"The Blue Geranium." Mrs Pritchard, a bedridden woman with an interest in tarot cards, is visited by a fortuneteller who warns her against the color blue. Blue primroses mean caution, blue hollyhocks are a sign of danger, and blue geraniums will mean death for her. When the warnings begin to appear as if by magic, Mrs Pritchard is terrified. Miss Marple and Mabel investigate.
