The Fourth Sacrifice (China Thriller)

Forensic pathologist Margaret Campbell had finally decided to leave Beijing—and the man she loved—and return home to the States. But there’s a new case. Four men have been killed. All of them were from China, and all were victims of what looks like ritual sacrifices.
The U.S. ambassador practically forces Margaret to work once more with Li Yan. As Margaret and Li Yan investigate, they come closer and closer to finding the truth behind the killer’s executions. They also come closer to a killer who will sacrifice anyone to conceal a secret.
