A vibrant, noir-style book cover in the style of 1920s New York illustrations. The scene features a flapper woman holding a chocolate fairy cake in one hand and a magnifying glass in the other, her expression comically serious. Beside her is a bumbling detective wearing a trench coat and fedora, tripping over a spilled tray of cupcakes. The backdrop is a bustling New York street with 1920s cars, jazz musicians, and art deco buildings. A mysterious shadow of a villain lurks in the background. Bright, bold colors and exaggerated character features create a humorous, playful vibe. Title: "Chocolate Fairy Cake and Murder" in elegant art deco font.
