Face Of The Devil — John Rose Putnam

When Lacey showed up in Hangtown Tom was smitten. She was looking for a Pa who'd come to the mines and disappeared. Tom had to help her, but when somebody shot him things went south in a hurry. He'd learned her pa was an army officer looking for turncoats from the Mexican War. Tom had stuck his nose deep into the evil skullduggery of some pretty bad men. If he didn't find her pa soon the next goose cooked could be hers. That notion chilled him to the bone.
