The opening voiceover plays over this image, a type of visual effect we have not seen before at the beginning of an episode:

Barnabas Collins has bitten dimwitted servant Dirk Wilkins, turning Dirk into a vampire like himself. Barnabas has been out all night, searching for Dirk’s hiding place. He hopes to expose Dirk and frame him for his own crimes.
Barnabas comes home to the Old House on the estate of Collinwood to find that Dirk seems to be trying to do the same thing to him. There is a blood-drained corpse in an armchair in his front parlor. It is that of Miss Pansy Faye, Cockney showgirl and Dirk’s first victim.
Barnabas’ distant cousins live in the great house on the estate. One of them, prankster Carl Collins, brought Pansy home with the intention of making her his bride. No sooner does Barnabas discover Pansy’s remains than Carl starts banging on the front door, shouting that he wants to speak with her.
Barnabas hides what’s left of Pansy in a secret chamber behind a bookcase, then lets Carl in. Grisly as the circumstances are, one person lying to another about the presence of a third nearby is a stock situation from farce, and John Karlen and Jonathan Frid play the scene with the particular brand of desperate seriousness that only works in farce. Barnabas persuades Carl to go away and search the grounds of the estate.
That takes a few minutes, starting from what the opening voiceover told us in so many words was “an hour before dawn.” In what remains of that hour, Barnabas takes Pansy’s body to a cemetery and buries her in a shallow grave between tombstones, telling her to “rest in peace.”

Barnabas comes home, and finds Carl, who has in the interval not only gone to the great house, the groundskeeper’s cottage, and a house on the estate which is currently occupied by a school, but has also gone into the village of Collinsport and made inquiries about Pansy. A speedy bunch, the Collinses.
Before Barnabas returned to the house, Carl had heard Pansy’s disembodied voice singing the song she had so memorably performed for Barnabas in yesterday’s episode. He had spoken to Pansy’s voice telling her that his grandmother’s will gave him a house to live in and that she could live there with him. This is puzzling for returning viewers. In #714, it was made perfectly clear that the will did not mention Carl at all. Edith Collins left her entire estate to Carl’s sister Judith, and the only one of the brothers who was mentioned was Quentin, who received no money or negotiable assets of any kind but who was guaranteed the right to stay at Collinwood as long as he pleased. Perhaps they are retconning that away, perhaps Carl is lying to Pansy, or perhaps Carl is losing his grip on reality.
Whether or not we are supposed to doubt Carl’s sanity, Barnabas talks Carl into suspecting that he might have hallucinated Pansy’s voice. Carl leaves, and Barnabas has time to return to his coffin before dawn.
The rest of the episode is taken up with doings at the school Carl had visited. We saw Carl questioning Charity Trask, daughter of the school’s master, the overwhelmingly evil Gregory Trask. The prim Charity was exasperated that Carl kept asking about Pansy after she had already denied having seen her. The scene is an interesting one- Charity and Pansy are such total opposites that it is a shame they never met. It would be amusing to see them juxtaposed.
Charity is engaged to marry Tim Shaw, a teacher at the school. Neither of them is happy about this situation. Tim was in love with Rachel Drummond, another of the teachers, and Charity is Barnabas’ blood thrall. But Gregory blackmailed Tim and bullied Charity into accepting the arrangement.
Charity’s mother, prudish Minerva Trask, does not like Tim or want him as a son-in-law. She urges Charity to set her sights on Carl. Charity says that she would rather marry Barnabas; Minerva says that her instincts are sound, but that she ought not to settle for a cousin of the rich Collinses when one of the brothers is available. Even if they have retconned Carl into owning a house, he is clearly not a rich man, so this reveals that Minerva knows as little about his financial position as she does about the curse under which Barnabas labors.
Charity tries to engage Tim in conversation, and is baffled that he is not willing to talk to her. Indeed, he does not seem like himself at all. Not only is he dismissive with Charity, but when Minerva confronts him he is bold and insolent, a far cry from the broken man we have seen interacting with the Trasks previously. When Charity tells him their engagement is off, he does not express the relief that she and we expect, but puts on a stagey voice we have not heard him use before and marches off to apologize to her mother.
There is a reason for Tim’s behavior. Gregory enlisted warlock Evan Hanley to brainwash Tim so that he would kill Minerva. There is some business with the Queen of Spades, first when Tim mutters the phrase “Queen of Spades,” then when Evan sends him a note on which is scrawled “Queen of Spades,” and lastly when he walks in on Minerva playing solitaire and sees her turn up the Queen of Spades. Many viewers in 1969 would have remembered Richard Condon’s 1959 novel The Manchurian Candidate and its 1962 film version. In Condon’s novel, Raymond Shaw became a robot capable of murder when he saw the Queen of Hearts; in the film, the card was the Queen of Diamonds. Many first time viewers, seeing Tim Shaw’s reaction to the Queen of Spades, would have made the connection and understood why he ends the episode by poisoning Minerva’s tea.

Tim Shaw differs from Raymond Shaw in that he is under a spell for a long while, including the whole time we see him today, and he can talk and act independently while it operates on him. Raymond simply became catatonic when he saw the card and remained that way until he heard a command. He then executed the command and came back to himself once he was finished. Tim’s behavior may suggest a nod to another literary work, Pushkin’s story “The Queen of Spades.” That tale, which Tchaikovsky turned into an opera and which in 1949 was made into a feature film, is about a timid man who inadvertently kills a powerful woman and loses control of himself as a consequence. Like Tim, Captain Herman is coerced into marrying a woman he does not love. Presented with an opportunity to get out of the marriage, he finds himself making extraordinary efforts to go through with it, efforts which bring about his ultimate downfall.
