Greta

Greta is a very friendly ghoul who works at Carol's Place in Underworld. Every once in a while she'll head outside to the Museum of History lobby area to smoke a cigarette. You can loot her body for 10mm bullets, a 10mm pistol, Carol's Place Supply Key, and a Dirty Pre-War Spring Outfit.

Unmarked quest: Hired Help
In exchange for Charon's contract, Ahzrukhal wants Greta dead. You can choose to fulfill his wish or simply buy the contract from him.
