Creeper Much?

"I saw a few of the incidents myself. But mostly I heard about them, and when I did, I quizzed people until I'd got a more or less full account." -pg 14

Spidy man

On the fourth page, Kathy quickly identifies Tommy and Ruth as important characters to the book. Not only are they the reason Kathy embarks on an extensive flashback to give the new characters a base, but they are involved in her present, her career as a carer. However, Kathy, Ishiguro really I suppose, seems to focus more on Tommy and adds details about Ruth as an after thought. In fact, Kathy goes full out sleuth on Tommy. She follows him, researches him, and interviews people about him. For her work, she is able to lay out and discover patterns in his behavior. This is a little strange to me. Why would Ishiguro emphasize Kathy and Ruth's relationship at first, but then write about Kathy's obsession with Tommy. My spider senses tell me that Tommy may become a issue of conflict between Ruth and Kathy.
