    A woman drew her long black hair out tight
    And fiddled whisper music on those strings
    And bats with baby faces in the violet light
    Whistled, and beat their wings
    And crawled head downward down a blackened wall....

    If I’ve killed one man, I’ve killed two—
    The vampire who said he was you
    And drank my blood for a year,
    Seven years, if you want to know.
    Sylvia Plath (1932–1963)
