Set against the glamorous backdrop of a lavish costume ball, the story begins with an atmosphere of celebration and mystery, where masks and disguises conceal more than playful identities.

As the investigation unfolds, clues emerge through subtle conversations, unexpected encounters, and the careful observation of human behavior. The narrative keeps readers guessing, skillfully balancing fair-play mystery with mounting psychological pressure. Each character, masked both literally and figuratively, becomes a potential suspect, and the ballroom itself transforms into a confined stage for fear, secrets, and revelation.This illustrated edition enhances the novel’s atmospheric quality, bringing visual depth to Farjeon’s vivid descriptions and sharp plotting. Fancy Dress Ball stands as a compelling example of early twentieth-century crime fiction, appealing to readers who enjoy refined mysteries with a strong sense of place and character. Combining classic detective elements with an almost theatrical setting, the novel remains an engaging and stylish read for fans of traditional whodunits.
