There are two types of Puzzle Lady puzzles, the ones she creates and the ones she does not. Cora creates the Sudoku puzzles. Her niece, Sherry Carter, creates the crossword puzzle, because Cora couldn’t create one to save her life.

The Sudoku puzzles in the books are created by Will Shortz, the crossword puzzle editor of the New York Times, and the author of his own very successful line of Sudoku books.

The crossword puzzles are created by New York Times constructors recommended by Will Shortz.

I am pleased to present a Sudoku from the Puzzle Lady mystery, Arsenic and Old Puzzles, created by Will Shortz, and a crossword from the Puzzle Lady mystery, $10,000 in Small, Unmarked Puzzles, created by Fred Piscop.
