Maggie Collins is unnerved because people keep getting murdered in and around the great house of Collinwood. Her husband Quentin was arrested for one of those murders and is the prime suspect in another. He escaped from jail, just in time to be unable to account for his whereabouts during yet another. Maggie goes downstairs and finds old world gentleman Barnabas Collins in the foyer.
Maggie mentions that Alexis Stokes, identical twin sister of Quentin’s late wife Angelique, has suddenly taken ill and is asking her to call her father, evil barfly Tim Stokes. Maggie does not understand what Stokes can do that a doctor can’t, but this has happened before and Stokes was able to fix the problem. Barnabas excuses himself, saying he has urgent business to attend to at the Old House on the other side of the estate. He promises to be back soon.
Maggie hears footsteps outside her bedroom, which she thinks might be Quentin’s. The only friend she has in the great house at the moment is Elizabeth Collins Stoddard, who is under sedation following the murder of her daughter. So she rushes to the Old House to look for Barnabas. He is not in; she finds a strange man in the parlor. She asks him who he is and what he is doing there. He insists that he will ask the questions. He asks what Barnabas has done with “her.” Maggie has no idea what he is talking about. He demands that she look into his eyes; as soon as she does, he realizes she is telling the truth. He orders her to tell Barnabas that he will be back, but refuses to give his name.
Maggie runs back to the great house. She finds Barnabas in the foyer, and gives him a full report. Barnabas urges Maggie to believe in Quentin’s innocence. That is something she can no longer do. She says that she is afraid that Quentin has lost his mind and that he will kill everyone in the house, one by one. We pan out and see Quentin lurking at the top of the stairs, listening.
Maggie has a dream. Quentin comes home smiling, with a spring in his step, after chairing a meeting of the board of directors of Collinsport Enterprises. He takes her in his arms and tells her he’s neglected her long enough. She says she doesn’t feel neglected. He says he is taking six months off work, and that the two of them will be leaving tomorrow for a trip around the world.
Quentin finds a bouquet of flowers. He instantly becomes extremely hostile. He accuses Maggie of receiving the flowers as a gift from her lover. She is baffled and denies his allegations. He strangles her. She wakes up, and finds Quentin standing over her, his hands on either side of her neck.

We’ve never seen Quentin and Maggie as happy as they are in the opening part of her dream, but we have several times seen his mood abruptly flip from cheerful to violent. He is not entirely guilty of any of the murders, but he does sometimes choke people, and was in fact choking the person he is charged with strangling immediately before a witch cast a spell to complete the killing.
Moreover, we have seen a dream very much like this one before. For its first 196 weeks, Dark Shadows was set in another universe. In that continuity, Maggie’s counterpart dreamed of Quentin’s ghost in #682. That dream began with Quentin taking a delighted Maggie in his arms and dancing with her; all of a sudden, for no discernible reason, he interrupted the dance to strangle her.
That Quentin did not confine his strangulations to dreams. He murdered his wife Jenny by strangulation in #748. Wife-strangling is a pastime the two Quentins have in common. This Quentin is suspected of killing Angelique. His defense against that charge is that he could not have driven the pin into the back of her head that killed her, because he was using both hands to choke her at the time. So it would seem that Maggie’s fears are well-founded.
Danny Horn’s post about this episode in his great Dark Shadows Every Day is one of several he wrote as if the show had been set in the current universe from the beginning. It’s hilarious, much recommended.
