Valley of Skulls — Jake Logan

When Slocum teams up with an old friend, they add a few more skulls to the valley!

Slocum just got into Denver, but his long-awaited night on the town took a sharp and unexpected turn when he ran into his old friend Lemuel Parsons. And when Lem and the distraught young woman by his side told Slocum about the violent kidnapping of her father and brother, he knew what he'd be doing in Denver -- looking for the bastards who did it.
 
Now Slocum's teamed up with Lem in a hunt for the kidnappers who have been pulling the same scheme all over town -- muscling everyone off their land. And when their search leads them to the perpetrators, Slocum and Lem find themselves mixed up in a situation even stickier than they could have imagined…
