There just isn't much to this one. It's not very memorable and what is memorable isn't for great reasons.
Slocum is on his way to help out an old friend (Slocum's old friends, like people who invite Jessica Fletcher to a wedding, are never in for an easy time) when he's waylaid by vigilantes that are keeping the local hanging tree well-tended with horses thieves and cattle rustlers--or so they claim. Led by Mysterious Bill Dime (huh?), they want Slocum to lead them to his friend, Jeremy Patches (what?). Another character is T.P. Daventry, so pretty much all the nouns are cursed in this one.
It's all part of an elaborate plot for the bad guys' to get their hands on Patches' land, which they will then turn into an Indian reservation so they can get the land the Indians presently have. There, see, nothing like the usual land-grab plots *or* the stoking an Indian uprising plots. This is a land-grab to stoke an Indian uprising plot. Totally different.
The whole thing has too many characters swanning about (like I said, we have a whole Indian tribe *and* the old friend Slocum has to help), a plot that never quite pans out, and an odd tendency to start every sex scene at the end, just after a scene change, which really gives you whiplash. Once or twice I thought there was a missing page.
