The Stone Monkey

She made another call to the criminalist.

"Go ahead," Rhyme said grimly. How it hurt to hear the pain in his voice. For years she'd heard so much flat emotion, so much lethargy, so much resignation. That had been tough but it didn't compare to the pain now in Rhyme's voice.

"He was shot three times in the chest but we've got four casings. One casing's from a Model 51, probably the one we saw before. The others are.45. He was killed with that one, it looks like. Then I found the Walther that So

"What's your scenario, Sachs?"

"I think So

"Because," Rhyme said, "the yellow paper and the plant material were on So

"That's what it looks like."

"And how do we use that scenario?"

"Wherever the Ghost bought that stuff that was in the bag, a clerk might know him and have an idea where he lives."

"You want to canvass all the stores near there to see who has yellow bags?"

"No, that'd take too long. It'd be better to find out what the plant material is first."

"Bring it in, Sachs. Mel'll run it through the chromatograph."

"No, I've got a better idea," she said. A glance at So

To effect capture… the opponent's men must be entirely encircled without any adjacent places vacant… Exactly as in war, when a post is surrounded, the soldiers are taken prisoner by the enemy.

Chapter Forty-one

He stared out the window at the gray dusk, premature because of the lingering storm. His head drooped forward, heavy, heavy, immobile. This wasn't from damaged fibers of nerve but from sorrow. Rhyme was thinking of So

When he'd run the forensic unit he'd had the chance to hire dozens, probably hundreds of employees and to finagle – or bully – onto his staff men and women from other assignments because he knew they were damn good cops. He couldn't tell exactly what appealed to him about these people. Oh, sure, they had the textbook qualifications: persistence, intelligence, patience, stamina, keen powers of observation, empathy.

Yet there was another quality. Something that Rhyme, for all his rational self, couldn't define, though he recognized it immediately. There was no better way to say it than the desire – even the joy – of pursuing a prey at all costs. Whatever else So

He glanced at the book he'd inscribed to Li.

To my friend…

"Okay, Mel," he said evenly. "Let's put this one together. What've we got?"

Mel Cooper was hunched over the plastic bags the patrolman had raced here from the crime scene in Chinatown. "Footprints."

"We sure it was the Ghost?" Rhyme asked.

"Yep," Cooper confirmed. "They're identical." Looking at the electrostatic prints that Sachs had taken.

Rhyme agreed they were the same.

"Now the slugs." He was examining the two bullets, one flattened, one intact, both bloody. "Check the lands and grooves."

This referred to the angular marks left in the soft lead bullet by the rifling in the barrel of the gun – the spiral grooves that spin the slug to make it go faster and more accurately. By examining the number of grooves and the degree of the twist, a ballistics expert can often determine the type of gun the shooter used.

Cooper, wearing latex gloves, measured the undamaged slug and the marks cut in the side from the rifling. "It's a forty-five ACP. Octagonal profile on the lands and grooves, right-hand twist. I'm guessing one complete twist every fifteen, sixteen inches. I'll look that up and -"

"Don't bother," Rhyme said shortly. "It's a Glock." The unsexy but dependable Austrian pistols were increasingly popular throughout the world, among criminals and police alike. "What's the wear on the barrel?"

"Sharp profile."

"So it's new. Probably the G36." He was surprised. This compact but extremely powerful handgun was expensive and wasn't widely available yet. In the United States you found it mostly among federal agents.

Useful, useful? he wondered.

Not yet. All it told them was the type of gun, not where the weapon or the ammunition had been purchased. Still, it was evidence and it belonged on the board.

"Thom… Thom!" Rhyme shouted. "We need you!"

The aide appeared immediately. "There're other things I need -"

"No," Rhyme said. "There aren't other things. Write."

The aide must have sensed Rhyme's despondency over the death of So

Cooper then opened Li's clothes over a large sheet of clean, blank newsprint. He dusted the items of clothing with a brush and examined the trace that had fallen onto the paper. "Dirt, flecks of paint, the yellow paper particles that probably were from the bag and the dried plant material – spices or herbs – that Amelia mentioned," Cooper said.

"She's checking out the plant stuff right now. Just bag them and put them aside for the time being." Rhyme, who over the years had grown immune to the horror of crime scenes, nonetheless felt a pang as he looked at the dark blood on Li's clothing. The same clothing he'd worn in this very room not long ago.

Zaijian, So

"Fingernail scrapings," Cooper a

"Project it, Mel," Rhyme said and turned to the computer screen. A moment later a clear image appeared on the large flat screen. What do we have here, So

And if so, will it send us to his front door?

"Tobacco," the criminalist said, laughing sadly, thinking of the cop's addiction to cigarettes. "What else do we see? What are those minerals there? What do you think, Mel? Silicates?"

"Looks like it. Let's run some through the GC/MS."
