Solving the Mystery with Clues.
John Ewbank, a British science writer, created an American-style crossword puzzle for The New York Times that features anapodoton, a rhetorical device where the main clause of a phrase is implied by a subclause. The theme consists of six entries that trail off into nothing, prompting solvers to complete the idiomatic phrases. The puzzle includes clues such as "When in Rome" and "Speak of the devil."
