read moreMany crosswords have themes involving a uniform feature of some or all of the clues (length or starting letter or spelled-out message, e.g.). As a rule, these clue-based themes tend to be ornamental. Solvers need not discover them in order to finish the puzzle; oftentimes they don't even notice such themes unless they're specifically pointed out.
I thought it would be fun to try to build a crossword with the opposite approach: the solver would have to discern the clues' thematic feature *before* she could make progress. Each clue would be a microcosm of the overarching theme, and deciphering just one small riddle from anywhere within the grid would allow the solver to unlock the whole thing. A kind of fractal puzzle, if you will.
There were two requirements of the deleted letter. In the first place, it had to be very common. The deleted letter also needed to allow the revealer to be clued like everything else, so that the theme would be embedded within the cluing itself. When I saw that "hint" would reduce to "hit," and that the revealer could be written as though it were a four-part song, I settled on N. Because of its frequent usage in consonants clusters N worked out well.
The major difficulty of construction was that unless an entry was an everyday noun or verb, it was unlikely that it would clue satisfactorily. Entries such as QUASI, LOSES IT and AXON were all chosen specifically for their tricky possibilities. I scrapped a previous grid pattern and its half-clued fill when it got to a point where both ROSE RED and CERISE were necessary and I couldn't figured out how to clue them without repeating the same word containing N.
The usual thank yous and kudos go out to Will Shortz and his unheralded band of behind-the-scenes assistants. Changing my POET clue from [Date, e.g.] to [Doe, e.g.] is so, so cunning. Their ERSATZ clue is beautiful, and is one of my favorites.
*N.B. Ashish Vengsarkar and Narayan Venkatasubramanyan pulled off a similar (and brilliant) theme with TEN ORS back on December 6, 2008. In his Wordplay notes Mr. Vengsarkar mentions the difficult time he had persuading Will to accept the puzzle. As this puzzle encountered no such resistance, I owe them a debt of gratitude. I hope this puzzle in some small way measures up.
