Till the Clown Sings: a Final Curtain Cozy Mystery in Bloomington, MN

The Opera's Diva Is Dead!
Before
the fat lady sang.
Assistant Stage Manager Jenny Caruthers
survived the opera cast's egos for four weeks of rehearsals, only to have the nightmare diva miss the final rehearsal curtain call. Why? She's dead on the backstage floor. Very annoying.
Did the fat lady die on Jenny's watch from a heart attack, general nastiness, or was there more to the scene than hit the stage? She doesn't lack for suspects.
The diva's moody tenor husband? The soprano who envied the diva's fame? The well-built baritone with nefarious plans of his own?
Jenny must unravel the mystery before the clown sings and the final curtain falls.
