This is one of a series of books based on the character of Adrian Monk from the TV show "Monk". In this book, Monk and his assistant Natalie travel to a town that was established at the time of the California Gold Rush to solve a murder. While there they discover a 50 year old mystery of stolen gold. Unable to leave something unsolved, Monk decides to locate the missing gold as well as determine who killed the museum security guard. This is an entertaining read and definitely feels like Monk from the TV show. However, he seems even more obsessed with everything around him than the television character which gets a little wearing.
