Madame Tracy is Mr. Shadwell’s next-door neighbor. She’s a middle-aged woman who makes a living by hosting séances. In Mr. Shadwell’s understanding, she’s also a sex worker—he often refers to her as the Whore of Babylon, which Madame Tracy allows, as it gives her free publicity. A kind, generous, and practical woman, Madame Tracy keeps an eye on Shadwell and even fixes him Sunday dinner every week. She also takes a no-nonsense approach to her séances (during which she never actually communicates with the dead, as it’s all an act). She understands that most people aren’t looking for an experience that’s frightening or seems too real—instead, what people really want is just to know that their friends and loved ones are okay on the other side. As such, Madame Tracy has her act carefully planned to give people just the right amount of intrigue and spiritual connection to their deceased loved ones. Aziraphale briefly possesses Madame Tracy’s body after Shadwell manages to exorcise him, which causes Madame Tracy to speak in two different voices. Following Armageddon, Madame Tracy and Shadwell become a couple and decide to move to the countryside together.
