Kate is annoyed when Charlie released Roxanne without consulting her. On her way out of the station, Roxanne sees one of her main clients—a man she calls the Silver Medallist—better known to Charlie as Graham Holbeck, Kate's father. The next day, Kate, Charlie and Bill are called to an apartment where they find Roxanne beaten to death. Marvin Hoppe, one of her clients is still at the scene and declares his innocence, saying he was in love with Roxanne. Charlie is convinced that Marvin had something to do with the murder. Deakin is put on Marvin's tail while Charlie and Kate go back to the scene, searching for clues. Charlie interviews Roxanne's next door neighbour and discovers that Graham Holbeck was in fact in her room last night. Charlie confronts Holbeck with this information. Holbeck of course denies everything, but feeling the pressure he goes to his daughter, who lies and provides an alibi for her father. Charlie recognises the lie for what it is and confronts Kate. The argument escalates out of control. The engagement is off and both are left to ponder the future of their relationship.
