He explains that the events leading up to Webster's death began when Natalie bought several of Ludlow's titles in Los Angeles. Monk figures that Ludlow must have stolen Natalie's credit card receipt and used the number on the receipt to order the alligator head and ship it to her house in San Francisco with overnight shipping, and then he swiped the jaws off Natalie's porch before Natalie got home so that she never knew about the theft. Monk also figures out that Ludlow must have done some online research on Adrian Monk's various cases throughout the years (such as the 'Golden Gate Strangler' case), which explains his extensive knowledge of Monk and both of his assistants, Sharona and Natalie.
