Nightriders of the Double Spur

If the Triple B ranch is rustling cattle from the Double Spur, then why is the Triple B the only one losing Cattle? It makes no sense to Tom Grigsby, but the owner of the Double Spur is honest. Grigsby should know; the man raised him. On the other hand, the Double Spur has all new ranch hands and no one appears to know why they are riding the range at night. Dugan is convinced that his ranch hands are all loyal. His daughter isn't so sure. Grigsby was invited by Dugan to investigate the situation and he figures he owes Dugan something. He's ready to stop running all over the country solving problems for everyone else, but this is personal…maybe too personal. People are seeing him only as a hired gun and he wants to leave a better legacy than that. Grigsby sets out one last time to find out who is rustling cattle and why. It isn't what he wants to do, but it's what he does best. If he's going to get any cooperation, he'll have to contribute a little information about why he qualifies for the job. That might put him in more danger, but he has a plan. He has a hunch who is doing the rustling, but he'll have to scour the valley to prove it.
