Henri LeFort, a police inspector suffering from extreme noise sensitivity, is plunged into intrigue when the occupying Nazis deliver him an ultimatum: Solve the murder of a German offcial or suffer fatal consequences. Given just a week to catch the killer and forbidden from entering the Louvre where the murder took place, LeFort suspects his death is imminent. The investigation leads him to Pablo Picasso and Marie Bonaparte, a psychoanalyst who's keen to learn the cause of his aversion to sound. Rich characterization and quirky humor enliven this unconventional whodunit.
