Vampire Barnabas Collins and mad scientist Julia Hoffman are trying to prevent a disaster that is fated to destroy the great house of Collinwood and everyone in it before the year 1970 is out. They have a handful of cryptic phrases that clue them in to events that will precede this disaster. One of the phrases is “The night Rose Cottage was destroyed.” They have no idea what Rose Cottage is, and have been unable to find anyone who does.
Julia finds heiress Carolyn Stoddard Hawkes leaving the great house. Carolyn says nonchalantly that there is something she has to do at Rose Cottage. Julia gets Carolyn to say that going to Rose Cottage involves leaving the grounds of Collinwood through the front gate. She asks her to mail a letter for her on her way. She agrees, and waits outside while Julia goes back into the house to get the letter.
Julia rushes to a bedroom where Barnabas is sitting with governess Maggie Evans, who is the victim of a vampire other than himself. Julia fabricates a letter while repeating to Barnabas what Carolyn said. Julia takes over the vigil, and Barnabas gives Carolyn the phony letter. He then follows her to a deserted mansion in the area.
Barnabas barges in on Carolyn in a room in Rose Cottage. He ignores her indignation at his following her and presses her with questions:
CAROLYN: Barnabas!
BARNABAS: So this is Rose Cottage.
CAROLYN: You followed me here!
BARNABAS: Carolyn, who is your friend? Who were you talking to just before I came in?
CAROLYN: That, that really is no concern of yours, now is it?
BARNABAS: Carolyn, you must tell us everything you know about this place, who lived here and who it was you were trying to find.
CAROLYN: Why are you and Dr. Hoffman so interested in this place?
BARNABAS: We’ve told you before one of the events that’s to happen before the disaster at Collinwood is the destruction of Rose Cottage.
CAROLYN: Rose Cottage… [laughs] Now, that’s a strange name for a place like this, isn’t it?
BARNABAS: I know now why it was so difficult to find. How did it get such a name?
CAROLYN: Oh, it happened a very long time ago, when Carrie was very small.
BARNABAS: Carrie lived here?
CAROLYN: Are you going to be quiet and let me tell you?
BARNABAS: I’m sorry, go on.
CAROLYN: Carrie, Carrie always dreamed of having a doll’s house which she would call Rose Cottage. So for her birthday I asked Quentin to build her one. Quentin was so good with his hands you know, and so terribly inventive. He actually built a replica of this house, and I gave it to Carrie for her birthday. [laughs] I told her she would have to find another name for it, but she said no, it would always be Rose Cottage to her. So she kept calling it that, and before very long people called the mansion itself Rose Cottage.
BARNABAS: When was all this, Carolyn?
CAROLYN: I’m not going to answer any more of your questions! You were very rude to follow me here, very rude indeed!
Carrie died in 1841. Her ghost has taken possession of teenager Hallie Stokes. The ghost of Carrie’s friend Tad has taken possession of David Collins. Tad and Carrie, in personis David and Hallie, are currently at Windcliff, a psychiatric facility Julia controls. Before they were taken there, Carrie and Tad did some mumbo-jumbo and restored their late governess Daphne Harridge to life. Daphne then led Tad and Carrie in an unsuccessful attempt to do the same for another ghost, erstwhile pirate captain Gerard Stiles. Carolyn is possessed by the spirit of a certain Leticia Faye, though unlike Hallie and David her own personality still exists within her body and from time to time asserts itself.
We have seen the dollhouse of which Carolyn/ Leticia speaks many times, and we know that it is in some supernatural sense identical with the full-scale mansion. The episode opened with a reprise of Friday’s cliffhanger, in which Gerard used the dollhouse to trap Daphne in the mansion and to set fire to it. Carolyn/ Leticia interrupted Gerard and saved Daphne.
Barnabas returns to the great house and tells Julia that he now knows where Rose Cottage is. He says that he saw Carolyn there. She asks if he got any information out of Carolyn. He says that he did not. He does not mention the business about Carrie and the dollhouse, which is just bizarre. He and Julia know about a mysterious playroom full of toys appropriate to small children that intermittently appears in a space in a little used part of the great house otherwise occupied by a linen closet. They know that all four ghosts are associated with this playroom. You would think he would therefore realize that a story about a toy of Carrie’s would be relevant to their concerns, but apparently the connection escaped him.
In the last scene, Julia is in Maggie’s room when she is suddenly seized by a fit of sleepiness. A dark figure in a cloak and a slouch hat appears inside the window. Maggie gets up and goes to the figure, who is no taller than she is.

I don’t know if the above makes it clear, but this episode is a sharp step up from last week’s offerings. It is tightly paced, clearly developed, and forcefully acted, a bright spot in a storyline that has been desperately dreary so far.
