Susan Lancaster

 is a former slaver from Paradise Falls who now lives in Tenpenny Tower. She is one of several bigoted residents you must try to convince to change her mind if you are attempting to help move Roy Phillips' ghouls into Tenpenny Tower.

A love letter in her room reveals that she is having an affair with Edgar Wellington II. Showing this letter to Millicent Wellington will cause her to murder both Edgar and Susan for their treachery.

Dialogue between Susan and Herbert "Daring" Dashwood reveals that she is carrying on an affair with the retired adventurer as well!

She is one of the targets for enslavement that Eulogy put a special bounty on. If she is killed by Millicent Wellington you will still be able to complete Strictly Business by turning in the rest of the targets but you won't get the 250 caps for enslaving her. Also note that the same thing happens if you convinced Tenpenny to allow Roy Phillips et al. to move in - Ms. Lancaster will be residing in Mr. Burke's quarters if you took the mediated approach (she didn't leave the tower.)
