Mr. Monk in Trouble is the ninth novel based on the television series Monk. It was written by Lee Goldberg, and was published by Signet Books on December 1, 2009. Like the other Monk novels, the story is narrated by Natalie Teeger, the assistant of the title character, Adrian Monk.
Adrian Monk and Natalie Teeger arrive in Trouble, California, a small town known for an unsolved train robbery that happened there in 1962. In the 1840s, Trouble was also home to one of Monk's distant relatives, an assayer who possessed skills invaluable to the small town, and exhibited many of the same obsessive compulsive traits as Adrian. Monk discovers that these seemingly uncorrelated historical facts are connected to the murder of a museum security guard in Trouble who was a retired San Francisco police officer.
The novel featured a short story entitled The Case of the Piss-Poor Gold, which was published before the novel was released in the November 2009 issue of Ellery Queen's Mystery Magazine. In the story, Artemis Monk, an assayer in the California gold rush town of Trouble in the 1840s, goes from determining the value of rocks to solving a murder.
