The Devil's Collector — J.R. Roberts

KILL LIST

When Clint Adams walks into a saloon in Danehill, Arizona, all he wants is a cold beer, but his drink comes with a side of trouble. Riding into town after him is Jack Sonnet, a man who wants revenge against the four criminals who shot his brother--one of whom happens to be in the saloon.

Clint learns that Jack is the grandson of an old friend, and he offers to watch the young man's back--not just for the men he's fixing to kill but for all the trouble that will follow...
