“C’mon!” Norman yelled to April, the two of them running across the room to shield themselves behind the Mainz Bible display case. Pieces of the wall blew apart as gunfire whizzed by their heads and struck it. They ducked.

“I thought you were going to kill me,” April shouted, wiping water away from her eyes.

Norman raised his voice over the din of the alarm. “You said improvise.” He checked the gun clip, then leaned around the display case and fired off a couple rounds. “They won’t stick around for us. They’ve got the Gutenberg.”

“They have one Gutenberg,” April said. “I don’t think it’s the one they need.”

“What do you mean, one? The library has another?”

“Not that the public knows about.”

A few rounds ricocheted off the bulletproof glass of the Mainz Bible display case as the agents’ feet splashed by. “They’re not headed for the exit,” Norman said. “Do you think they know where the other Gutenberg is located?”

“They must,” April said. “Is it safe for us to move?”

Norman pulled a couple coins out of his pocket and threw them toward the far corner of the room. Bullets ripped the ground where the coins landed. Norman spun around the opposite side of the display case and fired a single shot at the exposed agent. The agent fell face-first into a pool of water, his head cracking on the floor. “Now it’s safe,” Norman said.

The two of them sloshed toward a flight of stairs that led to the wraparound balcony. As they reached the top step, the resounding alarm stopped, as did the torrent of water.

“How did you know about the alarm?” April asked, heading up another set of steps toward the Minerva mosaic that overlooked the Great Hall.

“Dr. Winter showed the display-case code to me: Taurus, Leo, Aries, Aquarius. He also showed me the fire code set to a five-minute delay, the code you gave them.”

“The delay was built in to allow someone to get the Gutenberg to a secure location before the water destroyed it,” April said. “Who knew it would save my life?”

“Will we get to the second Gutenberg before they do?”

“I don’t know,” April answered. “And here’s something else I don’t know: if they planned to take the other copy, why didn’t they want to keep me around to help get that one too?”

“Apparently they didn’t think they needed you in the first place.”

They exited a door that led into a long hallway on the second floor. They ran until April stopped before a set of ornate bronze doors. She pointed to a panel set in the upper left-hand corner. “The signs of Gutenberg are everywhere if you know where to look.”
