When Benny Southstreet, a small-time hustler with a big-time gift for constructing crosswords, accuses Cora of stealing one of his creations, it’s clearly a case of mistaken identity…until Cora’s own attorney files a plagiarism suit against her. To add to the enigma, when Benny is found dead, the police charge Cora with his murder!

At the heart of the matter is the not-so-little white lie Cora has been living for years: assuming the grandmotherly public face of her publicity-shy niece Sherry, who designs crossword puzzles and publishes them under Cora’s name—aka the Puzzle Lady. It turns out that Sherry’s and Benny’s cruciverbalist paths had recently crossed, resulting in the current incriminating conundrum.

As if Sherry’s wedding engagement jitters and a nasty battle over missing antique chairs weren’t enough to deal with, now Cora has to solve the ultimate mystery: how to keep the secret of her identity without losing her life. Because not only does all evidence point to Cora, but someone seems to want her dead. It looks like a riddle with no answer. Luckily for Cora and Sherry, that’s their favorite kind!
