Book excerpt: One night in Monaco, my best friend, Maxence, disappeared.I have no idea what Maxence was doing in Monaco that night. Yeah, he loves the Monte Carlo casino-the venue of British spy movies, billionaires, Russian mafia, and roulette.But too many people in Monaco think he might be a danger to them.He never should have been there.But he was.So was Simone. She's trouble from our past at boarding school. Her husband is a good friend of some of the people who would be happier if Maxence wasn't around anymore.They tell me Maxence was here in the casino, and then a few minutes later, he was gone.Like he dropped off the face of the Earth.Or like he was dropped off a cliff and into the blue Mediterranean Sea, which was just a few feet from where he was standing.Arthur and I are here to find Maxence, no matter what it takes.But we're afraid we'll end up finding his body.
