This page is for the book character. For the video game character, see Deirdre Shannon (video game character).

Deirdre Shannon, alternatively Deidre Shannon, is a recurring character in the Nancy Drew: Girl Detective series.


Deirdre lives in Nancy Drew's hometown of River Heights and has been Nancy's sworn enemy since they were in 1st-grade. She's slender with short, dark hair and pale skin. Like Nancy's father, Carson Drew, Deirdre's father works as an attorney, and the Shannons are a wealthy family like the Drews are.

She used to go by "Dee Dee" as a little kid, but hates the nickname now, and snaps at anyone who calls her that.


She's considered a rich, spoiled, self-centered snob who dislikes Nancy and her two best friends, Bess Marvin and George Fayne, but is also shown to have a crush on Nancy's boyfriend, Ned Nickerson, who she often flirts with.

Deirdre considers Nancy her rival, and has a strong desire to prove that she's better sleuth than Nancy is, despite the fact that neither of them are professional detectives. Deidre's parents are often pressuring her into being more like Nancy, and Deirdre will sarcastically say, "Well, if it isn't the famous Nancy Drew!" whenever she sees Nancy, hinting at strong jealousy towards Nancy's popularity.
