Heinlein

Okay. So I've read Stranger in a Strange Land and I'm reading The Moon is a Harsh Mistress currently. I love Heinlein because of the way he writes innocence. He annoys me by completely failing to write credible women. He's pretty heteronormative overall, really, but given the time in which he lived I can kind of overlook that.

But really, friends-list. Have you guys read a Heinlein book that had a single female character who could think? Seems to me that every time the woman (and for a good long while in these two books there's really just one) in the story is there to be the one who needs an explanation so that Heinlein's pet character (generally an awesome character, too, but definitely the author's self-insert--*cough*Jubal Harshaw*cough*) can explain to the pretty woman what sound and excellent plan the adults have come up with to save crafty men and lovable female dolts alike.

Women are always the last to know, and they seem to be present as a means for the men in the novel to prove how awesome they are. If Heinlein just wrote them like guys he'd be straight-on, because his male characters are still engaging for me.

Has anyone else noticed this? Heinlein's utter failure to grok women? Or is this not a general trend with him? I might just have picked two books that are giving me the wrong idea, but it seems like a hell of a coincidence.
