The Catalog Woman Lawman : Season 4 Episode 8

When one of Laramie's citizens disappears the day after his wedding to a woman he met through a marriage catalog, Dan does some investigating. Learning that several other men have also disappeared after marrying someone from that agency, he decides to try to flush her out by posing as an eligible bachelor, Arthur Daniels. Lily at first thinks it's funny, but gets serious (and jealous) once Johnny points out that this could be for real - or even fatal.
