A 911 call from a judge identifies the man who is about to murder her as rich and obscenely fat financier Dale Biederbeck. But ""Dale the Whale"" weighs over 800 pounds and can‘t get up from his bed, making it impossible for him to have commited the murder, despite the 911 call and the testimony of a ten-year-old witness who saw an extremely fat man through the window of the judge‘s house. The fact that Biederbeck sued Monk‘s wife for libel after she criticized his ethics in a newspaper article gives Monk added incentive to find him guilty. While Monk and Captain Stottlemeyer try to figure out how Dale could have committed the murder, Sharona gets her chance to play Lois Lane, or rather Florence Nightingale, by briefly serving as Biederbeck‘s nurse instead of Monk‘s. She also finds herself attracted to Dale‘s private physician, Christian (kristy AN) Vezza.
