From The Perry Mason TV Show Book (Revised)
A night at the theater proves fatal. The lights mysteriously go out during the dueling scene between Romeo and Paris. When the lights come back on, the audience is shocked to see that the leading man playing Romeo has been stabbed to death. Perry’s actor friend, Steve Brock, is accused of the murder, so the lawyer goes behind the scenes to investigate the cast of characters.

Perry decides to have the cast reenact the final scene that was played before “Romeo’s” death to upstage the killer. When the action begins, this play begins to look more like Macbeth than Romeo and Juliet.
