Normal travelers need not stop at the Valhalla Motel—the place is strictly for the sexually adventurous, including a newlywed couple that wants to be filmed having sex, an older woman who likes teen boys, a masochist who gets off on pain inflicted by a masseur, and of course the usual assortment of lesbians and bisexuals. Building a sleaze novel around a motel and the manager’s efforts to discreetly please the customers is a pretty full concept for a book, but author Richard Donalds also saved a little creativity for efforts such as Not Since Eve and Something Special. Those books, as well as Sign Here for Sin, were published in 1963, but only the latter has brilliant Paul Rader cover art. It’s one of his better efforts and it makes the book highly collectible.
