Page 182 of The Lost Symbol

Mercury: as depicted by its most ancient alchemical symbol.

The Ouroboros: the symbol of wholeness and at-one-ment.

Solomon still insisted these seven symbols were a “message.” But if this was true, then it was a message Langdon had no idea how to read.

The Escalade slowed suddenly and turned sharply right, onto a different surface, as if into a driveway or access road. Langdon perked up, listening intently for clues as to their whereabouts. They’d been driving for less than ten minutes, and although Langdon had tried to follow in his mind, he had lost his bearings quickly. For all he knew, they were now pulling back into the House of the Temple.

The Escalade came to a stop, and Langdon heard the window roll down.

“Agent Simkins, CIA,” their driver announced. “I believe you’re expecting us.”

“Yes, sir,” a sharp military voice replied. “Director Sato phoned ahead. One moment while I move the security barricade.”

Langdon listened with rising confusion, now sensing they were entering a military base. As the car began moving again, along an unusually smooth stretch of pavement, he turned his head blindly toward Solomon. “Where are we, Peter?” he demanded.

“Do not remove your blindfold.” Peter’s voice was stern.

The vehicle continued a short distance and again slowed to a stop. Simkins killed the engine. More voices. Military. Someone asked for Simkins’s identification. The agent got out and spoke to the men in hushed tones.

Langdon’s door was suddenly being opened, and powerful hands assisted him out of the car. The air felt cold. It was windy.

Solomon was beside him. “Robert, just let Agent Simkins lead you inside.”

Langdon heard metal keys in a lock . . . and then the creak of a heavy iron door swinging open. It sounded like an ancient bulkhead. Where the hell are they taking me?!

Simkins’s hands guided Langdon in the direction of the metal door. They stepped over a threshold. “Straight ahead, Professor.”

It was suddenly quiet. Dead. Deserted. The air inside smelled sterile and processed.

Simkins and Solomon flanked Langdon now, guiding him blindly down a reverberating corridor. The floor felt like stone beneath his loafers.

Behind them, the metal door slammed loudly, and Langdon jumped. The locks turned. He was sweating now beneath his blindfold. He wanted only to tear it off.

They stopped walking now.

Simkins let go of Langdon’s arm, and there was a series of electronic beeps followed by an unexpected rumble in front of them, which Langdon imagined had to be a security door sliding open automatically.

“Mr. Solomon, you and Mr. Langdon continue on alone. I’ll wait for you here,” Simkins said. “Take my flashlight.”

“Thank you,” Solomon said. “We won’t be long.”

Flashlight?! Langdon’s heart was pounding wildly now.

Peter took Langdon’s arm in his own and inched forward. “Walk with me, Robert.”

They moved slowly together across another threshold, and the security door rumbled shut behind them.

Peter stopped short. “Is something wrong?”

Langdon was suddenly feeling queasy and off balance. “I think I just need to take off this blindfold.”

“Not yet, we’re almost there.”

“Almost where?” Langdon felt a growing heaviness in the pit of his stomach.

“I told you—I’m taking you to see the staircase that descends to the Lost Word.”

“Peter, this isn’t funny!”
