Deborah Vane is the leader of the Puritan girls who play with witchcraft. She wants to marry Reverend Johnson. The girls are all from well-connected and respectable families, but they are catty and petty. They torment Mary on the ship to America, and in Beulah, they accuse Mary of witchcraft, offering to keep her secret if she bespells their chosen husbands. Since Mary refuses, the girls dabble themselves, practicing spells in the forest and one another's homes and barns. When they are caught, they feign madness and possession, ultimately accusing Mary of sending her spirit against them.
