Following the death of his beloved psychiatrist, Dr. Charles Kroger, from a sudden heart attack, Monk decides to buy a house to get away from the neighbor girl, who constantly plays a Chopin prelude on the piano that reminds him too much of Dr. Kroger. The house he purchases is that of Joseph Moody, an elderly man who died recently in what the police presumed was an accident in which he fell down a flight of stairs. Needing help with a minor repair, Monk hires “Honest“ Jake Phillips, a handyman who is everything but handy or honest. While learning that the house could literally be a “money pit,“ Monk discovers that the former owner's death was no accident, but discovers the truth too late, putting himself, and Natalie, in grave danger. Monk decides it's time to try out a new psychiatrist.
