The Cold Moon

said he lived, the Midwest. There was also a pet hair roller.
    It’s like he’s wearing a Tyvek suit of his own. . . .
    She also found some clues that were possibly from the prior crime scenes—a roll of duct tape that would probably match the tape at the alley and that, presumably, was used to gag the victim on the pier. She found an old broom with dirt, fine sand and bits of salt on it. She guessed it was what he’d used to sweep the scene around where Teddy Adams had been killed.
    There was also evidence that she hoped might reveal his present location or that related in some way to the next victims. In a small plastic Tupperware container were some coins, three Bic pens, receipts from a parking garage downtown and a drugstore on the Upper West Side, and a book of matches (missing three of them) from a restaurant on the Upper East Side. There were no fingerprints on any of these items. She also found a pair of shoes whose treads were dotted with gaudy green paint, and an empty gallon jug that had contained wood alcohol.
    There were no fingerprints but she did find plenty of cotton fibers the same color of those in the Explorer. She then found a plastic bag containing a dozen pairs of the gloves themselves, no store labels or receipts. The bag had no prints on it.
    In his search downstairs Ron Pulaski didn’t find much but he made a curious discovery: a coating of white powder in a toilet. Tests would tell for certain but he believed it was from a fire extinguisher since he also found a trash bag near the back door, inside of which was the empty carton an extinguisherhad been sold in. The rookie had looked over the box carefully but there were no store labels to indicate where it had been purchased.
    Why the extinguisher had been discharged was unclear. There was no evidence that anything in the bathroom had been burning.
    She had a call patched through to Vincent Reynolds, in the lockup, and he told her that Duncan had recently bought a fire extinguisher. He didn’t know why it had been discharged.
    After chain-of-custody cards were filled out, Sachs and Pulaski joined Baker, Haumann and the others just inside the front door of the church, where they’d been waiting while the two officers walked the grid. Sachs called Rhyme on the radio and told him and Sellitto what they’d found.
    As she recited the evidence, she could hear Rhyme instructing Thom to include it on the charts.
    “Boston and Tampa?” the criminalist asked, referring to the museum programs. “Vincent might be wrong. Hold on.” He had Cooper check with Vital Statistics and DMV for any Gerald Duncans in those cities but, while there were residents with that name, their ages didn’t match the perp’s.
    The criminalist was silent for a moment. Then he said, “The fire extinguisher . . . I’m betting he made an incendiary device out of it. He used alcohol as the accelerant. There was some on the clock at Lucy Richter’s apartment too. That’s how he’s going to burn the next victim to death. And what’s the one thing about fire extinguishers?”
    “Give up,” Sachs replied.
    “They’re invisible. One could be sitting right next to somebody and they’d never think twice about it.”
    Baker said, “I say we take whatever clues we’ve found here and divide them up, hope one of them leads us to the next victim. We’ve got receipts, those matches, the shoes.”
    Rhyme’s voice crackled over the radio, “Whatever you do, make it fast. According to Vincent, if he’s not at the church, he’s on his way to the next victim. He might already be there by now.”
