This episode marks the first appearance of the obsequious Herbert Viola (Curtis Armstrong), who would develop into both a godsend and a pain in the neck for detectives David (Bruce Willis) and Maddie (Cybill Shepherd), not to mention their spacey secretary Agnes Dipesto (Allyce Beasley). The story concerns a married woman named Gail Woodley (Brooke Bundy) who has been carrying on an illicit romance by mail. She wants David to convince her rather unstable "lover" that the affair is over--but it ain't that easy. Watch for an unbilled "fall-down" appearance by C. Thomas Howell).
