Scott Sigler - Nocturnal - A Novel

“It doesn’t quack ,” she said. “And it doesn’t bark either. All the DNA I recovered was definitely human.”

Robin had given case results to Rich many times before. He was always a bit of an asshole, but normally he seemed interested in every detail. Why didn’t he care about the details now?

“I only have evidence for one assailant,” Robin said. “I have saliva and hair from a person , Rich — can your little mind process that?”

Bobby was smiling, and not the way men did when they thought she was pretty. He seemed to be enjoying the fact that she pushed back. The veins in the sides of Rich’s thinning temples throbbed and pulsed — they looked like they might pop at any moment.

She’d lost her temper a little, but now she seemed to have Rich’s full attention. He looked angry. Calm, but angry.

“So,” he said, “you’re telling me this can’t be an animal attack?”

Robin paused. She had genetic evidence of a human killer, but the tooth marks were definitely from some kind of animal. There had to be some element of the animal on Oscar’s body, she just hadn’t found it yet.

“I’m sure an animal was involved, but what I’m telling you is I have specific evidence that can help you find the guy responsible for Oscar’s death,” she said. “I found indicators of three chromosomes, two Xs and a single Y.”

“Three?” Bobby said. He seemed to perk up at the first mention of genetics. “You said it was one killer. Guys are XY. Wouldn’t three chromosomes indicate a second killer?”

Verde glared at Bobby.

Bobby shrugged at him. “Rich-o, seems like we’d need to know this stuff, don’t you think?”

Verde’s jaw muscles twitched. He turned back to stare at Robin. “Go ahead, busy bee — tell me what you found.”

He’d looked angry before. Now he looked downright furious.

“If there was a second male assailant, I’d have found evidence of another Y chromosome,” she said. “Even if a second assailant was female, I’d have at least found evidence of a third X chromosome. That leads me to believe Oscar’s killer is trisomal , which means he has three sex chromosomes instead of the normal two. If the assailant is XXY, he probably has a condition called Klinefelter’s syndrome.”

Bobby nodded. He had the same look in his eye she’d often seen in Bryan — to guys like them, clues were crack cocaine that got their pulses racing. “I’ve heard of Klinefelter’s,” he said. “But that’s not the only possibility, right? I mean, couldn’t two people have identical chromosomes? Like twins? Not the identical kind, but fraternal twins?”

Robin smiled in surprise. For a layman, that was a brilliant question.

“It’s possible the killers could have been male and female twins,” she said. “And technically, normal brothers with the same father have the same Y chromosome. However, I’m almost positive the samples show we’re dealing with a single killer. I’ll run a different kind of test to be sure.”

Verde’s eyes narrowed. “And what kind of test would this be?”

“It’s called a karyotype,” Robin said. “We need living cells for that, but the saliva on the body was only a few hours old, so we have plenty. A karyotype shows the total number of chromosomes in an organism. You, me, Bobby, pretty much every person you know has forty-six chromosomes — that’s normal. If the test shows the perp has forty-six, that means my extra X is from a second killer. But if the test shows an individual with forty-seven chromosomes, it means we have just one killer with a unique genetic disposition that will help you track him down.”

Bobby smiled. “Sweet,” he said. His gold tooth made him look like a pimp.

“Metz didn’t run tests like that,” Rich said. “You shouldn’t, either. And we don’t need that test — we’ve got some leads we can’t talk about.”

She noticed Bobby suddenly look at Rich in surprise. If there were such leads, it was news to the younger of the two partners.

Robin crossed her arms over her chest. “Are you telling me you don’t want more leads? If our guy has Klinefelter’s, he could be confused about his gender or possibly express sexual deviation that’s been recorded. You could look for mixed-gender support groups, or—”

“Do your job,” Verde said. “You get paid to look at stiffs. You don’t get paid to solve cases. Leave the detective work to the detectives. Just do the basics. Bobby, let’s go.”

Verde stormed off. Bobby rolled his eyes and smiled apologetically before following Verde out.

Robin spun slightly in her chair, watching them go. So strange — why wouldn’t Rich want to exhaust every angle to solve a horrific murder? Maybe that was a question she didn’t need to ask. Verde had the authority of Chief Amy Zou behind him, and he was right about one thing — solving crimes wasn’t her job. So maybe Rich had her there, but on the other hand, he wasn’t her boss. Neither was Chief Zou. They could make suggestions, but they couldn’t tell her what tests not to run.

Robin could use the new RapScan machine to run the karyotype. All she had to do was load DNA samples into the machine’s cartridges, which took about fifteen minutes. From there, the whole process was automated — it only took a few hours to complete. She’d start the test now, then pack up the work she could finish at home and get out of there.

When she came back in the morning, the karyotype results would be waiting for her.

The Artist and His Subject

Rex drew. He was a good drawer, he knew that. Mrs. Evans, his art teacher at Galileo, she said he had potential . No one ever said that to him, about anything. Not since his dad had died, anyway.

Mrs. Evans was okay, but he had to hide his best drawings from her. The ones with the guns, the knives, the chain saws, the ropes — things like that. She’d seen some of those drawings and pretty much flipped out, so Rex just kept them to himself.

He also now knew he couldn’t let other kids see his pictures. Not ever , or BoyCo might hurt him even worse than before.

But if they did come after him again, Oscar Woody wouldn’t be with them.

Because Oscar Woody was dead.

Rex had made so many drawings. He’d even drawn one of the strange faces he saw in his dreams. That one had gone up on the walls with all the others, labeled with a name that he heard most often during those visions: Sly .

Rex drew. His pencil outlined the oval of a head, then the shapes of eyes, the contours of a nose. Quietly, he worked away, adding lines and shading. Gradually, the face became recognizable.

The sound of pencil on paper picked up speed. A body took form. So did a chain saw. So did splashes of blood.

Rex felt warm. His chest tingled inside.

Erase that part of the nose, redraw … adjust the corners of the mouth, coax the lines and shapes and shades into expressions of agony, of terror .

He felt his own heartbeat pulsing in his neck, bouncing through his eyes and forehead.

Erase the bicep, darken that line … the chain saw had just passed through the arm, severing it in a splatter of blood.

Rex felt himself stiffen in his pants.

He moaned a little as he erased the eyes. They weren’t quite right. Make them wider. Make them full of fear .

Fear of Rex.

He had drawn Oscar Woody, concentrated on Oscar Woody, and now Oscar Woody was dead.

Maybe it hadn’t been coincidence.

And, maybe, Rex could make it happen again.

The new face?

Jay Parlar, the boy who had put the pieces of wood under Rex’s wrist and elbow.
