Obsessive. Compulsive. Detective. An all-new original mystery starring Adrian Monk, the brilliant investigator who always knows when something’s out of place.... No one likes to come home to a mess—least of all Monk and Natalie. But when they return briefly to San Francisco from an extended stay working as cops in New Jersey, Natalie discovers somebody has been sleeping in her bed. But this Goldilocks is not asleep. She’s dead. If that’s not bad enough, investigators find marked money from a Federal sting operation stuffed under Natalie’s mattress. Now her life is a real mess and she needs Monk’s help to clean it up. But Monk has problems of his own. His brother Ambrose is desperate to find Yuki, his missing lover, but his agoraphobia prevents him from leaving the house. Ambrose needs a man on the outside—and that man is Monk, who is torn, because he’s glad to see her go. As the two investigations begin, and the body count rises, it quickly becomes clear to Monk that Yuki has a dangerous past…and that they are pursuing a ruthless, cold-blooded killer that nobody would ever want to mess with…

Monk's house is being fumigated, and he has nowhere to go. Fortunately, his assistant Natalie and her daughter are kind enough to welcome him into their home. Unfortunately, their home is not quite up to Monk's standards of cleanliness and order. But while Monk attempts to arrange his surroundings just so, something else needs to be put straight. The death of a dog at the local firehouse-on the same night as a fatal house fire-has led Monk into a puzzling mystery. And much to his horror, he's going to have to dig through a lot of dirt to find the answer.

Ever since a 1962 unsolved train robbery made it famous, people have flocked to the town of Trouble in California's gold country, searching for the booty that train robbers supposedly dumped off the Golden Rail Express in a botched heist. When the town's museum's watchman is murdered, Adrian Monk and his assistant, Natalie, are sent to investigate. But if Monk isn't careful, he'll learn that the town of Trouble can live up to its name.

Some people think Hawaii is paradise. But Monk knows that danger—like dirt—lurks everywhere. Look at Helen Gruber, the rich tourist who took a fatal blow from a coconut. The police say it fell from a tree, but Monk suspects otherwise. His assistant, Natalie, isn’t exactly thrilled about Monk’s latest investigation. It was bad enough that Monk followed her on vacation, and now it looks as though the vacation is over.... Smooth-talking TV psychic Dylan Swift is on the island and claims to have a message from beyond—from Helen Gruber. Monk has his doubts about Swift’s credibility. But finding the killer and proving Swift a fraud—all while coping with geckos and the horror of unsynchronized ceiling fans—may prove a tough coconut to crack....
