When Monk and Natalie are waiting outside a crime scene, they happen to overhear a call on the police radio mentioning a homicide. The victim's name? Julie Teeger. Natalie, understandably terrified to hear her daughter's name, hops into Captain Stottlemeyer's brand-new car and speeds off to the scene of the crime. The victim doesn't turn out to be Natalie's daughter, which is good news for Natalie, though not for the dead Julie Teeger's distraught husband, to whom Stottlemeyer makes a promise that he'll track down the killer. But just as Monk is in the middle of examining the crime scene, the police hear another call about a dead bicyclist. The second victim's name? Julie Teeger! This death appears at first to be a hit-and-run accident, but once Monk takes a closer look, he realizes something bizarre is going on: someone in San Francisco is killing Julie Teegers.
