series that inspired Big Sky. PARADISE VALLEY... THE END OF THE ROAD. For three years, Chief Investigator Cassie Dewell has been hunting the Lizard King. This time, the trap is set and she's sure she'll catch him. But when the plan fails, and three policemen die in the chaos, Cassie loses her job. But she won't - she can't - give up the hunt. Then two teenage boys go missing and Cassie takes to the road. A road from which, quite possibly, there is no return. A road that ends in Paradise Valley.

Investigator Cassie Dewell's three-year hunt for the serial killer known as 'The Lizard King' comes to a climax.

After a heart-in-mouth opening sequence, you're along for the ride across North Dakota and Montana and into the heart of an American nightmare. Breathtakingly good
