Can't find any information about Oh, It Feels Like Dying, a novel by someone called J.J. Madison. It was reprinted several times through the 1970s under the wildly imaginative title The Thing, with requisite references to The Exorcist and The Other on the covers. In 1978, the publisher simply copped an image of actress Anouska Hempel from Hammer's Scars of Dracula(1970), subbing a lurid tagline for the "glittering world" one of the first two paperbacks. According to Vault of Evil, whatever the title it is essentially only a (terrible, at that) porno novel dressed up as horror. Alas, what could have been!
