01E08 - Mr. Monk and the Other Woman

When a lawyer and his assistant are murdered, suspicion falls on a disgruntled client whose burnt file is found in the wastebasket. When the suspect, Grayson, is also murdered, Stottlemeyer is certain that Grayson's neighbor, a pretty blonde named Monica Waters who has been feuding with Grayson for two years about her garage, is guilty of all three murders. But Monk is attracted to Monica, who bears a slight resemblance to Trudy. Because Monica's absent husband had OCD, she understands Monk in a way that Sharona can't, which of course adds to the attraction. Even her garage is perfect, exactly the way Monk would want his garage to be organized if he ever had one. A touching bond forms between them until a call from Stottlemeyer leads him to suspect that Monica may really be the murderer.
