Who is Roger Hammond from A Savage Place: A Spenser Novel and what is their importance?

Roger Hammond is the head of Summit Pictures. Roger Hammond made some bad investments with the studio's money five or six years before the novel begins and was forced to go to the mob to bail him out before anyone could find out. As a result, the mob got involved in the movie industry and everyone, including Hammond, got rich. However, Felton began stealing money and Franco found out. Franco began blackmailing Felton, which is the payoff that Mickey saw. This payoff begins Candy's investigation, causing the mob to become concerned that Candy might prove the connection and bring them all down. As a result, Franco was sent to scare Candy off, but it did not work.
