In the sequel to Magpie Murders, titled Moonflower Murders, Susan Ryeland, portrayed by Lesley Manville, has relocated to Crete to run a hotel with her boyfriend Andreas, but struggles with the challenges of hospitality life. The storyline intertwines her current investigation into the disappearance of Cecily Treherne with a murder that took place eight years ago at a hotel in England, which was the basis for a novel by the late Alan Conway. The Trehernes believe that Cecily, who disappeared after claiming to have found evidence in Conway's book that could exonerate a wrongfully convicted man, is connected to this old case. As Susan grapples with hotel issues and her dissatisfaction with her new life, she is drawn back into detective work to uncover the truth behind Cecily's disappearance. The narrative cleverly juxtaposes Susan's real-world investigation with a fictional mystery from Conway's work, highlighting the dual storytelling that characterizes Horowitz's creations. This season promises to deepen the character dynamics as Susan confronts both personal and professional challenges.
