Vampire Barnabas Collins has discovered that he can occasionally see into a parallel universe through a doorway in the long-disused east wing of the great house of Collinwood. He cannot enter that universe or get the attention of its inhabitants, but yesterday a book came flying out of it and landed at his feet. It is titled The Life and Death of Barnabas Collins, and its author is William Hollingshead Loomis.
The Barnabas of the book’s title is our Barnabas’ counterpart in the parallel universe. He never became a vampire, but married his great love Josette, enjoyed prosperity as head of the Collins family, and died a natural death in 1830. It sounds like Parallel Barnabas lived a quiet life of the sort that would make for a dull biography.
Author William Hollingshead Loomis is the counterpart of Willie Loomis, once Barnabas’ sorely bedraggled blood thrall. Willie is back in Barnabas’ house, not as a slave, but as a volunteer in the battles Barnabas and Julia recently waged against the Leviathan People, a race of Elder Gods who sort of wanted to retake the Earth and annihilate humankind, but who could never figure out a way to get started. The Leviathans have been defeated now, and Willie’s fiancée Roxanne expects him to leave with her. But Barnabas and Julia are still bullying Willie into sticking around while they clean up the messes they have made recently. Most notably, yesterday they made him stake Megan Todd, a victim whom Barnabas inadvertently made into a vampire. Today Willie is still talking about how traumatic it was for him to do that.
Parallel William H. Loomis is identified on the back of his book as the author of three best-selling novels that had been made into motion pictures, Pride of Lions, Gold Hatted Lover, and World Beyond the Doors. When Barnabas shows the book to our Willie, he reacts with panic. When he sees in the prefatory material that Parallel William dedicated the book to “the Clio who inspired” him, Willie declares that he doesn’t know anyone by that name. Barnabas contemptuously tells him that Clio was the Muse of History. Willie has never been represented as an especially literate fellow- when Frankenstein’s monster Adam began using standard grammar and diction in August 1968, Willie’s response was to ask “How come he talk so good?” While one suspects that a writer capable of publishing a book under the title Gold Hatted Lover is not exactly Thomas Hardy, Parallel William is clearly more bookish than is our Willie.
Barnabas tells occult expert Timothy Eliot Stokes about the room and takes him there. Stokes is excited by the possibility of examining this direct evidence for the many-worlds hypothesis, but alarmed by Barnabas’ apparent determination to cross over into the parallel universe he has glimpsed. He tells him of the dangers involved, and Barnabas does not want to hear it.

Meanwhile, heiress Carolyn Collins Stoddard is on her honeymoon with a man who once hoped people would call him Jabe. Like all his other hopes, that was summarily dashed, and he answers to Jeb. A leftover from the Leviathan arc, Jabe is plagued by an autonomous shadow that manifests itself to him in the manner of the shadow that plagues Anodos, the protagonist of George MacDonald’s 1858 novel Phantastes. Every time the shadow appears, Jabe insists on fleeing. Today, Carolyn sees the shadow herself, and finally understands why they haven’t been able to spend a whole night in any of the hotels they’ve checked into.
The shadow is not the most impressive special effect on Dark Shadows. In their post about the episode on their blog Dark Shadows Before I Die, John and Christine Scoleri said that the little dance the shadow does ought to be underscored with some Herb Alpert-style music, and they post a video to prove their point.
