The Cold Moon

"Right. Yessir. The apparent murder occurred at the far end of the pier, that is, the west end, sometime between six last night and six this morning. The dock was closed then."

There was very little evidence: just the fingernail, probably a man's, the blood, which Mel Cooper tested and found to be human and type AB positive, which meant that both A and B antigens-proteins-were present in the victim's plasma, and neither anti-A nor anti-B antigens were. In addition a separate protein, Rh, was present. The combination of AB antigens and Rh positive made the victim's the third-rarest blood type, accounting for about 3.5 percent of the population. Further tests confirmed that the victim was a male.

In addition, they concluded that he was probably older and had coronary problems since he was taking an anticoagulant-a blood thi

There were no fingerprints, trace or footprints at the scene and no tire tread marks nearby, other than those left by employees' vehicles.

Sachs had collected a piece of the chain link and Cooper examined the cut edges, learning that the perp had used what seemed to be standard wire cutters to get through the fence. The team could match these marks with those made by a tool if they found one but there was no way to trace the cutter back to its source by the impressions alone.

Rhyme looked over the pictures of the scene, particularly the pattern the blood had made as it flowed onto the pier. He guessed that the victim had been hanging over the edge of the deck, at chest level, his fingers desperately wedged into the space between the planks. The fingernail marks showed that eventually he'd lost his grip. Rhyme wondered how long the vic had been able to hang on.

He nodded slowly. "Tell me about the next scene."

Pulaski replied, "All right, that homicide occurred in an alley off Cedar Street, near Broadway. This alley featured a dead end. It was fifteen feet wide and one hundred and four feet long and was surfaced with cobblestones."

The body, Rhyme recalled, was fifteen feet from the mouth of the alley.

"What's the time of death?"

"At least eight hours before he was found, the ME tour doc said. The body was frozen solid so it'll take a while to determine with any certainty." The young officer suffered from the habit of copspeak.

"Amelia told me about the service and fire doors in the alley. Did anybody ask what time they were locked for the night?"

"Three of the buildings're commercial. Two of them lock their service doors at eight thirty and one at ten. The other's a government administration building. That door's locked at six. There's a late-night garbage pickup at ten."

"Body discovered when?"

"Around seven A.M."

"Okay, the vic in the alley was dead at least eight hours, last door was locked at ten and garbage picked up then. So the killing took place between, say, ten fifteen and eleven P.M. Parking situation?"

"I got the license plates of every car in a two-block radius." Pulaski was holding up a Moby-Dick of a notebook.

"What the hell's that?"

"Oh, I wrote down notes about all the cars. Thought it might be helpful. You know, where they were parked, anything suspicious about them."

"Waste of time. We just needed the tag numbers for names and addresses," Rhyme explained. "To cross-check DMV with NCIC and the other databases. We don't care who needed bodywork or had bald tires or a crack pipe in the backseat… Well, did you?"

"What?"

"Run the tags?"

"Not yet."

Cooper went online but found no warrants on any of the registered owners of the cars. At Rhyme's instruction he also checked to see if any parking tickets were issued in that area around the time of the killing. There were none.

"Mel, run the vic's name. Warrants? Anything else about him?"

There were no state warrants on Theodore Adams, and Pulaski recounted what his sister had said about him-that he apparently had no enemies or personal life issues that might result in his murder.

"Why these vics, though?" Rhyme asked. "Are they random?…I know Dellray's busy but this's important. Give him a call and have him run Adams's name. See if the feds have anything on him."

Sellitto made a call to the federal building and got through to Dellray-who was in a bad mood because of the "fucking quagmire" of a financial fraud case he'd been assigned. Still, he managed to look through the federal databases and active case files. But the results were negative on Theodore Adams.

"Okay," Rhyme a

A call to the bomb squad revealed that they'd been cleared of any bio or toxic threat and were on their way to Rhyme's right now.

The cash in the faux gold money clip appeared fresh out of an ATM machine. The bills were clean but Cooper found some good prints on the clip. Unfortunately, when he ran them through IAFIS, the FBI's Integrated Automated Fingerprint Identification System, there were no hits. The few prints on the cash in Adams's pocket came back negative as well, and the serial numbers revealed the bills hadn't been flagged by the Treasury Department for possible involvement in money laundering or other crimes.

"The sand?" Rhyme asked, referring to the obscuring agent.

"Generic," Cooper called, not looking up from the microscope. "Sort used in playgrounds rather than construction. I'll check it for other trace."

And no sand at the pier, Rhyme recalled Sachs telling him. Was that because, as she'd speculated, the perp was pla

"What about the span?" Rhyme asked.

"The what?"

"The bar the vic's neck was crushed with. It's a needle-eye span." Rhyme had made a study of construction materials in the city, since a popular way to dispose of bodies was to dump them at job sites. Cooper and Sellitto weighed the length of metal-it was eighty-one pounds-and got it onto the examining table. The span was about six feet long, an inch wide and three inches high. A hole was drilled in each end. "They're used mostly in shipbuilding, heavy equipment, cranes, ante

"That's gotta be the heaviest murder weapon I've ever seen," Cooper said.

"Heavier than a Suburban?" asked Lincoln Rhyme, the man for whom precision was everything. He was referring to the case of the wife who'd run over her philandering husband with a very large SUV in the middle of Third Avenue several months earlier.

"Oh, that…his cheatin' heart," Cooper sang in a squeaky tenor. Then he tested for fingerprints and found none. He filed off some shavings from the rod. "Probably iron. I see evidence of oxidation." A chemical test revealed that this was the case.

"No identifying markings?"

"Nope."

Rhyme grimaced. "That's a problem. There've got to be fifty sources in the metro area… Wait. Amelia said there was some construction nearby-"

"Oh," Pulaski said, "she had me check there and they weren't using any metal bars like that. I forgot to mention it."

"You forgot," Rhyme muttered. "Well, I know the city's doing some major work on the Queensboro Bridge. Let's give 'em a try." Rhyme said to Pulaski, "Call the work crew at the Queensboro and find out if spans're being used there and, if so, are any missing."

The rookie nodded and pulled out his mobile phone.

Cooper looked over the analysis of the sand. "Okay, got something here. Thallium sulfate."

"What's that?" Sellitto asked.

"Rodent poison," said Rhyme. "It's ba
