With the fetid stench and lack of oxygen choking the strength from his body, Langdon realized he only had time for one more effort. He also knew he would need both arms.
Regrouping, he placed the tapered edge of the bone against the crack, and shifting his body, he wedged the bone against his shoulder, pinning it in place. Careful not to dislodge it, he raised both hands above him. As the stifling confine began to smother him, he felt a welling of intensified panic. It was the second time today he had been trapped with no air. Hollering aloud, Langdon thrust upward in one explosive motion. The casket jostled off the floor for an instant. But long enough.
