Vampire Angelique wants to take part in an experiment. The experiment is modeled on one in Hammer Studios’ 1967 film Frankenstein Created Woman. A mate will be created for patchwork man Adam by a process that involves draining the “life force” from a person into a female body made up of parts salvaged from several cadavers. Angelique wants to be the “life force” donor.
Angelique knows that when Barnabas Collins donated his “life force” to Adam, he not only survived the process but emerged cured of the vampire curse she had herself placed on him 172 years before, when she was a wicked witch. She is hoping that if she follows his lead, she too will be freed to walk in the daylight.
Angelique has been snacking on an unpleasant man named Peter who prefers to be called Jeff. Peter/ Jeff is working on the experiment as a lab tech. She keeps demanding that he run the experiment with her as the “life force” donor. He keeps explaining that he’s just there to set up the equipment and has no idea how to operate it. The only person qualified to do that is mad scientist Julia Hoffman. Angelique says that no one else must be involved, and gives Peter/ Jeff 24 hours to become an expert on the process.
Meanwhile, Adam visits heiress Carolyn in her bedroom. He describes their relationship in terms that show a far greater maturity than she has seen from him before, and she calls him an “amazing creature.” The word “creature” wounds him. We hear his thoughts in a voiceover monologue, the first time Dark Shadows has used this device in mid-conversation. It is quite unnecessary; Robert Rodan’s face tells us everything we need to know about Adam’s feelings. Carolyn certainly sees that she has hurt Adam, and scrambles to make up for it.
Carolyn gives Adam a bright green sweater, and he bursts into tears. He says that no one has ever given him a gift before. Carolyn does not know about Adam’s origin, and is puzzled by this remark. He tells her no one is as nice as she is, that he wants to be her friend forever and never to hurt her, and rushes out of the room, overwhelmed by his emotions.
The experiment to build a female Frankenstein’s monster began after Adam told Barnabas that if he were not given a mate, he would murder everyone in the great house of Collinwood, including Carolyn. The scene in Carolyn’s room shows that this threat is a hollow one. On Friday, Adam dropped in on suave warlock Nicholas, who put him up to extorting Barnabas and Julia, and told him he loved only Carolyn and was ready to tell Barnabas to forget about the experiment. Nicholas talked him out of that, promising him that he would make it possible for him to have both his mate and Carolyn if only he would do everything he told him to do.
Angelique returns to the lab. Peter/ Jeff isn’t there, but Adam is. She tells Adam that he is breaking his word to Nicholas. Nicholas did not in fact tell Adam to stay away from the lab, but he did give Angelique that command. Adam is skeptical of Angelique, but he has no reason to stay in the lab or to throw her out. So he leaves her there.
Soon Peter/ Jeff is back. He keeps trying to explain to Angelique that he has no idea what he is doing, but she puts herself on the table and insists he start right away. While he throws switches, she moans.
Danny Horn’s post about this episode on Dark Shadows Every Day details the similarities between this scene and the way TV variety shows of the period presented “psychedelic” rock and roll acts such as The Doors. Danny’s commenter “PrisoneroftheNight” (a.k.a. Marc Masse of the intermittently available blog Dark Shadows from the Beginning) points out that The Doors themselves were likely aware of the similarity, as witness a voice that can be heard at the eight second mark of track 11, disc 2, of the CD release of The Doors in Concert calling similar visual effects “Dark Shadows time!”
Danny doesn’t say anything about Lara Parker’s rendering of Angelique’s experience on the table. On Dark Shadows Before I Die, John Scoleri says that Angelique “seemingly enjoys the experiment (because we’ve seen her shriek in pain, and this definitely was not the same),” to which his sister Christine adds that Peter/ Jeff “seemed to be pressing all the right buttons.” When we were watching the episode, Mrs Acilius noticed Peter/ Jeff’s uncomprehending reaction to Angelique’s moans and remarked “Yeah, yeah, we know you’ve never heard a woman make those sounds.”

Two of the four actors in this episode, Nancy Barrett and Roger Davis, are still alive as of this writing. I believe it is the first episode to have a cast that all survived as late as 2021. Robert Rodan died in that year, and Lara Parker in 2023. I don’t know if there are any episodes that still have all-surviving casts. (UPDATED: #751 does!)
