A minor but nonetheless interesting director ,Georges Lacombe made at least two very good movies " Pays Sans Etoiles " and "Le Dernier Des Six ";with screenplays written by Pierre Very or the master HG Clouzot (even Tarentino pays a tribute to two of his movies in "Inglourious Basterds"),you play safe anyway.
Like the two aforementioned works ,"Monsieur La Souris" is based on a great writer's book ,Georges Simenon adapted by Marcel Achard.For all that ,the story is not that exciting,being a derivative whodunit with an unexpected twist a la Agatha Christie .The reason why you would watch this is Raimu.Thanks to his huge talent,you never yawn from boredom:he portrays a tramp -his nickname is "La Souris" (the mouse)- on the street ,who gets involved in a criminal affair and plays the occasional detective :he is better at it than the Police (Poirot and Japp,no less).
Raimu's final (very long)lines are priceless and are worth the price of admission alone.
