In this droll derivation of "Arsenic and Old Lace", former 1940s film ingénues Teresa Wright and Joan Leslie are cast as the spinsterish Appletree sisters, Cabot Cove's resident eccentrics. With the annual flower show coming up, it looks as though dear old Helen and Lillian Appletree are going to win first prize with their chrysanthemums, which have bloomed beautifully and beyond all expectations. What no one else in town knows is that the ladies have come upon a wonderful new "fertiziler"--namely, the body of one Morris Penroy (Henry Jones), whom they have buried beneath their flower bed. When a second corpse pops up at the Appletree house, Cabot Cove's new sheriff Mort Metzger (Ron Masak, making his first appearance in this recurring role) cannot help but suspect that the old biddies have committed murder--but as usual, Jessica (Angela Lansbury) has concluded that someone else is responsible.
