Cattleman Protective Association Captain Boyd McMasters is sent to Silver Creek, Texas, to investigate a case of cattle rustling involving four prize bulls worth about $20,000. That's enough money to kill for, it seems, because someone keeps drawing a bead on McMasters every time he goes into town. When McMasters figures out who's behind it all, he's going to lay down the law.
A decent but unspectacular read. Lee Morgan--or whoever is behind the house name this time around--keeps up the range detective angle, this time with some valuable cattle having been stolen after they were sold off but before they could be delivered.
The resulting narrative is more Agatha Christie than it is Edge. McMasters get bush-whacked a number of times, but can't actually gun anyone down until the last pages, since obviously that's gonna be the guy who dunnit. It makes for a bit of a frustrating read, as does the tacked-on sex, which is clearly more of an obligation than a point of pride.
Martha shows up again, giving some continuity from the last book, but also showing why most Westerns don't have the hero in an on-again off-again relationship with a girl who he can't quite figure out. It's like a Dr. Quinn Medicine Woman episode, as told from the perspective of the guy who dates Dr. Quinn. Go out and rob a bank or something, dude, it's called Silver Creek Showdown, not Silver Creek Situationship.
I maintain my position that it's weird to have a pulp book where the cover has a man showing more cleavage than the lady. Cover them up, slut.
