S4, E14: With her parents (recurring guest stars FRANCES STERNHAGEN and BARRY CORBIN) in town, Brenda is busy preparing for her upcoming wedding.

The case becomes a race against time when the police realize there may be more than one killing involved. Tagging along for the investigation is Fritz's vegan sister, Claire (recurring guest star AMY SEDARIS - "Strangers with Candy"), who fancies herself a psychic -- or, as she says, "an intuitionist."
