In the great house of Collinwood, matriarch Liz lies unconscious on a sofa, stricken with a mysterious ailment. Well-meaning governess Vicki cannot find Liz’ pulse or heartbeat, and fears she may have died.
Vicki telephones the family doctor. Her boyfriend, an unpleasant man named Peter who prefers to be called Jeff, asks why she doesn’t call for permanent houseguest Julia Hoffman, MD. She explains Julia is at the Old House on the estate, home to old world gentleman Barnabas, and that there is no telephone there.
We cut to a bedroom where Barnabas and Julia are devising a plot to murder a woman named Eve. Since Vicki had said they were at the Old House, even longtime viewers will be unlikely to recognize this as Julia’s seldom-seen bedroom at the great house. She had been staying with Barnabas for a while; we might wonder if it is his bedroom, which we have never seen, or if she has a room of her own at his house now.
Julia has a hypodermic needle and plans to fill it with a concoction that will induce a heart attack and immediately dissolve in the bloodstream. This was the weapon Julia prepared for the first murder she and Barnabas committed together, when they killed Dr Dave Woodard in #341. Julia was all broken up about that, but then she and Dave were old med school classmates. Eve is just an undead abomination they whipped up in the laboratory, not a colleague, so Julia is relaxed and smiling this time. Her smile vanishes, though, when the topic turns to Barnabas’ intention to let himself into the house where Eve is staying. It is the home of suave warlock Nicholas, a formidable adversary, and Julia fears he may be walking into a trap.
Julia and Barnabas go downstairs and find Vicki and Peter/ Jeff with the unconscious Liz. Julia examines Liz and pronounces her dead. Seconds later, Liz sits up and starts talking. This is the second death pronouncement Julia has made in the last few days; in #592, which in dramatic time is supposed to have been last night, she declared Liz’ daughter Carolyn dead. Carolyn showed up alive and well a little later, so you might wonder if Julia will wait for an EEG reading next time.
Julia has a nightmare in which it turns out she was right and Barnabas did fall into a trap at Nicholas’ house. They do all the dialogue in recorded voiceover, a device they’ve been exploring lately, and shoot the whole thing through a gauzy filter. The recorded voiceover is OK, but the filter is pretty bad- it just looks like they needed to clean the lens. They even shoot the closing credits through the same greasy smudges. The result is far from satisfactory.

I left a comment on Danny Horn’s post about this episode on Dark Shadows Every Day. I note that Roger Davis, the actor who plays Peter/ Jeff, was in his usual form in this one:
When Barnabas sees Jeff kissing Vicki, he reacts with alarm and rushes out. We were alarmed too- Alexandra Moltke looked excruciatingly uncomfortable during the the first kiss. We almost expected her to call out to Barnabas to rescue her from the second.
Also, at the beginning of the episode Jeff is supposed to feel for Elizabeth’s heartbeat, so Roger Davis helps himself to a handful of Joan Bennett’s left breast. Classy guy…
