The title characters in this episode of Bonanza are the Lowell sisters: Ara (Vera Miles, Gabrielle (Lyn Edgington, Lorraine (Madeline Mack) and Heather (Melinda Plowman). Having inherited their uncle's ranch, the ladies arrive in Virginia City to discover that all they've received is a pile of debts and a whopping bill for back taxes. Ben Cartwright steps in to save the sisters from financial ruin, earning the undying gratitude of three of the ladies-and the suspicions of Ara, who is certain that Ben has an ulterior motive. David Rose's background music for this episode includes what would evolve into the theme for the later David Dortort-produced western series The High Chaparral. Originally telecast on October 30, 1966, "Four Sisters from Boston" was written by John M. Chester. ~ Hal Erickson, Rovi
