S4·E20 The Night of the Diva

West meets up with Gordon, who has just arrived in New Orleans with a famous Italian diva and niece of the ambassador on his arm, an escort urged by President Grant. West agrees to substitute as the lady's guardian for her appearance that evening at the opera, but the performance is interrupted when Montebello's would-be kidnappers bring down the curtain and West jumps into the fray. Discovering that sereral divas had recently disappeared in New Orleans, the agents must rush to unravel a plot involving the secret Order of Lucia and reveal who among their new acquaintances is playing a role on and off the stage.
