Obsessive. Compulsive. Detective.   An all-new original mystery starring Adrian Monk, the brilliant investigator who always knows when something’s out of place...   Of all the things that make Adrian Monk uneasy, change ranks high on the list. So when Natalie completes her P.I. license—and technically becomes Monk’s boss—it’s not easy for him to accept. Nor can he accept Natalie attending a business seminar at sea without him, even if it means spending a week with her on a cruise ship.   Between choppy waters and obnoxious kids, Monk finds himself in a perfect storm of anxiety. Luckily, Mariah, the cruise director, is always able to smooth things over…until someone pulls the man overboard alarm, the ship drops anchor—and the crew fishes Mariah’s dead body out of the water.   Finding alcohol in Mariah’s system, the ship’s doctor declares her death an accident, but Monk isn’t convinced. He knows that Mariah and the captain were having an affair. Could someone have pushed her overboard?   When the captain hires Monk and Natalie to look into a mysterious rash of vandalism onboard, Monk steers the investigation toward murder…
