It’s the holiday season, and high school show choir coach Paige Marshall may be on the verge of her first big break as an opera singer. But she probably shouldn’t quit her day job just yet . . . 

A part to kill for singing in a production of the Messiah and rehearsing her show choir for a holiday concert may be more than Paige can Handel. Not only does she have to contend with the overblown ego of world-renowned tenor David Richard, she now has to quickly revamp the show choir’s number, since not one but two other high schools are performing the same song for the quickly approaching competition season. 

The tempestuous tenor may have a voice to die for, but when he drops dead during rehearsal after drinking poisoned water, Paige has to compose herself and once again solo as a sleuth to find a killer who’s no choirboy . . .
