Monk and Natalie investigate the murder of a security guard at a Guiness museum, which includes the theft of a robot that simulates the eating of boiled eggs. Don't ask. Along the way, Monk meets a sweet old lady (Rowlands) who treats him like her son, and she indeed did have a son, who died at age 3. She lives next door to the guard's killer and asks Monk for help in keeping the guy quiet (he constantly bangs away on drums). A friendship flourishes between Monk and the old broad, until Monk begins to suspect the old lady of being in cahoots with the neighbor, who also robs a jewelry store and kills the proprietor in the process. Rowlands always livens up anything she does, and is wonderful here as a lonely senior. Monk is feeling loved for the first time in a long time, and unfortunately begins to back away from Natalie as he grows closer to the old lady.,
