Black Diamond Western #32 (1949)

Black Diamond tracks down a gang of outlaws impersonating Native Americans in Masonville who have been using the deception to rob and kill townspeople, including stealing valuable suits. After a shootout on the main street, Black Diamond confronts the masked ringleader and defeats him, causing the gang members to scatter. When Siouxindians arrive seeking justice for the crimes committed under their name, Black Diamond assures them that the fraudulent gang has been stopped, and the stolen goods are recovered as proof of the scheme's exposure.
