Hugo Santiago made an interesting if minor little movie in the late seventies called "écoute voir" where Catherine Deneuve played a private eye dressed like Marlowe.

Here we go again.Another long-haired private eye,with a long gray beard, investigates a shady rich person's death.This is the beginning of an interminable story,extremely boring,with an exasperating voice-over-you might understand why at the end-.A lotta nudities.Cat Stevens's song "Lady D'Arbanville" whose connection with the movie escapes me.And Santiago's fixation about Jules Verne: (which was already present in "écoute voir" and its mysterious ray)the Nemo family.

If you can watch it till its end,congratulations!
