The Cold Moon

"Very…and there's none in the control soil and residue that Amelia collected. Which means it's probably from someplace the perp's been."

"Maybe he's pla

Rhyme shook his head. "Not likely. It's not easy to administer and you need a high dosage for humans. But it could lead us to him. Find out if there've been any recent confiscations or environmental agency complaints in the city."

Cooper made the calls.

"Let's look at the duct tape," Rhyme instructed.

The tech examined the rectangles of shiny gray tape, which had been used to bind the victim's hands and feet and gag him. He a

Disappointed that the duct tape wasn't more helpful, Rhyme turned to the photos Sachs had shot of Adams's body. Then he wheeled closer to the examination table and peered at the screen. "Look at the edges of the tape."

"Interesting," Cooper said, glancing from the digital photos to the tape itself.

What had struck the men as odd was that the pieces of tape had been cut with extreme precision and applied very carefully. Usually it was just torn off the roll, sometimes ripped by the attacker's teeth (which often left DNA-laden saliva), and wrapped sloppily around the victim's hands, ankles and mouth. But the strips used by the Watchmaker were perfectly cut with a sharp object. The lengths were identical.

Ron Pulaski hung up, then a

Well, Rhyme hadn't expected easy answers.

"And the rope he was holding on to?"

Cooper looked it over, examined some databases. He shook his head. "Generic."

Rhyme nodded at several whiteboards that stood empty in the corner of the lab. "Start our charts. You, Ron, you have good handwriting?"

"It's good enough."

"That's all we need. Write."

When ru

"We'll use his name as the heading, since he was so courteous to let us know what he wants to be called."

As Pulaski wrote what Rhyme dictated, Cooper picked up a tube containing a tiny sample of what seemed to be soil. He looked it over through the microscope, starting on 4x power (the number-one rule with optical scopes is to start low; if you go right to higher magnifications you'll end up looking at artistically interesting but forensically useless abstract images).

"Looks like your basic soil. I'll see what else's in it." He prepared a sample for the chromatograph/mass spectrometer, a large instrument that separates and identifies substances in trace evidence.

When the results were ready Cooper looked over the computer screen and a

"So maybe the perp works in a fish restaurant," Pulaski said enthusiastically. "Or a fish stand in Chinatown. Or, wait, maybe the fish counter at a grocery store."

Rhyme asked, "Ron, you ever hear a public speaker say, 'Before I begin, I'd like to say something'?"

"Uhm. I think."

"Which is a little odd, because if he's talking he's already begun, right?"

Pulaski lifted an eyebrow.

"My point is that in analyzing the evidence you do something before you start."

"Which is what?"

"Find out where the evidence came from. Now, where did Sachs collect the fish protein dirt?"

He looked at the tag. "Oh."

"Where is 'oh'?"

"Inside the victim's jacket."

"So whom does the evidence tell us something about?"

"The victim, not the perp."

"Exactly! Is it helpful to know that he has it in his jacket, not on? Who knows? Maybe it will be. But the important point is to not blindly send the troops to every fishmonger in the city too fast. You comfortable with that theory, Ron?"

"Real comfortable."

"I'm so pleased. Write down the fishy soil under the victim's profile and let's get on with it, shall we? When's the medical examiner sending us a report?"

Cooper said, "Could be a while. Coming up on Christmastime."

Sellitto sang, "'Tis the season to be killing…"

Pulaski gave a frown. Rhyme explained to him, "The deadliest times of the year are hot spells and holidays. Remember, Ron: Stress doesn't kill people; people kill people-but stress makes 'em do it."

"Got fibers here, brown," Cooper a

"What kind of fibers?"

Cooper examined them closely and ran the profile through the FBI's fiber database. "Automotive, it looks like."

"Makes sense he'd have a car-you can't really carry an eighty-one-pound iron bar around on the subway. So our Watchmaker parked in the front part of the alley and dragged the vic to his resting place. What can we tell about the vehicle?"

Not much, as it turned out. The fiber was from carpet used in more than forty models of cars, trucks and SUVs. As for tread marks, the part of the alley where he'd parked was covered with salt, which had interfered with the tires' contact with the cobblestones and prevented the transfer of tread marks.

"A big zero in the vehicle department. Well, let's look at his love note."

Cooper slipped the white sheet of paper out of a plastic envelope.

The full Cold Moon is in the sky,

shining on the corpse of earth,

signifying the hour to die

and end the journey begun at birth.

– THE WATCHMAKER

"Is it?" Rhyme asked.

"Is it what?" Pulaski asked, as if he'd missed something.

"The full moon. Obviously. Today."

Pulaski flipped through Rhyme's New York Times. "Yep. Full."

"What's he mean by the Cold Moon in caps?" De

Cooper did some searching on the Internet. "Okay, it's a month in the lunar calendar… We use the solar calendar, three hundred and sixty-five days a year, based on the sun. The lunar calendar marks time from new moon to new moon. The names of the months describe the cycle of our lives from birth to death. They're named according to milestones in the year: the Strawberry Moon in the spring, the Harvest Moon and Hunter Moon in the fall. The Cold Moon is in December, the month of hibernation and death."

As Rhyme had noted earlier, killers referencing the moon or astrological themes tended to be serial perps. There was some literature suggesting that people were actually motivated by the moon to commit crimes but Rhyme believed that was simply the influence of suggestion-like the increase in alien abduction reports just after Steven Spielberg's film Close Encounters of the Third Kind was released.

"Run the name Watchmaker through the databases, along with 'Cold Moon.' Oh, and the other lunar months too."

After ten minutes of searching through the FBI's Violent Criminal Apprehension Program and the National Crime Information Center, as well as state databases, they had no hits.

Rhyme asked Cooper to find out where the poem itself had come from but he found nothing even close in dozens of poetry websites. The tech also called a professor of literature at New York University, a man who helped them on occasion. He'd never heard of it. And the poem was either too obscure to turn up in a search engine or more likely it was the Watchmaker's own creation.
