Maigret S'Amuse and Maigrez Chez le Coroner by Georges Simenon

I recently spotted this pair of French editions of two Inspector Maigret novels by Georges Simenon, and even though I don't know the language I loved the cover art, not to mention the coordinating aspect, so much that I couldn't help buying them. The iconic silhouette of the pipe, the man on the back, the rings of smoke. Maybe I'll teach myself French so I can read them. (Probably not.)

If you open the book and lay it face down it looks like Maigret is smoking his pipe. Pretty awesome.
