Character is everything in this episode. Maigret divines personalities and motivations to gradually unfold the psychological currents which have led to the murder of the mistress of a brilliant but amoral brain surgeon. Maigret himself is very much under Simenon's microscope in this one, and it's been said that Maigret and the surgeon are starkly reflected aspects of Georges himself, which is somewhat disturbing, come to think of it. 4.5 ⭐
