PBS must be running out of Miss Marple novels to film so they’ve turned to Miss Marple short stories. “The Blue Geranium” was published in The Tuesday Club Murders (aka, The Thirteen Problems) in 1932. A cranky hypochondriac, Mrs. Pritchard, is told by a fortune-teller that “a blue geranium means death.” And, sure enough, Mr. Pritchard then dies from a gas leak with a blue geranium nearby. Miss Marple investigates and solves the murder. Masterpiece Theater Mystery will be broadcasting “The Blue Geranium” tonight. I’ll be curious to see how a 12-page short story is puffed up to fill 90-minutes of television drama.
