Solution to the last puzzle
Merry Christmas to all who celebrate! Here's a themeless for the occasion, as my gift to you. It's solvable with friends and family, or curled up next to a roaring fire with a warm blanket and the company of yourself. Whatever gets you in the ~spirit~
Also, my nine-year-old cousin saw me cluing the puzzle, and offered some clue suggestions in the process. He wants you to know that the clues for 29-Across, 55-Across, and 27-Down are all him. Kid's got a future in puzzles, I tell ya.
Hope you enjoy!
