Ah, the '70s. When we all pondered the nature of reality. Well, some of us, anyway. Keith Laumer certainly did, in what must be one of his odder concoctions. It begins with a private-eye being hired as bodyguard to a senator. Or so it seems. Pretty soon, we're having Groundhog Day on LSD. After that, things get weird. Not only is no one who he seems to be, no one is who he seems to be in dozens of different scenarios. Okay, I'm exaggerating. Not dozens, but a lot. Things happen, and then it turns out they didn't. Or did they? If you don't get hopelessly lost in all the twists and turns, you'll arrive at the end with everything all tied up neatly. Or is it? Maybe not.
There's an interesting story about the paperback publication of this book. Somehow the publisher (Berkley) switched Laumer's novel with The Man in Question by John Godey, so Night of Delusions appeared in the cover for the Godey book and vice versa. I have the corrected edition here, with the right book under the right cover.
