Blame this one (too) on Ian Fleming, advised Kingsley Amis in The James Bond Dossier (1965).

He evolved something approaching a formula for the presentation of Bond’s fair quarry. Its most noticeable feature is that, so to speak, the given girl appears in the first place … she is going to turn up. This is a convention, and as usual with conventions there’s not much use arguing with people who dislike it. Either you smile appreciatively and nudge your neighbor and lean forward when — say — the saloon goes quiet as new marshal and badman confront each other, or you groan and swear. If the second, you don’t like Westerns, and perhaps would be best advised to avoid them.
