I wanted for quite a while to read a Maigret novel and the only ebook in the series my library has was this one. Not the first in the series (it is in fact number 30) but it is Maigret's first case since when he was only a secretary at a local police station. A rich weird family in Paris, a shot in the night heard by a passerby, a mystery that Maigret will have to solve without any assistance from his police chief or colleagues. An enjoyable read.
