This is a review of "Maigret voyage", which is included in this volume.

Maigret is called to a Parisian luxury hotel where a famous millionaire has been murdered while taking a bath in his hotel room. A few rooms further down, his lover had spent the night and is gone in the morning. Maigret starts the chase and thus we travel to Nice with him, and further on to Monte Carlo and Lausanne, exploring the world of the rich and famous where Maigret does not feel at home at all.
The contrast this setting provides is very interesting: The luxurious and pompous world of millionaires and film stars opposed to the seedier sides of Paris, Maigret's down to earth ways and his calm, no-nonsense approach to work.
The case could have been a bit more interesting and I felt like the solution was a bit too easy, but I am looking forward to reading more Maigret novels!
