Inspector Lognon – a plain-clothes detective with a reputation for misfortune – is shot in the street with the word ‘ghost’ on his lips. It soon emerges that he spent the night in the apartment of a beautiful young woman, who has since vanished. While the injured man fights for his life in hospital, Chief Superintendent Maigret discovers that the hapless Inspector may finally have been on to something big. And when he encounters suave art dealer Norris Jonker and his glamorous wife Mirella, Maigret begins to wonder if their strange lifestyle is the reason for Lognon’s presence on the Avenue Junot.

In Maigret and the Ghost, Simenon’s tenacious detective is perplexed by a constant stream of conflicting evidence as he explores the underground world of art collecting.
