Since #1021, Barnabas Collins has been trying to figure out what links mild-mannered scientist Cyrus Longworth with a strange and violent man known as John Yaeger. Yesterday, Cyrus telephoned Barnabas and told him that Yaeger was holding Maggie Collins prisoner in an old farmhouse. Today, Barnabas finds Yaeger choking Maggie in the basement of that farmhouse.
Barnabas orders Yaeger to unhand Maggie, saying that he will kill him if he does not. Maggie gives an ecstatic look, then Yaeger flings her to the floor. He and Barnabas start fighting. Yaeger’s weapon of choice is a heavy cane that conceals a bayonet. The other day, Barnabas was looking at his own heavy cane and thinking about what an effective weapon it is, setting us up to expect a cane fight between him and Yaeger. Returning viewers will therefore be puzzled that Barnabas doesn’t even have his cane. Barnabas’ cane is one of his signature gimmicks, so maybe the makers of the show didn’t want to risk damaging it.
Yaeger exposes the bayonet in his cane and stabs Barnabas with it. Barnabas pulls it out of his chest and keeps coming. Yaeger asks “What kind of creature are you?,” to which Barnabas replies that he will never know. Barnabas strangles Yaeger to death. Barnabas’ threatening statements to Yaeger combine with the fact that he keeps choking him well after he becomes unconscious to leave us no label for this act other than willful murder.
Maggie gets up and goes into the room where Barnabas has just finished killing Yaeger. As she does so, there is a bad goof in the production, as a gap in the panel behind her exposes another set, the one representing the foyer of the great house of Collinwood. Watching Dark Shadows is an education in how resilient an audience’s suspension of disbelief can be, but the idea that the farmhouse is very far from the great house is so important to the suspense that this one really does undercut the rest of the episode.

Maggie and Barnabas watch in amazement as the dead Yaeger transforms into Cyrus. Once they have absorbed the implication that Yaeger was just Cyrus in disguise, Barnabas takes Maggie home to the great house.
Maggie is walking when Barnabas gets her in the front door, but she is unconscious by the time he puts her on the couch in the drawing room. Housekeeper Julia Hoffman and Carolyn Stoddard Loomis, a cousin of Maggie’s husband Quentin, are astounded to see them, and have many questions. Barnabas confirms that Yaeger was holding Maggie prisoner and that he is now dead, then orders Hoffman to bring a blanket for her mistress.
Quentin comes home. Barnabas tells him they must go to the farmhouse at once. There, they see Cyrus’ body. Thinking of what Barnabas and Maggie saw, Quentin realizes that the experiment Cyrus had been so secretive about must have been the creation of a Jekyll and Hyde formula. He decides that they should tell the police everything, in spite of the damage it will do to Cyrus’ posthumous reputation and the risk that Barnabas might be inconvenienced in some way for having murdered him.
Quentin has only known Barnabas for a few weeks, and has been wary of him. He has been especially impatient over the last several days with Barnabas’ insistence that Maggie was in danger when he was under the impression that she had merely left the house. This scene shows us Quentin’s remorse at having disbelieved Barnabas, and marks the beginning of a friendship between the two.
Back in the great house, Hoffman is in a brightly lit, richly decorated room, making a telephone call. She is telling the person on the other end of the line that she has learned a crucial secret about Barnabas, and that this secret might be just what they have been looking for. She promises to tell the other person what the secret is once they can talk face to face. Returning viewers know that Hoffman is talking to Quentin’s undead first wife, Angelique, who has been staying in the great house in the guise of her identical twin sister Alexis. The two of them have been scheming to split Maggie and Quentin up so that Angelique can remarry Quentin and resume her place as the mistress of Collinwood. They were in league with Cyrus/ Yaeger, and are afraid that their enemy Barnabas may have picked up some information from him that he can use against them.
Later, Hoffman is on her way back to the same room, perhaps to place another call to Angelique. She finds she cannot pass through the doorway. A phenomenon is occurring that others have seen before. Hoffman sees, not the room that is in that space as she knows it, but dark, bare walls. There are two people there, whom she can see and hear though they are not aware of her. They appear to be herself and Quentin, and they are talking about Barnabas. The man says that Barnabas will be doomed if the “people in that other time” find out that he is a vampire.
Regular viewers know that the man and woman are Julia Hoffman and Quentin Collins, but not the Hoffman and Quentin we have come to know over the last eleven weeks. They are part of another universe altogether. For its first 196 weeks, Dark Shadows was set in that universe, and most of the current characters are counterparts of characters we met there. Barnabas crossed over from that continuity to this one in the futile hope that by doing so he would escape the vampire curse and become human again. Hoffman’s counterpart in the original continuity, Julia Hoffman MD, is as devoted to the undead Barnabas as Hoffman herself is to the undead Angelique. Quentin’s is best friend and confidant to Barnabas and Julia, and is neither the master of Collinwood nor married to his world’s version of Maggie, who is the governess at Collinwood.
Earlier this week, Barnabas popped back to his own reality for a few minutes and talked with Julia. It is his fault that she and Quentin are talking about his vampirism where Hoffman can hear them. He knew that the room as it is in the original universe occasionally becomes perceptible to people in the current universe, since he and Quentin themselves saw it when Julia was standing there talking about him. He just did not think to mention that fact to her.
In the foyer, Barnabas tells Carolyn to stay with Maggie. Carolyn points out that her husband Will Loomis is going to be away until mid-morning, so Barnabas will be alone in their house for several hours. He says he will be all right. While she eavesdrops on this conversation from the drawing room, Hoffman uses the mirror in Carolyn’s compact to confirm that Barnabas does not cast a reflection.
This is precisely the same method Julia used in the original continuity, in #288, to make sure Barnabas was a vampire. The feature film House of Dark Shadows wrapped principal photography several weeks ago; Julia does the same thing there. It is somewhat undercut for returning viewers, not so much by the many times Jonathan Frid’s reflection is inadvertently captured in the many mirrors that decorate the sets in this “mirror universe,” but by the deliberate choice the show made in #1033 to show us an inverted reflection of Barnabas in a magnifying glass in Cyrus’ laboratory. Also, longtime viewers will remember a period in 1968 when Angelique’s counterpart in the main continuity was a vampire. They went out of their way to show us her reflection several times. They never explained what point that was supposed to be making, but it was obviously intentional. If we were confused then, we will be confused again this week.
Julia learned earlier this week that Barnabas keeps an empty coffin behind a secret panel in Carolyn and Will’s house. So she knows where to go this morning. She opens the coffin, places a stake on Barnabas’ chest, and raises a hammer to drive it through his heart. Roll credits!
This cliffhanger leaves us wondering who will interrupt Hoffman and save Barnabas in the first scene of act one on Monday. Carolyn and Will are Barnabas’ victims and are in charge of protecting him, so it would be logical for one or both of them to come home earlier than expected. That would be an anticlimax, but the characters are on the show so rarely and the actors are so dynamic that it would have its compensations. Barnabas has a third victim, Buffie Harrington. We haven’t seen Buffie since #1023 or heard her name since #1028, but regular viewers were reminded of her yesterday when Barnabas mentioned an incident he could have learned about only from her. So it would make sense for her to show up, and it would certainly be nice to see her again.
There are also a few long-shot possibilities. The show spent much of 1969 explaining how Barnabas and Quentin became friends; today Quentin’s counterpart accepts Barnabas as a friend. Perhaps this continuity’s Quentin will somehow save Barnabas. Also, Barnabas’ brief visit home suggests that the barrier between the universes is getting leakier, so we can’t discount the possibility that the original Quentin, the original Julia, or perhaps Will’s counterpart or another character from the old days may happen by.
