Fängelsemysteriet The Prison Mystery

The JerryMaya Detective Agency #24

A play at Valleby prison have barely had its premiere when the actors disappear without a trace. Fortunately, Jerry and Maya are in the salon. The priest sets up “Hamlet” at Valleby prison. He wants to cheer up the inmates with an exciting play about murder and betrayal in which the three roles are played by prisoners. On the opening night, the expectant audience pours in, almost everyone in Valleby is there! But as soon as the show begins, the actors behave fully: The King jumps up and down from a gap in the stage floor, Hamlet throws the skull high into the air and Ophelia strikes somersaults. Some are horrified but most laugh, and when the curtain slides back, the audience stands up and claps. But despite all the applause, the actors never show up on stage again. Eventually, the priest pulls off the curtain. A terrible sight meets the audience…
