Margery Blandon has led an upright, principled life guided by the wisdom of desktop calenders. Now she suspects that her firstborn, Walter, her champion and closest ally, has betrayed her. She suspects Morris, her second son, might have committed a crime, and that her only daughter, Judith, is trying to kill her. Then there's Pat, her lifelong neighbour and enemy, now demented, who possibly knows the truth about what went wrong. Should she throw herself from the 43rd floor of the Tropic Hotel, or should she abandon everything she believes and embrace her enemy for the sake of what's right?.
