In Independence Day, the posse is hired by Wyatt Earp to maintain the peace during the centennial celebration of the United States. They simply can't go around gunning down troublemakers; they have to maintain proper decorum as a peace officer. There also seems tob e a brutal murderer going around town that they have to investigate.
The adventure can be run as a short one session adventure or can take several. The bad guy in it is difficult but easy to deal with; the ramifications of the posse's actions, however, can be more difficult then actually fighting the bad guy.
As with the other dime novels, I would have to highly recommend it.
Style: 4 (Classy and well done)
Substance: 5 (Excellent!)
