Valerie Solanis

 was a human writer. She was part of Andy Warhol's crowd at the Factory. She was a friend of Iris Wildthyme.

Valerie, who was a feminist, wrote a book called The Scum Manifesto. She wrote a play that she hoped Warhol would produce, but she had fallen out of favor with him. She was so angry with him that she wanted to kill him. She apparently went to the Factory and shot him, merely wounding him because of the interference of the Eighth Doctor. However, she was actually in Paris at the time of the shooting, promoting her book. It had been a clone that shot Warhol. (PROSE: Femme Fatale)
