H.D. Carlton has confirmed that a film adaptation of her controversial BookTok horror-romance novel *Haunting Adeline* is in development. The announcement is significant because the Cat and Mouse Duet has attracted both a highly committed readership and sustained debate over whether its extreme material can be adapted for cinema.

Carlton’s website says a film is “loading”, but no studio, director, cast or release date has been announced. *Haunting Adeline* is the first half of a continuing story with its sequel, *Hunting Adeline*, so any successful adaptation could potentially lead to a second film covering the darker continuation.
