The Vengeance of The Invisible Man

The Universal Library is a series of horror/comedy books inspired by classic horror films of the 1930s and 40s. The stories are set in the present day but with a classic feel, tongue in cheek delivery and many references to the original films and other horror movies for film fans to spot. You don't have to have read the first two books to enjoy this one (although you may get more out of it as characters do recur, weaving in and out of the series).
Christmas in Cambridge and the must have gift is new book, The Life of an Invisible Man, thanks to an impressive marketing campaign by its author, known only as The Invisible Man. He’s been pulling off impossible stunts around his hometown, making him an overnight celebrity and media sensation. No one thinks this is anything other than a clever stage magician or a computer wizard posting videos to YouTube. Or at least, almost no one. Amelia Evans was there for the book’s extraordinary launch and she doesn’t think this is a trick. When things turn violent, Amelia calls in some old friends to help. Elsewhere in Cambridge, Inspector Clive Harrigan is starting his last month on the force before retirement. The last thing he needs is a serial killer murdering University Professors, especially one who seems able to walk past people and security cameras unnoticed. Is there a connection? Is the Invisible Man a dangerous serial killer? Or does he just want to be seen?
