St.Georges Book Store is a bookstore run by both Gabriel Knight and Grace Nakimura located in New Orleans.
It plays a pivotal role in Gabriel Knight: Sins of the Father but not in the remaing two games as it appears briefly in the begging of Chapter 2 of The Beast Within: A Gabriel Knight Mystery with Grace mainly working behind the counter.
Background
Sins of the Fathers
The Beast Within
Grace Nakimura continued to work at St. George's bookstore while Gabriel finished business in Germany.
The bookshop had become a famous local attraction to fans of Gabriel Knight's bestselling adaptation of the Voodoo Murders. Many copies of the The Voodoo Murders were stocked in the shop.
After he called her for research on his latest case, she chose to leave the bookshop in another's hands, and flew to Germany to assist Gabriel.
