Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

This movie feels like it was made purely to piss off people who want good shows

Blistering performances.

Through painfully honest and emotional moments, the movie becomes irresistibly relatable

A chemist is working on a very important and secret new formula in a quite isolated country house. He believes someone is wanting to rob this formula and informs a friend, who is a detective. One night when several guests are in the house, the formula is stolen indeed and the chemist is about to be poisoned with a drug out of a lacquered box... Danielle Darrieux is smart and funny and René Alexandre plays properly his part. But the name of the detective is not Poirot. You'll find some suspense and a bit of espionage in this "huis-clos" adapted from A. Christie's play Black Coffee. The movie follows all the rules of the genre, but I wouldn't say the plot and the detective's deductions are really mesmerizing.
