This episode is obviously inspired by the film "Arsenic and Old Lace". The film centers around two spinster sisters who murder lonely men and bury them in their cellar. The TV episode also features two spinster sisters who bury the bodies of two men in their flowerbed. However, in this story the sisters are suspected of their deaths, but prove to be innocent of the charges.
