Let him who hath understanding reckon the number of the beast...

I’ve never read Robert A. Heinlein’s 1980 science fiction novel The Number of the Beast, but I am quite familiar with British heavy metal band Iron Maiden’s classic song “The Number of the Beast,” which was released in 1982. Here is the official Maiden video for "the Beast," complete with a clip from the SF film The Angry Red Planet (1959).



Anyone see a link to the Heinlein novel?
