Script Swap by Gregory Ashe

They say the show must go on. Thank goodness for intermission.

Dashiell Dawson Dane isn’t thrilled that a new play at the community theater is based (however loosely) on his life. But when Dash’s friend Fox asks him to attend opening night, things take a strange turn: the actor playing Dash’s role seems to have been given a different script. Even stranger, the new lines trigger a bizarre response from the rest of the cast and crew—right before the lights go out and the box office is robbed.
At Fox’s request, Dash agrees to investigate, but he’s surprised to discover that everyone at the theater seems more preoccupied with the altered (and now missing) script than with the robbery. And when one of the actors is murdered in what appears to be a burglary gone wrong, Dash is sure there’s something much darker afoot.

But someone is determined to keep the truth from coming out, and Dash will have to navigate aging starlets, a disgruntled custodian, and a reclusive stage manager—among others—to catch the killer before they can strike again.
