Movie: The Long Goodbye (1973)
It seems like private eyes exist exclusively to get duped by dashing duplicitous wives. P.I. Phillip Marlowe (Elliot Gould) doesn't make the classic mistake of falling into bed with Eileen, but that's about the only error in judgment he avoids when she hires him to find her missing, alcoholic husband. Naturally, the investigation plays out exactly as Eileen wants it to. Which is to say that in noirs, P.I.'s are the next best thing to divorce lawyers, only with half the fee and double the accountability.
