Summary: This issue opens with Jack waking from a nightmare to a noise from outside his home. He sneaks around the intuder and attacks. He is thus introduced to Buck Cowan, who will become his best friend later on. Buck, working on an occult story, is here to give Jack information of his dead father and the dealings of his current step-father Phillip. It seems that since Jack's mother's death in MSp #2, Phillip had taken the castle that Jack had inherited and "..sold it to some dude named Blackgar, and he had it shipped stone by stone from Europe-- set the whole thing up on an island off the Monterey coast."
Jack and buck plan on getting into the castle, to retrive the Darkhold, said to be there. Next morning Buck shows up at Jack's father's house in sailor costume and lays out a story about having to move master Phillips' boat at the docks. Phillip decides to go with him, so Buck distracts him while Jack runs to the boat and casts off for the island, but before he can get there a storm comes upon him and his boat is boarded and captured by what looks to be a modern pirate, who sinks the boat. Jack is taken to the island, there to meet Mr. Blackgar and his daughter Marlene, and is introduced formally to the mysterious Garth, his captor. Mr. Blackgar runs an institution on the island, and it is near there that Jack is taken under guard. Marlene sees to him, and Jack tells her how he is searching for the Darkhold. She is afraid, but decides to help Jack find it, possibly going with Jack away from here. They are interrupted by Miles, Mr. Blackgar, who needs Marlene to assist him in an operation on one of their "inmates". Jack follows to what looks like Dr. Frankenstein's lab. Jack finds the book, but the full moon hits him and he changes to the werewolf! He leaves the book and trashes some of the now-empty lab. He goes lower into the castle, following Garth, who the wolf remembers as an enemy. Jack finds the "inmates" of the "institution", horrible misshapen creatures that Jack then frees. Garth shoots at them until the werewolf jumps him like a rabbit, beats him down like a weiner dog and leaves him to his fate at the hands of the lab rats.
Jack wanders the castle into the welcome darkess, where Marlene finds him. Unafraid, she leads him back upstairs, where he finds Miles again. Jack attacks and the fight is on! Miles keeps himself in great shape and slaps the werewolf around like red-headed step-child until Jack gets a good hold and tosses him out the window to his doom. Marlene waits for him then. It was her plan to kill her father, as she was to be the next "monstrosity" of her father's creation. The werewolf isn't too sure about any of this. She touches Jack and her goes off on her, striking her. She retaliates by looking upon him with her uncovered, unshaded eyes, whilch We had not seen all issue. She is a mutant, a girl with the Gorgon's gaze. Jack is turned to stone instantly.
