Haunt of Fear #20 (1997)

Gloria was in a cab, running away from her husband Ralph...heading toward the train station and the train that would take her away from this man whom she thought was trying to poison her. Seated on the train, she imagined him at every turn, remembering the $25,000 insurance policies Ralph had taken out on them both, and then remembered that poison bottle he had brought home. A series of events following end when she awakens in her berth on the train, then sees Ralph with an attendant in a white coat, who takes her off to a nice house with bars on it so that Ralph can never get to her again!

A man marries a woman the townsfolk warn him away from because, after her previous five husbands sicken and die, they think she is a vampire. It turns out her child has a rare blood disorder and she has been performing transfusions upon the men as they slept at night. The man knows she isn't a vampire because he is in fact one, and he drains both her and the child's blood.

A chemist strings along a rich admirer of Dr. Jekyll and Mr. Hyde who is willing to pay to have such a personality altering formula recreated. The joke is on the chemist when he ingests the formula he comes up, thinking that it's a placebo, but it actually does work and he loses control of himself and murders his girlfriend.
