This is the third Agatha Christie adaptation (and second featuring Tommy and Tuppence) by Pascal Thomas and his best to-date.
Thomas is at the top of his art when he can combine mystery and sophisticated comedy, which is the case once again in 'Le Crime est notre affaire', a loose adaptation of '4.50 From Paddington' in which Miss Marple has been replaced by Tommy and Tuppence. The mystery is exciting (a murder without a corpse) but as was the case with 'Mon petit doigt m'a dit' the pleasure also comes from the offbeat atmosphere, the strange locations , the impeccable cast with the right talented actor or actress in the right place (special kudos to Claude Rich as the old stingy pain in the neck).
The icing on the cake is the brilliant dialog, filled with witty one-liners, exchanged by a wonderful couple of modern Myrna Loy-William Powells (I mean of course the marvelous Catherine Frot and André Dussolier), as the eccentric bickering-but-loving couple of amateur sleuths.
An entertainment of very good quality.
