    • The title of the episode alludes to the nursery rhyme beginning Mary, Mary, quite contrary, how does your garden grow? On his first visit to Miss Barrowby's, Poirot finds her silver bell buried in a flower bed which is edged with oyster shells and he quotes the line "With silver bells and cockle shells all in a row." The bell proves to have been buried by Mary Delafontaine, who poisoned her aunt with the help of the oysters.
