Query: Literature, this is not...

I admit, I'm a fan of STRANGER IN A STRANGE LAND and FRIDAY. That's about it. TIME ENOUGH FOR LOVE falls as a guilty pleasure. But this isn't good literature, it is not good science-fiction literature, and it's one bad book. The plot actually does start out promising. At first it seems to be a murder mystery that has more than 1 implication to the rest of the world. Then Heinlein looses it. He goes back to ...THE NUMBER OF THE BEAST ... So from that point forward the plot just goes downhill, nonsensical, want-to-be symbolical but just fall short dime store novel. I really had high hopes for it as it DOES START OUT WELL but toward the middle and end it just makes one wonder if Heinlein's faculties were all there.
