“What, they’re afraid of soap too?”

“Not that kind of clean,” Rex said. “Untouched by midnight. You see, when something from the daylight world is disturbed during the blue time, it becomes part of their world. That changes it forever.”

“So how can you tell what’s clean?”

Rex took a deep breath. It was time to take over from Dess. “Haven’t you wondered how we knew you were a midnighter, Jessica?”

She thought hard for a second, then gave a defeated sigh. “I can’t keep track of all the stuff I’ve been wondering lately. But yeah, Dess seemed to know something from the moment we met. I just figured she was psychic.”

Melissa snorted quietly, her fingers drumming along with her music.

“Well, when things have been changed by the secret hour, they look different. To me, anyway. And you’re a midnighter, so you always look different. You’re naturally part of that world.” Rex pulled off his glasses.

Jessica’s face became completely clear to him. Rex could see the lines of exhaustion below her eyes and her alert, questioning expression, ready to absorb whatever they could tell her.

“I can also read the lore, marks left behind by other midnighters. There are signs all over Bixby, some of them left thousands of years ago.”

Jessica looked at him closely, possibly wondering if he was crazy. “And only you can see them?”

“So far.” He swallowed. “Can we try something, Jessica?”

“Sure.”

He led her to a museum case by the excavated wall. Under the glass was a collection of Clovis points, all from the Bixby area and all about ten thousand years old.

Although the label didn’t say so, one of the points had been retrieved from inside the rib cage of the “saber-tooth” skeleton embedded in the wall. The rest had been found in ancient campsites, burial mounds, and the snake pit. With his glasses off, Rex could instantly spot the difference.

That one spearhead stood out from the rest with burning clarity, every facet so distinct that he could envision how the ancient hammer had struck off each flake of stone. The Focus had clung to this piece of obsidian for millennia, and from his first glimpse of it Rex had known instinctively that it had pierced the heart of the beast on the wall.

This point had killed a darkling.

Rex’s naked eyes could also see subtle differences in the way it had been crafted—the meridian groove where the shaft had once been attached was deeper and sturdier, the edge much sharper. Ten thousand years ago this spearhead had been a piece of high technology, as advanced as some futuristic jet fighter. It might have been made of rock, but it had been the electrolytic titanium of its day.

“Do any of these… jump out at you?” he asked.

Jessica looked over the points carefully, her brow furrowed in concentration. Rex felt his breath catch. Last night he had allowed himself to wonder what it would be like if Jessica were another seer, someone else who could see the signs and read the lore. At last Rex would have someone to help him sift through the endless troves of midnighter knowledge, to compare interpretations of confusing and contradictory tales, to read alongside him.

Someone to share responsibility when things went wrong.

“This one’s kind of different.”

Jessica was pointing at a digging trowel, a stubby hand tool that wasn’t a spearhead at all. Rex let his breath out slowly, not wanting his disappointment to show, not wanting to feel the entire weight of it yet.

“Yeah, it is different. They used it to dig for root vegetables.”

“Root vegetables?”

“Big fans of yams, Stone Agers.” He put his glasses back on.

“So it’s a yam digger. That’s not what you brought me over here for, is it?”

“No,” he admitted. “I wanted to know if you could see something.”

“You mean, see the secret hour like you can?”

Rex nodded. “I can tell which of these spearheads killed a darkling. The touch lingers. I can see it.”

Jessica stared into the case and frowned. “Maybe my eyes are wrong.”

“No, Jessica. Different midnighters have different talents. We just don’t know what yours is yet.”

She shrugged, then pointed. “That’s a darkling skeleton up there, isn’t it?”

He was surprised for a moment, then nodded, realizing that she’d seen a creature like it in the flesh.

“Wow. So these things really were around ten thousand years ago,” she said. “Shouldn’t they be extinct by now or something? Like dinosaurs?”

“Not in Bixby.”

One of her eyebrows raised. “Rex, there aren’t any dinosaurs in Bixby, are there?”

He had to smile. “Not that I’ve seen.”

“Well, that’s something.”

Rex silently led her back toward the table. It could have changed everything if Jessica had turned out to be a seer. He swallowed, unable to speak for a moment, then found part of last night’s speech on the tip of his tongue.

“Darklings almost went extinct, Jessica, but instead they hid themselves in the blue time. It’s been a long time since they lived in the world with the rest of us.”

“That must have been exciting, being chased around by those things twenty-four seven.”

“Twenty-five seven,” Rex corrected her. “Humans weren’t the top of the food chain back then. People had to deal with tigers and bears and dire wolves. But the darklings were the worst. They weren’t just stronger and faster, they were smarter than us. For a long time we were completely defenseless.”

They sat back down at the table, the darkness of the unused corner of the museum surrounding them. Melissa looked up at Rex, her satisfied expression showing that she could taste his disappointment.

“How did anyone survive?” Jessica asked.

Dess leaned forward. “The darklings are predators, Jessica. They didn’t want to wipe human beings out, just take enough to keep themselves fed.”

Jessica shivered. “What a nightmare.”

“Exactly,” Rex said. A small group of tourists was descending the ramp, and he lowered his voice. “Imagine wondering every night if they would be coming to feed. Imagine having no way to stop them. They were the original nightmares, Jessica. Every monster in folklore, every mythological monster, even our instinctive fear of the darkness, they’re all based on ancient memories of darklings.”

Dess’s eyes narrowed as she leaned forward, also lowering her voice. “Not all darklings look like panthers, Jessica. You haven’t even met the really scary ones yet.”

“Oh, wonderful,” Jessica said. “And they all live in Bixby now?”

“We’re not sure about that,” Dess said. “But Bixby’s the only place with midnight that we know of. Even up in Tulsa, twenty miles from here, the blue time doesn’t come.”

“For some reason, Bixby’s special,” Rex said.

“Great,” Jessica said. “Mom wasn’t kidding when she said moving here would require some adjustments.”

She slumped in her chair.

Rex tried to remember the threads of his speech. “But don’t forget, we humans won. Gradually we discovered ways to protect ourselves. It turned out that new ideas scared the darklings.”

“Ideas? Scared that thing?” She looked across the room at the darkling skeleton.

“New tools, like forged metal and alloys,” Dess said. “And new concepts, like mathematics. And the darklings were always afraid of the light.”

“Fire was the first defense,” Rex said. “They’ve never gotten used to it.”

“Well, that’s a relief,” Jessica said. “I’ll make sure I’ve got a flamethrower next time the secret hour comes around.”

Dess shook her head. “It won’t help you. Fire, electronic stuff, car engines, none of those technologies works in the midnight hour. You think we rode bicycles halfway across Bixby last night for the exercise?”

“That’s why the blue time was created,” Rex said. “A few thousand years ago, when the darklings were being pushed into the deepest forest by steel weapons and fire, they created it as a sanctuary for themselves.”
