Goodbye Mr. Hollywood. American English

Nick Lortz is sitting outside a cafe in Whistler, a village in the Canadian mountains, when a stranger comes and sits next to him. She's young, pretty, and has a beautiful smile. Nick is happy to sit and talk with her. But why does she call Nick 'Mr Hollywood'? Why does she give him a big kiss when she leaves? And who is the man at the next table the man with short white hair? Nick learns the answers to these questions three long days later in a police station on Vancouver Island.
