Alice Maxwell (first appeared in The Dark Tower I: The Gunslinger)

Alice, nicknamed "Allie", is the proprietor and bartender of the bar, Sheb's, in the town of Tull. While her age is not specifically stated it is assumed that she is in her late forties due to her mentioning pre-menopause. Roland Deschain meets her while in pursuit of the Man in Black in The Gunslinger. She is described as being beautiful, but she has a major scar where her left eye is. In exchange for information about the Man in Black and Nort, Roland agrees to sleep with her. She was given a letter by the Man in Black, telling her to say the word "Nineteen" to Nort in order to learn about death. She eventually succumbs to the temptation knowing that the knowledge will drive her mad. She asks Roland to put her out of her misery, which he does, knowing that Sheb McCurdy (who was holding a knife to her throat during Sylvia Pittston's attack) would probably kill her anyway.

Alice Maxwell is mentioned in the following books:

Cell (Jan 2006)

Alice Maxwell is a twinner for Alice from the Dark Tower. This becomes immediately clear when Alice in Cell is struck in the face with a cinder block; Alice in the Dark Tower has a mysterious scar over her left eye in the same spot.

Clay fell on his knees beside her, calling her name, but he couldn’t hear himself in the sudden roar of Sir Speedy, which was finally getting a trial. Muzzle-flashes strobed the dark, and by their glare he could see blood pouring down the left side of her face—oh God, what face—in a torrent.
