Our view
“Moonflower Murders” hides one whodunit inside another, ingeniously and with plenty of twists. Anthony Horowitz sends Susan Ryeland after a hotel employee who has disappeared, and tells it through a story set inside the story. Some readers find that structure confusing and drawn out. At over six hundred pages, it is the second Susan Ryeland mystery and a puzzle built in layers.
