Murder for Choir by Joelle Charbonneau

13110452  First in a series and a new to me author, this A Glee Club Mystery seems like a Glee TV show spin-off.  Paige Marshall is an aspiring Opera singer who has landed home between professional gigs and is currently teaching a high school competitive show choir.  The atmosphere is cutthroat among the teaching staff and the students, eventually the pressure blows and someone ends up dead.  Paige discovers the body and puts herself squarely in the sights of a killer.  Fans of the TV show will probably enjoy this musical competition themed cozy.
