Much Ado About Muffin: Merry Muffin Mystery, Book 4

Opera singer Roma Toscano may have a crippling case of stage fright, but she certainly is stirring up drama in Autumn Vale, New York, as she prepares for an upcoming performance at Merry's Wynter Castle. With her flamboyant style and flirtatious personality, Roma attracts fans as well as critics, including the town's postmistress - and Merry's bitter foe - Minnie Urqhart.

But Roma and Minnie's heated rivalry goes cold after Merry discovers Minnie dead at the post office. While every clue seems to be another ingredient in the investigation of Roma, Merry thinks the case is half-baked, and she's eager to get her mitts on the real killer.
