Addison has been selling stolen jewelry through the store but he really has his eye on the Kincannon family jewels that are for sale. James Kincannon wants the collection back but technically, they belong to his mother and his family is heavily in debt, thus the planned sale. James needs the money to replay money Slade's dead son embezzled from the company where they work. James had covered the loss in the books but an audit is planned due to a merger. Addison has been practicing stealing the jewels at night without the benefit of sight with the aid of his girlfriend and fellow employee Adele Bentley.
