OK, this may not the ONLY good, solid episode from season 4, but just about. (There are two or three more, perhaps, but none as competent as this).
Pepper and Crowley go after a wife-beater and discover his FIRST wife, whom the second wife (Dee Wallace) didn't know existed, has been missing for years.
So, having no other option, Pepper goes to the nearest nightclub and starts dancing.
