Layover in Dubai

From the acclaimed author of The Cover Wife comes a "fast-paced . fascinating" thriller (The Washington Post) featuring a lethal mix of mobsters, prostitutes, crooked cops, consuls, and corporate players in the mysterious and gleaming city of Dubai. Sam Keller, an auditor at a giant pharmaceutical firm, expected a six-hour layover in Dubai. Then his company's corporate security officer asked him to extend his stay two days to keep an eye on a hard-partying colleague.
Sam agrees, but against his better judgment, he decides to live it up a little, which has disastrous results. First Hatcher is murdered. Then Sam is arrested. Was he set up? Unsure whether he can trust his employer, Sam forms an unlikely alliance detective with Anwar Sharaf, a former pearl diver and gold smuggler.
