Maigret and Monsieur Charles: Inspector Maigret, Book 75 (Unabridged‪)‬

He needed to get out of his office, soak up the atmosphere and discover different worlds with each new investigation. He needed the cafés and bars where he so often ended up waiting, at the counter, drinking a beer or a calvados depending on the circumstances. 

He needed to do battle patiently in his office with a suspect who refused to talk and sometimes, after hours and hours, he'd obtain a dramatic confession. 

In Simenon's final novel featuring Inspector Maigret, the famous detective reaches a pivotal moment in his career, contemplating his past and future as he delves into the Paris underworld one last time to investigate the case of a missing lawyer.
