Bent Twig by Joe R. Lansdale
Hap Collins goes looking for this girlfriend's daughter, Tillie, but he knows he's going to have a rough going because Tillie is into having a rough-type of life and the associated rough individuals that are part of it. Luckily for Hap, his brother from a different mother Leonard shows up at the right time to save Hap and join the search for Tillie. The two raid a church used as front for a lowlife who claims the title of pastor to find Tillie. There are numerous rogues in this story, but Hap and Leonard are the most resourceful in getting this particular "job" accomplished.
