“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?” Dennis Baker asked.

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.

Cooper said, “As for the note itself, it’s generic paper from a computer printer. Hewlett-Packard LaserJet ink, nothing distinctive.”

Rhyme shook his head, frustrated at the absence of leads. If the Watchmaker was in fact a cyclical killer he could be somewhere right now, checking out—or even murdering—his next victim.

A moment later Amelia Sachs arrived, pulled off her jacket. She was introduced to Dennis Baker, who told her he was glad she was on the case; her reputation preceded her, the wedding-ring-free cop added, smiling a bit of flirt her way. Sachs responded with a brisk, professional handshake. All in a day’s work for a woman on the force.

Rhyme briefed her on what they’d learned from the evidence so far.

“Not much,” she muttered. “He’s good.”

“What’s the story on the suspect?” Baker asked.
