The Last Confession, press notes state, "delves into the most highly guarded institution in the world to explore the mystery shrouding the sudden death of Pope John Paul I in 1978. Found dead just 33 days after being elected, suspicions were aroused when it was revealed that, on the evening before his death, the new Pope had warned three of his most influential but hostile Cardinals that they would be replaced. The Vatican refused to conduct an official investigation into the death. Cardinal Benelli was the only one to challenge the dead Pope’s enemies and to launch his own investigation."

Directed by Chichester Festival artistic director Jonathan Church, the production features a set by William Dudley, lighting by Peter Mumford and costumes by Fotini Dimou. Music is composed by Dominic Muldowney with sound design by Chris Cronin.

Performances continue through June 1.
