Murder at the Lanterne Rouge by Cara Black
Aimée Leduc is happy her long-time business partner René has found a girlfriend. Really, she is. It’s not her fault if she can’t suppress her doubts about the relationship; René is moving way too fast, and Aimée’s instincts tell her Meizi, this supposed love of René’s life, isn’t trustworthy. And her misgivings may not be far off the mark: Meizi disappears during a Chinatown dinner to take a phone call and never comes back to the restaurant. Minutes later, the body of a young man, a science prodigy and volunteer at the nearby Musée, is found shrink-wrapped in an alleyway—with Meizi’s photo in his wallet.
Aimée does not like this scenario one bit, but she can’t figure out how the murder is connected to Meizi’s disappearance. The dead genius was sitting on a discovery that has France’s secret service keeping tabs on him. Now they’re keeping tabs on Aimée. A missing young woman, an illegal immigrant raid in progress, botched affairs of the heart, dirty policemen, the French secret service, cutting-edge science secrets and a murderer on the loose—what has she gotten herself into? And can she get herself—and her friends—back out of it all alive?
