My Divinations Have Never Been Wrong

Ye Qing runs a fortune-telling stall on the antique street. The three copper coins passed down in her family have never been wrong, but each reading can only reveal the most important thing that will happen to one person in the next three days. Every time she casts a hexagram, she sacrifices a piece of her own fortune. Then she foretells the death of Wang Jianguo, the hardware store owner, within three days. Following the signs, she uncovers an arson plot, a cut brake line, and someone waiting in a warehouse. Her own fortune has already run dry. Criminal investigator Gu Yan doesn't believe in the supernatural, but he has no choice but to believe her, because not one of her readings has ever been wrong.
