In Irma la Douce, what is Jack Lemmon's policeman character named?

In Irma la Douce, Jack Lemmon’s policeman character is named Nestor Patou.

Nestor is introduced as an honest Paris policeman transferred from the Bois de Boulogne to the busier Les Halles district. During a raid on a brothel, he unknowingly arrests his own police chief, is dismissed from the force, and becomes entangled with Irma, a popular prostitute played by Shirley MacLaine.

To keep Irma from working as a prostitute, Nestor invents the wealthy English client Lord X. The disguise creates the film’s central comic complication: Nestor must secretly finance and maintain a fictional identity while living with Irma. His former police identity remains important as the plot spirals into mistaken assumptions about murder and disappearance.

The 1963 film was directed by Billy Wilder and adapted from the French stage musical by Alexandre Breffort and Marguerite Monnot. Nestor Patou is sometimes confused with the other names in the options: Hippolyte is Irma’s abusive former pimp, while Harry Hinkle and Claude Chavasse are characters from different Lemmon films.
