Episode 174 of Dark Shadows, broadcast and set in February 1967, included a scene set in a police station and morgue in Phoenix, Arizona, where we met Lieutenant Costa of the Arizona State Police. Lieutenant Costa was played by John Harkins, who would become a ubiquitous TV presence in the decades to follow.
Harkins returns to the cast today as another law enforcement character. The show is set in 1897, and the action is almost entirely driven by supernatural doings. Harkins’ character, Garth Blackwood, is the late keeper of Dartmoor Prison. He is conjured up from the depths of Hell by sorcerer Count Petofi, who has decided to use him to kill his unreliable servant Aristide. Blackwood was heard but not seen yesterday, in a flashback set near Dartmoor. That flashback broke the record Harkins’ previous appearance had long held for the scene in the series set furthest from Collinsport, Maine.
Blackwood storms into the room where Petofi is recovering from a knife wound Aristide recently inflicted on him. He announces that his prisoner was seen entering the house and threatens Petofi with a heavy chain he carries. Petofi keeps smiling, but points out that he is injured and was unable to stop Aristide leaving. Blackwood exits. The threat suggests that conjuring him up may not have been Petofi’s wisest move. Petofi has such great powers that we have for some time suspected that he himself would have to be the source of his own destruction. Perhaps Blackwood will be the instrument who finishes him off.
At the great house of Collinwood, matriarch Judith Collins Trask tells her lawyer, Evan Hanley, that she is ready to put her husband, the odious Gregory Trask, in his place. She will be changing her will the next day to remove Trask as executor of her estate. Evan, a former co-conspirator of Trask’s in his evil schemes against Judith and others, is reluctant, but can tell there is no point in resisting Judith. He exits, and Trask enters. Judith tells him she will be rewriting her will to pass all of her wealth to worthy causes after she dies, and he is thunderstruck. He exits hastily.
Trask goes to Evan’s house. He tries to talk his onetime partner in crime into stopping Judith’s plan, but Evan says that her resolution is beyond his ability to change. Aristide bursts in. He pleads for help, and reveals that Petofi has conjured up a demon to stalk him. Evan knows Petofi’s power and wants nothing to do with the situation, but Trask does not know what he is dealing with. He promises to help Aristide in return for a favor. Evan leaves the room, and Trask tells Aristide he wants him to commit a murder for him. After he agrees, Evan returns and Trask persuades him to let Aristide stay in his house for an hour.
In Trask’s absence, Blackwood catches up with Aristide. He enters the house, and Aristide flees. He demands Evan let him search the house. Evan’s background as an attorney kicks in, and he declares he will not let Blackwood conduct a search without a warrant. Blackwood’s response is to strangle him with his chain. Evan has been one of the most consistently interesting characters in the 1897 segment; his death is another sign that we will soon be leaving this epoch.
