The Phantom and Barnabas Collins (September 1969)

Maggie Evans visits the Collins family graveyard and is transported back in time to the year 1880. There she awakes, an amnesia victim, at a Collinwood she barely recognizes. All that seems familiar are the house itself and the family's guest, Barnabas Collins.

Slowly, Maggie learns she is trapped in a nightmare. She has fallen into the hands of Dr. Giles Collins, whose mysterious experiments with human blood have already taken several lives. Now she is slated to be his next victim.

Though Maggie is warned by the others that he is a vampire, she turns to Barnabas for help. But Barnabas, too, is in danger from the evil doctor. Will he live long enough to save her?

Convinced the children are possessed by a mysterious, supernatural power, and frightened for her life, Maggie turns for help to Barnabas Collins.

Will his powers be strong enough to overcome the evil forces that captured the minds of the children before they—and Barnabas—are completely at the mercy of the devil himself?
