Physicist Leonardo Vetra smelled burning flesh, and he knew it was his own. He stared up in terror at the dark figure looming over him. "What do you want!"

"La chiave," the raspy voice replied. "The password."

"But… I don’t—"

The intruder pressed down again, grinding the white hot object deeper into Vetra’s chest. There was the hiss of broiling flesh.

Vetra cried out in agony. "There is no password!" He felt himself drifting toward unconsciousness.

The figure glared. "Ne avevo paura. I was afraid of that."

Vetra fought to keep his senses, but the darkness was closing in. His only solace was in knowing his attacker would never obtain what he had come for. A moment later, however, the figure produced a blade and brought it to Vetra’s face. The blade hovered. Carefully. Surgically.

"For the love of God!" Vetra screamed. But it was too late.

High atop the steps of the Pyramid of Giza a young woman laughed and called down to him. "Robert, hurry up! I knew I should have married a younger man!" Her smile was magic.

He struggled to keep up, but his legs felt like stone. "Wait," he begged. "Please…"

As he climbed, his vision began to blur. There was a thundering in his ears. I must reach her! But when he looked up again, the woman had disappeared. In her place stood an old man with rotting teeth. The man stared down, curling his lips into a lonely grimace. Then he let out a scream of anguish that resounded across the desert.

Robert Langdon awoke with a start from his nightmare. The phone beside his bed was ringing. Dazed, he picked up the receiver.
