One of the most outrageous films from Chabrol's first 'commercial' period, before Les Biches renewed critical interest in the wayward New Wave instigator. Released here cut, dubbed and lacking an essential prologue featuring a mad illusionist, lumbered with the title Who's Got the Black Box? in the States, it's a wonderfully maddening mix of clattering allusions (to Greek tragedy and Hitchcock), characteristic black humour, and stunning visual irrelevancies, all poured into the deliberately banal mould of the spy thriller. 'I do not ask you to believe it, but I suggest that you dream about it' runs the film's opening epigraph. 'The silliness was more important than the spying' runs Chabrol's own retrospective line.
