Dark Shadows - Season 6 - Eps 173: DS-635
Barnabas returns to the Old House and tells Julia that Nicholas is dead. Julia hugs Barnabas in relief. Meanwhile, Adam, still determined to find a life force for his mate, breaks into Collinwood and knocks Vicki unconscious. Carolyn tries to stop him, but he knocks her unconscious as well. He carries Vickie out of the house and takes her to the Old House. Locking her in the basement, he straps her to the table, connecting her to the skeleton that was Eve. Barnabas and Julia try to break into the basement, but the door is locked. Adam turns on the equipment, and begins draining Vicki's life force from her. Barnabas manages to break into the basement and confronts Adam with a rifle. Adam laughs tauntingly and tells Barnabas that he can't kill him, or else he'll revert back to what he was. Barnabas hesitates, and Adam goes back to controlling the machinery. Barnabas shoots Adam in the back.

Synopsis
Dark Shadows is an American gothic soap opera that originally aired weekdays on the ABC television network, from June 27, 1966, to April 2, 1971. The show was created by Dan Curtis. The story bible, which was written by Art Wallace, does not mention any supernatural elements. It was unprecedented in daytime television when ghosts were introduced about six months after it began. The series became hugely popular when vampire Barnabas Collins appeared a year into its run. Dark Shadows also featured werewolves, zombies, man-made monsters, witches, warlocks, time travel, and a parallel universe. A small company of actors each played many roles; indeed, as actors came and went, some characters were played by more than one actor. Major writers besides Art Wallace included Malcolm Marmorstein, Sam Hall, Gordon Russell, and Violet Welles.
