Cheng Yunqi is a Chinese author of suspense and mystery fiction, though public information about the writer remains limited, with details such as biography, nationality, and dates of birth and death not clearly recorded. Two of the author's works are included in the collection: The Strange Case at Cliff Villa and The Secret of the Seven Dials. Both are classified as suspense and mystery, indicating a focus on puzzle-driven detective fiction. Judging from the imagery in the titles, the works tend to unfold around enclosed settings or intricate clues, carrying the plotting pleasures of classic mystery novels. Although available material is not yet sufficient to trace a complete creative trajectory, Cheng Yunqi has left a mark on Chinese mystery readers with these two works, which may serve as a reference for those interested in domestic suspense writing. More public information is awaited to present a fuller picture of the author's writing.
