***I haven't seen this episode yet, but will soon, as the UK Talking Pictures channel is showing this French version -- we saw last year (2022) the complete set of episodes of the BBC's 1960's Maigret -- with an acclaimed performance by Rupert Davies in the lead.
We've also seen the Michael Gambon Maigret, 2 series each of 6 episodes, all very well done on a bigger budget than the BBC ones (not difficult!), and the Gambon episodes DID include this one, set at the house of a dentist.
One of Maigret's underworld acquaintances reports finding a body, whilst attempting a burglary. As a murder trumps a burglary, Maigret sets out to make some enquiries.
The dentist (& his mother) seem quite sure that no burglary happened. But has he been doing some DIY repairs?! And has the wife really gone to visit someone back in Holland?
One thing I must do is correct the review by Dragonfroid, who says "search warrants do not exist in France!. Well, they may not be called that, but this is in Wikipedia :- In particular, except for crimes in flagrante delicto, law enforcement forces may not conduct searches or arrests without a specific commission from the investigative magistrate. Sounds quite like a search warrant then?!
***And NOW I have seen this one, second viewing of the Cremer Maigret, and it can be hard going! All done at a very leisurely pace (very French, lots of atmosphere, lots of brooding thoughtful looks!), with what frankly seemed some padding, to fill the time, an extra half-hour as opposed to the Gambon version (which told the story perfectly well).
Excellent acting though - this one had Michael Lonsdale (star of Day of the Jackal) as the dentist, superb as he staunchly denied all accusations, while seeing Maigret close the web around him (& his mother). A couple of oddities, absolutely no sight of Lucas (they used his office) that's very strange as the books all make clear HE is Maigret's R-H man. And Mrs Maigret appears ( a brief but nice portrayal) though she actually attends Maigret's OFFICE, which I think is unknown in the books I've read, and definitely never happens in the Davies and Gambon versions. What DID Lucas do to upset these producers?!!
