James Qwilleran and his famous felines, Koko and Yum Yum, are back for another mystery-solving stint in the beloved bestselling Cat Who . . . series. The good people of Pickax are agog with anticipation: Not only is the new bookstore, The Pirate's Chest, about to open, but the Theatre Club is set to perform Oscar Wilde's The Importance of Being Earnest. The play does not continue past opening night, however, for a member of the cast is killed in a car accident . . . or was it an accident? Koko seems to suspect otherwise, and Qwill and his clever cats have their work cut out for them.
