I have no idea, but the book doesn't seem to indicate it's a tie-in with a TV program. The Germans have or had a couple of digest size magazines that reprint some American books along with domestic books. Some are romance, others are horror, and other genres. A bunch of Ross novels were reprinted in a title called "Vampir Horror Roman" under the subtitle "Barnabas der Vampir." 4 of the first 5 were printed in a romance title. These were random offerings over the course of a couple of decades. Except for the copyright info, none of them mentioned DS. Each cover had a different version of Victioria. In Barnabas Der Vampir, Barnabas was consistently drawn as a grotesque Dracula type vampire. There was one exception. A few years earlier "Barnabas Collins and the Mysterious Ghost" was published with a more romantic Barnabas, slightly reminiscent of Bela Lugosi. If one was reading the Victoria Winters novels, you'd never know they were part of a series based on the covers. You'd have to read the novel to find out it was about a heroine that had appeared years earlier in another installment of the magazine. I have no idea if any of the other Strange Paradise novels every saw print over there.
