Echoes of the Abyss: a Serial Murder Case

A mutilated copper bookmark quietly connects murder cases spanning eleven years. The girl was strangled to death on a rainy night, and the purple mark on her neck looked like an ugly necklace. In the Primus Hotel, two young models were killed with a blunt instrument, and the same copper bookmark was hidden in the corner of the window sill. At the bottom of Ganshan Lake, eleven suitcases contained dismembered remains. Zhang Zefeng, the leader of the serious crime team, chased the murderer for eleven years, from the age of 27 to 38. He thought he was chasing a serial killer, but found that he was just a pawn - the center of a web of evil that had been woven for eighteen years. In the basement of Wendege Bookstore, the walls are covered with photos of victims, with red threads like spider webs. In the center of the photo wall is himself. Below is a line of small letters: "Zhang Zefeng - entered the game in 1992 - the game is still going on." He was never chasing one person. Antique dealer Zheng Mingyi weaves a profit empire through smuggling and loan sharking, and bookstore owner Wu Jiangbo spreads the seeds of psychological manipulation with copper bookmarks. One is in the light and the other is in the dark; one kills and the other covers up. When Zhang Zefeng finally pried open the door of the abyss, what awaited him was an empty glass container. The label read his name - "Last Work". The abyss echoes, justice is never absent. Open this book and walk into the humid rainy night of 2002 with Zhang Zefeng to uncover the truth sealed by the copper bookmark.
