The Shanghai Moon — S.J. Rozan

In Shanghai, excavation has unearthed a cache of jewelry dating from World War II, when the city was a safe haven for thousands of Jews fleeing Hitler's Europe. The jewelry was stolen soon after it was found by a Chinese official now believed to be in New York City. P.I. Lydia Chin is brought in by her old mentor, Joel Pilarsky, to recover the missing jewels.

But there is more to the story than they've been told: The Shanghai Moon, one of the world's most sought-after missing gems, reputed to be worth millions, is believed to have been part of the same stash. Before Lydia can act, there's a murder, Lydia's fired, and her estranged partner, Bill Smith, finally reappears. Now Lydia and Bill must unravel the truth about the Shanghai Moon -- and the events that surrounded its disappearance sixty years ago during the chaos of war and revolution -- if they are to find the killer and uncover the long-buried truth.
