Riley Sullivan Walker's Links
For a long time, Holly thought Riley was too drunk and incompetent to ever catch on to her secret. Of course, she was frequently just as far out of her gourd on something or other, so the two of them were a perfect match for eachothers' wits in that way.
She frequently snipes at Riley's status as a private investigator, questioning if she's really running a business or if she's just some curious lady in a coat with a camera and a notebook. Riley would probably do a better job in Holly's profession than she has been, though.
