Maudette Hornsby was the librarian in the small town of Dual Spires who had a very close, even questionable, relationship with Randy Jackson. When Paula Merral was murdered, she helped Shawn and Gus solve the case through emails. She was herself murdered by Dr. Donna Gooden and Sheriff Andrew Jackson. She is portrayed by Sherilyn Fenn.
In "Dual Spires", Shawn and Gus enter the town of Dual Spires' library to check out Randy Jackson's alibi, as he says he was with Maudette the night of Paula Merral's drowning, which she confirms. While the two check out the library, Gus realizes an earlier email they received was using the Dewey Decimal System.
Later, while Juliet, Shawn and Gus interrogate Randy, he lets slip that he and Maudette used to date. The three rush to the library, but once there find Maudette hanging, dead. It's concluded that she killed Paula, as she was jealous of her relationship with Randy, then was wracked with guilt, and so she killed herself. Shawn and Gus decide to snoop around, and find a wire leading to a computer room, where they discover that it was Maudette who was sending them emails helping them along with the case. Maudette was killed by Dr. Donna Gooden and Sheriff Andrew Jackson, as revealed when the two try to kill Shawn, Gus, Robert Barker and Father Westley.
Maudette frequently riffs off Sherilyn Fenn's role on Twin Peaks as Audrey Horne, from her name onward.
