Monk examines the scene and notices streaks on the floor, some hydraulic fluid, and a drop of blood in the bathtub - clues that suggest that this is where Webster was killed. He also notices that their killer apparently was very messy and left behind basically everything except a name and a phone number, and is somewhat confused - why would someone who'd killed a guy in a very clever way suddenly become so messy? Monk also notices that the victim was a fan of Ludlow's books, judging by the fact that he has all but the latest title on his bookshelf. They also find a pizza box from Sorrento's with a receipt dated to Thursday night, and Natalie begins to wonder if she and Julie came very close to encountering Webster or spotted him and never recognized him.
