She puts her finger to it.

“Yep,” Marty says, “saw that, too.”

“What is it?” Luke asks.

“An injury maybe?”

“An injury she thinks we should see.”

As if he’s reading her mind, Marty goes back to the other photos. If they aren’t already seeing the connection, they will be shortly.

Lacey didn’t just want them to see how much the once-happy couple used to love the beach. She wanted them to see Jordy shirtless; she wanted them to see what was on his shoulder up until she snapped a shot of him sleeping.

Marty was right. In all the beach shots, Jordy sports a large tattoo on his shoulder, and it looks like it’s mostly words.

“Can you zoom?”

“I can try.”

It only takes a few clicks before they see it, and when they do, Luke rears back from the computer as if it’s a coiled snake. They can’t even read all the words, but they don’t need to, because the name of the Bible verse is tattooed larger than the verse itself. The same verse somebody—Jordy?—used in crackpot chat rooms to try to both calm and establish communication with people who wanted to inflict violence on groups they deemed morally repugnant.

“What the fuck?” Marty whispers.

“So someone’s using the same Bible verse in all these chat rooms, and Jordy’s got the same verse on his shoulder up until . . . recently, I guess? When was the photo of his back taken?” He clicks on it, opens a new window containing the photo’s data points. “Three weeks ago.”

Charley says, “We know the photo was taken three weeks ago. We don’t know if he had that tattoo removed three weeks ago.”

“No, but we know three weeks ago is when Lacey Shannon decided that somebody needed to know that her boyfriend got his tattoo removed,” Luke says. “And that date comes after the dates on these chats where the same passage from Corinthians was used. So if it’s Jordy talking to these whack jobs, inviting them to chat or whatever—”

“He’s not just inviting them to chat,” Marty says, “he’s inviting them to find their fire. Is that how you ask somebody out to coffee?”

“No,” Charley says.

“Find your fire,” Luke whispers.

“My God has a finger of fire,” Charley repeats.

Nobody says anything for a bit.

“Not smart, using a tattoo on your body to communicate with potential psychopaths,” Charlotte says.

“Whether he’s smart or not,” Marty says, “something happened during these conversations that convinced him he needed to get part of his skin taken off. Must have been major.”

“And Lacey noticed,” Luke says.

“And thought you should notice, too,” Charlotte says.

“This isn’t her personal flash drive,” Marty says. “Every picture on here is the same. Jordy’s shirtless in every one. She’s showing us that tattoo.”

“And that he had it removed,” Luke says.

“OK. So . . . the seismic maps?” Charlotte asks.

The third detail seems to stump all of them.

Then Charlotte feels her face get hot all of a sudden.

“Shit,” she whispers.

“What?” Luke asks.

“Marty, what else goes into building a tunnel besides the drills?” she asks.

“Probably something to stabilize the hole with. Equipment to drag away the broken rock you’ve drilled through. Explosives to . . .”

Marty’s face drains of color.

“What, guys?” Luke asks.

“I had it backwards,” Charley says.

“Backwards how?” Luke asks.

“Maybe the one that said the tunnel’s going to be twice as hard to build isn’t the real one,” she says. “It’s the fake one.”

“Because Jordy wants more explosives than he’s actually going to need,” Marty adds.

“Because they make fire,” Charlotte says. “And that’s what he wants to give to these lunatics. Fire. ‘It will be revealed with fire, and the fire will test the quality of each person’s work.’”

“Fire purchased through entirely legal means,” Marty says.

Luke’s the one to finally break the long silence. “Hate in his heart. That’s what she said: ‘Jordy is a man with hate in his heart.’”

“She wasn’t trying to make the case that he was a woman beater. She was saying what she could to get you to throw him in a cell right away. That way she could . . .” Marty swallows.

Charley finishes the sentence for him. “She could make the case that Jordy’s a terrorist.”

Luke turns his attention to the computer and its mess of open windows.

“Well,” he finally says, “does she?”

When the phone rings, Luke yelps in surprise. Marty jumps, but manages to keep his reaction silent.

Charlotte walks to the handset, checks the caller ID.

“Unavailable,” she reads aloud.

Luke just shakes his head. Maybe he’s already got some sense of who it is, but he doesn’t want to believe it.

Charlotte answers using speakerphone.

“This is a very interesting conversation,” Cole Graydon says. At first, she assumes he’s driving, but the sound of rushing air is too deep and steady. He must be in the air.
