One wonders what James Hadley Chase thought of this adaptation of 'Tiger by the Tail' directed by Julien Duvivier. The respectable banker in the book has here become a lovable, bumbling clarinettist in what is essentially a star vehicle for the marvellous Fernandel but even he cannot keep this afloat. John McGiver in this his first film steals his scenes as a dodgy art dealer and Bernard Blier has a thankless part as a nosey neighbour who discovers that curiosity kills the cat. This is a film that cannot make up its mind whether to be a comedy thriller or film noir and succeeds as neither. One of Duvivier's duds.
