Jake left one bolt in place so he didn't have to lift the metal plate. He used Regan's crowbar to wedge the plate away from the concrete vault then, using it as a lever, rotated the metal plate away from the opening. Inside was the casket. The same make and model as all the others. He hesitated. Did he really want to disturb Norman Reese's grave? He didn't, but his orders were to acquire the book and stop any further marauding of WWII graves. Regan had offered him a deal and he took it. He was a man of his word. When the deal was consummated and the book in his hands, the grave robbing would stop. If President Rudd wanted to pursue what happened to the contents of the graves, she could do that through other means. His objective was to retrieve the book. He thought about Wiley's words to him last year when he was pursuing a terrorist, Meet the objective, the how doesn't matter.
