Fake Shemp Burke Devlin is starting to suspect that there is something odd about old world gentleman Barnabas Collins. He suspects that Barnabas is not from England as he claims to be. More darkly, he is considering the possibility that Barnabas might be the one who abducted Maggie Evans, The Nicest Girl in Town, and held her prisoner. As it happens, the audience knows that he is correct in both of these suspicions. We also know more- that Barnabas is a vampire.
Burke has hired investigators to probe into Barnabas’ past. Barnabas told him he lived near London with a cousin named Niall Bradford. Burke’s investigators have found that the last time a man of that name lived in London was 130 years previously. Dark Shadows has been going back and forth for months on whether Barnabas lived in the 1830s or in the eighteenth century. Yesterday they seemed to commit themselves to the earlier date, but now we’re back with the 1830s.
Burke asks Maggie’s doctor, addled quack Dave Woodard, to show him all of her medical records. Woodard protests that medical records are confidential. He then tells Burke everything he knows about Maggie’s case.
Burke calls on Maggie. She is back home, apparently well, but suffering from amnesia covering the entire period of her captivity. Unknown to any of the characters we see today, Maggie’s psychiatrist Julia Hoffman is a mad scientist in league with Barnabas, and she has wiped Maggie’s memory clean of any information that might threaten to expose him. Burke talks with Maggie and her boyfriend, hardworking young fisherman Joe, repeating everything Woodard told him a few minutes before.
Maggie and Joe tell Burke that she has had a few visitors since she came home. Maggie blithely mentions that Barnabas was one of those visitors. Burke is startled to hear this, and Maggie repeats that Barnabas dropped in to pay his respects.
During the fourteen weeks when Dark Shadows was driven by undead fire witch Laura Murdoch Collins, Burke saw extensive evidence of supernatural doings. But he lately he has decided that he lives in the kind of world where the show took place in its first few months, where there might be hints of ghosts in the background, but all the action came from flesh and blood humans subject to the usual laws of nature. Since it doesn’t occur to him that a person might have powers like Julia’s, Maggie’s calmness when talking about a visit from Barnabas seems to prove that Barnabas is innocent.

Maggie does say that there is just one memory she has that seems to be connected with her time in captivity. It is a bit of music- “a light, playful tune. A soft, tinkling sound.” She freely admits that it seems unlikely that this would have any connection with such an experience, and speculates that it may have been something she remembered from childhood.
In the great house of Collinwood, well-meaning governess Vicki is listening to the enchanted music box Barnabas gave her. Burke and Vicki are now engaged to be married. He comes to see her, and remarks on the music box. She accuses him of being jealous of Barnabas, and he keeps coming back to the music box. When she opens it for him, he remarks that it makes “a light, playful tune… a soft, tinkling sound.”
The episode ends with Burke listening to the music box and staring off into space. Barnabas gave the music box first to Maggie, then to Vicki, in each case hoping that she would listen to it until its magical quality caused her to believe that she was his lost love Josette. Seeing the look on Burke’s face as he listened, my wife, Mrs Acilius, said “Maybe Burke will start to think that he’s Josette.” Who knows, maybe he and Barnabas could be very happy together.
