SEASON 3, EPISODE 319 - A pregnant woman researching her family history realizes that her great-grandmother, Violet Holley (Allison Miller), died in an unsolved murder. Rush tackles the 1929 case, her oldest to date, but she finds only a few notes revealing that underprivileged Violet had become pregnant by a wealthy man, Nick Bartleby (Tommy Dewey). The recollections of those suspects who are still alive cannot be considered reliable, but Rush does locate Nick's great-grandson and discovers recordings that might lead her in the direction of the murderer. Meanwhile, Rush's mother, Ellen (Meredith Baxter - ""Family Ties""), announces that she is engaged and wants Rush to attend the wedding. June Lockhart (""Lassie,"" ""Lost in Space"") guest stars as Caroline Bartleby, Nick's younger sister.
