There are Old West heroes of courage and conviction—and then there are the Sidewinders. Bullets fly in this rowdy adventure from the bestselling authors.

William W. Johnstone and J.A. Johnstone bring back those beloved, bumbling cowboys, Bo Creel and Scratch Morton. As usual, despite their best efforts, deep trouble has a way of tracking them down . . .
Knocking on Trouble's Door
There's nothing like family. At least that's what people say. But when Bo and Scratch come home to Bear Creek for a long-overdue visit, Bo's family kindly invites him to turn around and leave. His old friends and neighbors turn tail and run when they see him. Next thing he knows, he's in jail for the brutal murder of two saloon girls in neighboring Cottonwood. Unfortunately, the real killer looks astonishingly like Bo. Now, with his buddy in jail, Scratch needs to ride to the rescue, if he can escape the clutches of the beautiful assistant to a traveling snake oil salesman. With Bear Creek in an uproar, a man with Bo Creel's face and body is about to kill again. And the worst is still hovering on the horizon: a family secret that could turn Bo's hair bone-white.
