With the skull of St. Peter in hand, Margaret and Mr. Cromarty meet with Santino Scarpatti and Richard Greenstreet at a warehouse to auction off the skull to the highest bidder. When Sam suddenly appears with a briefcase full of money, Margaret allows him to stay and bid on the skull, wishing him luck.
