Beryl is a editor for Ballantine Books. Not much is known about her, though her and Otho seem to have a negative relationship, as shown by Otho's repeated jabs at her, including one comparing her to the Wicked Witch of the West.
Beryl, Grace, and Bernard were invited to the dinner with Delia, Charles, Otho & Lydia, until they were shockingly surprise by the monster hands. Soon, Lydia thinks, the ghosts, Adam & Barbara, refused to come down, because they might try to scare them away. Thus, Beryl, Grace and Bernard have firmly decided to leave the Deetz's house.
She is a quiet artistic freak. Otho picks on her for this aspect. She is often seen smoking cigarettes and has nervous, twitchy mannerisms. She apperars to be suicidal. Smoking seems to be a relief- at least for a little while.
Previously unsuccessfully attempted committing suicide, possibly on multiple occasions. Again Otho antagonizes her "dreary suicide attempts", saying "You know what they say about people who commit suicide - in the afterlife, they become civil servants".
- It's unknown whether or not Beryl appeared in the animated series.
