The Puzzle Lady embarks on another adventure involving one classic movie and featuring new puzzles by Will Shortz  When an elderly boarder at a Bakerhaven bed-and-breakfast drops dead during afternoon tea, there's nothing particularly suspicious about it—except for the Sudoku in his jacket pocket. But when a second body turns up in the window seat and an autopsy shows both men were poisoned with elderberry wine, the Puzzle Lady suspects she's dealing with a cold-blooded killer who for some reason is copying the Cary Grant movie Arsenic and Old Lace, in which two old ladies who run a boarding house poison elderly widowers and bury them in the basement. More murders, more puzzles, and a grave dug in the cellar seem to cement the theory.
