“All right, then,” he said with a slight tone of admiration. “Breakfast of champions it is, Dr. Li.”

But as Vern followed Mike down the passageway, she held the cold metal of the can to her forehead, trying to keep back the headache until the pills hit.

They came to a hatch, what the Navy guys called a door, and Mike moved aside to let her pass through first. She thought he’d smell like old man or engine grease, but instead she smelled citrus.

“Don’t want you getting scurvy. We had to worry about that back in my day,” he said as he held out a freshly peeled orange to her.

She took the orange with a smile.

The rail-gun magazine extended below the turret, deeper into the ship, and that was where Vern sat, on an upturned plastic crate. She watched Mike welding and slowly ate the orange slices, savoring the tartness. This space was cramped, and she sat within arm’s reach of Mike. Looking through her goggles, she saw the flare of the welding torch create an eclipse-like profile of the old chief. Streaks of sweat tracked down his neck. Then the torch abruptly snapped off. He lifted his welding mask, eyes blinking at the smoke, and moved so she could see the rack that held the armatures for the rail-gun rounds.

“You see how it’s done, Dr. Li?” said Mike.

She slowly chewed her last orange slice, unsure what he meant.

“The welds? I want you to see how it’s done,” he said. “Up there, in the turret, we can do it your way, but you’re missing the technique, the art of it… If you just melt the surface of the wire or fitting and let it stick to the surface, it might be good enough for some lab, but it wouldn’t hold under the kind of pressures we could get in action. It’s about doing it smoothly, to ensure a proper mixing of the materials. Let me show you. Put my mask on and pass me your goggles.”

He motioned her over to the square of blue-foam padding he’d been kneeling on and handed her a pair of welding gloves.

“Those gloves should fit. I had to guess the size, but I think I got it. So this is structural, what we’re doing. Nobody’s going to see it, but everybody’s going to depend on it,” he said. “We’ll do a first pass then we’ll see how it goes.”

She knelt and he sat on the box behind her, reaching around to her left side to help her keep a steady hand as the torch flared. Back and forth they went until Mike let her use the torch without his help.

“There you go. Make a puddle, keep track of that as it builds,” he said, guiding her hand slowly across the seam where the armature rack connected to the deck. “We’ll need to make a few passes and then let it cool. Then again. Good technique comes with practice.”

“Why aren’t you using a laser welder?” asked Vern.

“Because there’s no reason to get fancy,” said Mike. “The old MIG welder works, so why change? No need to teach an old dog new tricks if the old ones still get the job done. You’ll learn that one eventually.”

He knew not to ask her name, so for now, she was just the new Twenty-Three.

Sechin opened the door and found her waiting under the sheets. Her eyes were wide open, unblinking, and tracked him with the kind of focus that came from a pill. To Sechin, she looked harder and, while still beautiful, slightly less inviting. The downsides of a professional’s existence. Once again, purpose trod upon pleasure, thought Sechin.

With the old Twenty-Three, everything was about what he wanted; with the new Twenty-Three, it was about what she wanted, first details on the Cherenkov program and now information on Directorate defenses in the northern Pacific.

Once he’d undressed and folded his clothes, he slipped under the sheets. They were orange this time. The delight of being under the covers with her warm, naked body was undeniable. It was that moment he savored, that first moment of contact with her skin as she quickly pulled the sheets over him.

She put a finger to her lips and he nodded. She lay back and closed her eyes. He watched her chest rise and fall with her steady breathing. He studied the tattoo at her waist. It was an intricate wreath of roses and snakes. He made out a cobra and a coral snake. There were two others that he could not identify. The roses were beautiful.

Then she turned on the recording of Sechin and the previous Twenty-Three’s lovemaking and began to arrange the thin blanket that would shield their conversation. He felt his cheeks flush with embarrassment.

“I think it is everything you are looking for,” said Sechin. “But I can’t guarantee that I was able to get it out clean. I tried but there is an urgency to all of this that —”

“Are you compromised?” she demanded, leaning on one elbow. She ran a finger down his chest and stopped at a fresh scar just below his navel. It was about an inch wide and was covered with the clear surgical glue used to seal the incision. Sechin had made the cut himself using the surgi-pen he found in the CIA dead drop behind an eel vendor’s stall at Shanghai’s Tangjiawan Lu wet market.

“Entirely,” he said with a dramatic sigh that released a warm cloud of stale tobacco and vodka under the covers. Twenty-Three wrinkled her nose with disappointment.

“This is not the time to make jokes,” she said. “So tell me, are you compromised?”

“I’m fine,” he said. “Like I said, I moved quickly because I had to. But I was careful. I always am.”

“Then let’s proceed,” she said. “And you can relax.”

“Happily,” he said. “Do you want to be on top?”

She shook her head and shifted her weight under him. Her hand probed around the area of his incision. He winced at the pain, and she apologized.

“Okay, I feel the chip,” she said. “Move a little to the left. Your left. There.”

The epidermal electronic reader hidden in the tattoo’s ink vibrated faintly as it downloaded Sechin’s file with a tickling sensation. He tried to kiss her and she pulled back.

“Stop!” she hissed. “Hold very, very still.”

The vibration continued for almost a minute and then both of them looked at each other as the sensation abruptly ceased.

“That wasn’t so bad,” he said. “Is it enough to end a war? Certainly wars have been started for less.”

“I need to go,” she said, trying to roll him off her. “This cannot wait.”

“Of course it can,” he said. “Besides, if I leave too quickly, won’t they think you’re not up to the job?”

With a resigned look, she nestled next to him. “You’re going to just hold me,” she said. This time, it seemed her command was not about the job. He grasped her shoulder and felt her tremble for a moment.

“If you were not scared, you would not be doing your job,” he said gently.

He’d begun to tell himself that they were making a connection when the recording stopped and she abruptly threw the sheet off them.

“Our time is up,” she said as she turned her back on him and began to get dressed.

“Of course it is,” he said.

“Remember, just don’t hit the bridge,” said executive officer Horatio Cortez as the Zumwalt passed Angel Island to starboard.

Two cups of coffee ago, the ship had cast off from the pier at Mare Island for the first time since its overhaul. It was an anxious moment. Had it not been for the Mentor Crew’s ease in handling the ship’s lines, Simmons was pretty sure the ship would still be in port; the kids who’d helped refit the ship’s systems had no idea how to get a warship under way. The Zumwalt had carefully processed from the shipyard at Mare Island down to Alcatraz Island, where it maneuvered to a very specific patch of the Bay, just off eBay Park’s pier.

The highly anticipated visit was timed to coincide with a San Francisco Giants game against the Washington Nationals. The Directorate well knew the Americans were refurbishing the ship by watching from above; they just didn’t know any details. So the public rollout at the baseball game on a night when military personnel were given free tickets was billed as a morale booster. Secretary of Defense Marylyn Claiburne was even coming in to throw the first pitch.
