Thunder rumbles. The lights go out at Collinwood. Alone in the drawing room, Vicki lights a candle. The doors swing open, and a darkened figure stands in shadow. Vicki calls to the figure. It does not respond. The lights come back on. The figure has vanished. Roger happens by; he is the only other person in the house, but he is too tall to have been the figure.
This is the second occurrence in the series that is either a supernatural manifestation or an elaborate Scooby Doo-esque prank on Vicki. The first time, in episode 14, happened when David had taken the bleeder valve from the braking system on his father’s car, an event that would have dire consequences. We can assume that this second occurrence is telling us that we are about to see events that will stir up the supernatural back-world of Josette, the Widows, and heaven knows who else.
David had planted the bleeder valve in Burke’s room, trying to frame the family’s enemy for his own crime. When he spends a few minutes with Burke and takes a liking to him, he tries to retrieve the valve, not knowing that Burke has already found it and that he is carrying it in his pocket. In Burke’s car on the way to Collinwood, he pleads with Burke to go back to the hotel. He can’t give an explanation for his plea, and Burke refuses to turn back without one.
Vicki tells Roger that she had found the bleeder valve in David’s room, and Roger quickly accepts that his son had tried to murder him. When Burke brings David home, Roger takes David into the drawing room and demands he confess to his crime. Burke refuses to leave the house. Roger calls Vicki into the room; Burke insists on joining them. David calls Vicki a liar, Roger continues to browbeat him. We see a reaction shot of Burke in profile, standing in the doorway, watching the scene intently. Roger mentions the bleeder valve; Burke steps forward, and with a flourish produces the valve from his pocket. David’s face crumbles into absolute dejection.
Has Burke really betrayed David? Or is he playing some other game? We have to tune in next time to find out.
So, we begin with an indication that what follows will stir up the back-worlds, and then see an episode about the relationship between Burke and David. Roger describes Burke and David as “the two people I dislike the most.” Something Burke and David have in common, something that Roger cannot forgive, is going to bring the ghosts out of the woodwork and into the foreground.
