A widow who is hell-bent on taking revenge upon those who killed her husband. Relentless and afraid of nothing and no one. The wrong woman to cross, but very loyal to those she loves.
—Rockstar Games' description of Sadie.
A widow seeking vengeance for the death of her husband, Sadie Adler is an outlaw affiliated with the 范特林幫 by 1899; her dialogue with fellow member 亞瑟‧摩根 implies there is little trust between her and the rest of the gang, but she does seem to get along with Morgan.
