The next morning, Sharona shows up at Monk's apartment, Monk having called her the night before. Stottlemeyer also shows up, and Monk explains that he believes Ludlow himself killed both Ronald Webster and Ellen Cole. He remembers how Ludlow said to him that he hangs around with Lieutenant Dozier for a few days as he waits for an unusual murder to come along, but Monk doesn't believe Ludlow waits - he believes that Ludlow befriends a random person he meets at a book signing, follows them for a while, kills them, finds out who is in their life, and then frames the least likely person for the crime.
