The Affair at the Victory Ball (S03E10)

At the extravagant Victory Ball, a costume event where guests don famous personas, Poirot arrives in his own distinguished attire. The celebration takes a dark turn when two individuals from a group of six, who are dressed as characters from classic Italian comedy, are discovered dead. Teaming up with Chief Inspector Japp, Poirot delves into the mystery, focusing on pinpointing the time of death and uncovering a disguised intruder among the attendees. In a dramatic twist, Poirot broadcasts the revelation of the murderer during a live segment on BBC radio.
