Syms Thorley is a B-list horror movie actor, who specializes in playing The Monster in various 1930s and 1940s horror movies. Mummies, Frankensteinian monsters, and other prosthetics-and-makeup-heavy characters are his specialty - and he has the shamble, the limping walk down pat for every character. If you haven't guessed his role in the story yet, look closely at the cover art. That's it.
This was a somewhat short, very witty, and quite entertaining read. It reminded me a bit of Kurt Vonnegut's writing style, except less ADHD-like, a more focused narrative that skipped from flashback (in 1945) to present-tense and -time narration (pretty much every chapter begins with our narrator telling us what distraction occurred when he wrote the previous chapter).
(And by the way, I lifted the picture from this thing, which is a far more detailed review-like-thing with a much better exploration of this book's themes. Click on the link!)
