“Stain it, light it and shoot the son of a bitch on the one-to-one.”

It took her only two tries to get a crisp Polaroid. She felt like she’d found a hundred-dollar bill in the street.

“Vacuum the area and then go back to the post. Walk the grid,” he told her.

She slowly walked the floor, back and forth. One foot at a time.

“Don’t forget to look up,” he reminded her. “I once caught an unsub because of a single hair on the ceiling. He’d loaded a.357 round in a true.38 and the blowback pasted a hair from his hand on the crown molding.”

“I’m looking. It’s a tile ceiling. Dirty. Nothing else. Nowhere to stash anything. No ledges or doorways.”

“Where’re the staged clues?” he asked.

“I don’t see anything.”

Back and forth. Five minutes passed. Six, seven.

“Maybe he didn’t leave any this time,” Sachs suggested. “Maybe Monelle’s the last.”

“No,” Rhyme said with certainty.

Then behind one of the wooden pillars a flash caught her eye.

“Here’s something in the corner… Yep. Here they are.”

“Shoot it ’fore you touch it.”

She took a photograph and then picked up a wad of white cloth with the pencils. “Women’s underwear. Wet.”

“Semen?”

“I don’t know,” she said. Wondering if he was going to ask her to smell it.

Rhyme ordered, “Try the PoliLight. Proteins will fluoresce.”

She fetched the light, turned it on. It illuminated the cloth but the liquid didn’t glow. “No.”

“Bag it. In plastic. What else?” he asked eagerly.

“A leaf. Long, thin, pointed at one end.”

It had been cut sometime ago and was dry and turning brown.

She heard Rhyme sigh in frustration. “There’re about eight thousand varieties of deciduous vegetation in Manhattan,” he explained. “Not very helpful. What’s underneath the leaf?”

Why does he think there’s anything there?

But there was. A scrap of newsprint. Blank on one side, the other was printed with a drawing of the phases of the moon.

“The moon?” Rhyme mused. “Any prints? Spray it with ninhydrin and scan it fast with the light.”

A blast of the PoliLight revealed nothing.

“That’s all.”

Silence for a moment. “What’re the clues sitting on?”

“Oh, I don’t know.”

“You have to know.”

“Well, the ground,” she answered testily. “Dirt.” What else would they be sitting on?

“Is it like all the rest of the dirt around there?”

“Yes.” Then she looked closely. Hell, it was different. “Well, not exactly. It’s a different color.”

Was he always right?

Rhyme instructed, “Bag it. In paper.”

As she scooped up the grains he said, “Amelia?”

“Yeah?”

“He’s not there,” Rhyme said reassuringly.

“I guess.”

“I heard something in your voice.”

“I’m fine,” she said shortly. “I’m smelling the air. I smell blood. Mold and mildew. And the aftershave again.”

“The same as before?”

“Yes.”

“Where’s it coming from?”

Sniffing the air, Sachs walked in a spiral, the Maypole again, until she came to another wooden post.

“Here. It’s strongest right here.”

“What’s ‘here,’ Amelia? You’re my legs and my eyes, remember.”

“One of these wooden columns. Like the kind she was tied to. About fifteen feet away.”

“So he might have rested against it. Any prints?”

She sprayed it with ninhydrin and shone the light on it.

“No. But the smell’s very strong.”

“Sample a portion of the post where it’s the strongest. There’s a MotoTool in the case. Black. A portable drill. Take a sampling bit – it’s like a hollow drill bit – and mount it in the tool. There’s something called a chuck. It’s a -”

“I own a drill press,” she said tersely.

“Oh,” Rhyme said.

She drilled a piece of the post out, then flicked sweat from her forehead. “Bag it in plastic?” she asked. He told her yes. She felt faint, lowered her head and caught her breath. No fucking air in here.

“Anything else?” Rhyme asked.

“Nothing that I can see.”

“I’m proud of you, Amelia. Come on back and bring your treasures with you.”

CAREFUL,” RHYME BARKED.

“I’m an expert at this.”

“Is it new or old?”

“Shhh,” Thom said.

“Oh, for Christ’s sake. The blade, is it old or new?”

“Don’t breathe… Ah, there we go. Smooth as a baby’s butt.”

The procedure was not forensic but cosmetic.

Thom was giving Rhyme his first shave in a week. He had also washed his hair and combed it straight back.

A half hour before, waiting for Sachs and the evidence to arrive, Rhyme had sent Cooper out of the room while Thom slicked up a catheter with K-Y and wielded the tube. After that business had been completed Thom had looked at him and said, “You look like shit. You realize that?”

“I don’t care. Why would I care?”

Realizing suddenly that he did.

“How ’bout a shave?” the young man had asked.

“We don’t have time.”

Rhyme’s real concern was that if Dr. Berger saw him groomed he’d be less inclined to go ahead with the suicide. A disheveled patient is a despondent patient.

“And a wash.”

“No.”

“We’ve got company now, Lincoln,”

Finally Rhyme had grumbled, “All right.”

“And let’s lose those pajamas, what do you say?”

“There’s nothing wrong with them.”

But that meant all right too.

Now, scrubbed and shaved, dressed in jeans and a white shirt, Rhyme ignored the mirror his aide held in front of him.

“Take that away.”

“Remarkable improvement.”

Lincoln Rhyme snorted derisively. “I’m going for a walk until they get back,” he announced and settled his head back into the pillow. Mel Cooper turned to him with a perplexed expression.

“In his head,” Thom explained.

“Your head?”

“I imagine it,” Rhyme continued.

“That’s quite a trick,” Cooper said.

“I can walk through any neighborhood I want and never get mugged. Hike in the mountains and never get tired. Climb a mountain if I want. Go window-shopping on Fifth Avenue. Of course the things I see aren’t necessarily there. But so what? Neither are the stars.”

“How’s that?” Cooper asked.

“The starlight we see is thousands or millions of years old. By the time it gets to Earth the stars themselves’ve moved. They’re not where we see them.” Rhyme sighed as the exhaustion flooded over him. “I suppose some of them have already burned out and disappeared.” He closed his eyes.

“He’s making it harder.”

“Not necessarily,” Rhyme answered Lon Sellitto.

Sellitto, Banks and Sachs had just returned from the stockyard scene.

“Underwear, the moon and a plant,” cheerfully pessimistic Jerry Banks said. “That’s not exactly a road map.”

“Dirt too,” Rhyme reminded, ever appreciative of soil.

“Have any idea what they mean?” Sellitto asked.

“Not yet,” Rhyme said.

“Where’s Polling?” Sellitto muttered. “He still hasn’t answered his page.”

“Haven’t seen him,” Rhyme said.

A figure appeared in the doorway.

“As I live and breathe,” rumbled the stranger’s smooth baritone.

Rhyme nodded the lanky-man inside. He was somber-looking but his lean face suddenly cracked into a warm smile, as it tended to do at odd moments. Terry Dobyns was the sum total of the NYPD’s behavioral science department. He’d studied with the FBI behaviorists down at Quantico and had degrees in forensic science and psychology.

The psychologist loved opera and touch football and when Lincoln Rhyme had awakened in the hospital after the accident three and a half years ago Dobyns had been sitting beside him listening to Aïda on a Walkman. He’d then spent the next three hours conducting what turned out to be the first of many counseling sessions about Rhyme’s injury.

“Now what’s this I recall the textbooks sayin’ ’bout people who don’t return phone calls?”
