A while back, Tumblr user “marcycaa” posted this cartoon summarizing the relationships well-meaning governess Vicki has with strange and troubled boy David and flighty heiress Carolyn in the 1966 episodes of Dark Shadows:
Today, Vicki is being held prisoner by the fugitive Matthew, and Carolyn and David are off their leashes. Carolyn telephones dashing action hero Burke to complain that her mother and uncle don’t want her to see him. Burke reacts with disbelief that Carolyn is nattering on about that when Vicki is missing and might be dead.
David is the only one who knows where Matthew is. He is taking food and cigarettes to him. He has begun to suspect that Matthew has Vicki, and is afraid that he will kill her. This fear contends with his fear that he will go to jail for harboring a fugitive. He sneaks off to see Burke to seek reassurance. When Burke asks him what he wants, he says that he wants Burke to tell him that Matthew is innocent and that his hated father, high-born ne’er-do-well Roger, is responsible for everything Matthew has been accused of. When Burke can’t do that, David slips away.
Back in his hiding place in the Old House on the estate of Collinwood, Matthew lies down on a mattress next to the chair to which he has bound Vicki. Before he can get to sleep, he hears voices calling his name. The portrait of Josette Collins glows, eerie music plays, and one of the voices identifies itself as Josette. Vicki can hear none of this and tells Matthew that he must be dreaming. He wants to agree with her, fearing that the only alternative explanation is that he is going mad.
The audience knows that the ghosts are real, but we don’t know whether they mean anyone well. Matthew’s first action upon hearing the voices is to leap up and hold a knife at Vicki’s throat, so it doesn’t seem that they are protecting her. David considers them his friends, but nothing they have done for him has so far led him anywhere but deeper into his constant agony. The last time Vicki was locked up, the ghost of beloved local man Bill Malloy came and told her she would be killed unless she got away soon, but then vanished, leaving her trapped. While it seems likely the voices represent a power that will destroy Matthew, it is by no means clear they will do so before he kills Vicki. For all we can see, they may be about to drive him to do precisely that.
Vicki is our point of view character, but we’ve known Matthew since the second week of the show. As Carolyn tells David today, he’s always been gruff, but has seemed basically well-intentioned. Reclusive matriarch Liz seems to think that Matthew has some sort of cognitive impairment that would make it difficult for him to function in the world at large, and the sheriff’s manner of ordering him about when they have come into contact would suggest that he has the same idea. Matthew’s killing of Bill Malloy and crimes against Vicki have been desperate acts, committed with displays of reluctance and confusion. The idea that Matthew will end as the victim of a malign force that also spells doom for Vicki is therefore logically satisfying and dramatically compelling.
