I have to say by Simenon standards this was bit of a clunker for me. The dialogue is far too clipped with everyone seemingly interrupting each other. The plot fails to engage and, due to the problems with the dialogue, a bit confusing. Maigret himself seems far too miserable and the setting has nothing to do with the Flemish parts of Belgium.
The best part about it is the stunning front cover, depicting a typical Northern Belgian bar with what looks like a freshly poured De Konick beer on the table. De Konick being one of the great 'city' beers, completely synonymous with it's home town Antwerp. If you have a chance to visit go and ask for a bolleke, which is the name of the glass De Konick is served in.
Great city and a great beer but unfortunately for me, a disappointing Maigret.
