This is #3 of our "Curious Conundrums" series (named by Don G, by the way). Constructed by our own Marti DuGuay-Carpenter.

Marti mentioned that Rich really liked this theme but had to let it go after some fact-check. I like the surprising factor of the unifier, clean grid and the overall light & fun clues (favorite is 9D).

Do let us have your feedback. It's how we improve.
