Vault of Horror #21

A knife-throwing act in Hungary was extremely popular. Harry woke up the next day and couldn't rouse Olga, whom he thought was dead. He made burial arrangements, then discovered that Olga was a vampire. Harry decided the act would change and go to the U.S. where Harry became her victim. She continued to feed on him, until one night, at the end of the knife-throwing act, he announced he was going to commit a murder, then threw a wooden stake at his wife's heart before collapsing in death on the stage!
