Gabrielle attends a party in New York to celebrate the success of her friend, Quinton Jones, the artist. He tells her that his invitation is related to some information he has for her. The next day, Gabrielle wakes up in a daze to the knocking on her door. The police tells her at the station that Quinton Jones has been killed in an auto accident the previous night and believes she was the last person to see him alive.

A rather desperate Gabrielle calls Alexander for help.
