ome frequency.

He announced, "I'll say it's likely that the same person was at both scenes. But remember, Person A could have been at the first site, smoking a Marlboro. Person B could have bummed one off him and set up the trap at the Mountain View Motel. Not likely but it could be. How long for the DNA?"

"Another few days."

A grimace. "But it's not any better in New York, of course. I don't think you'll find any, though. Your perp is smart. He probably lit it by blowing on the tip, not holding it in his lips. So, does this Edwin Sharp smoke?"

"He used to," Dance said. "Still may sometimes but we don't know."

They couldn't draw any conclusions from the boot print--really just the toe. Sachs studied the electrostatic print. "Agree that it's probably a cowboy boot. Pretty common in New York a few years ago--line dancing was all the rage." She added that Rhyme had compiled a footwear database but the electrostatic image was too fuzzy to give them a brand name.

"All right, the fishing line ... nothing there, I'm afraid. 'Generic' is a word I dislike very much. Let's look at the shell casings."

Shean reiterated that he thought the gun at both the Blanton shooting and the Sheri Towne attack was probably the same.

"You can say 'match,'" Rhyme said. "Won't bite you, in this context. But where did the gun come from? Stolen from one of your officers, you were saying?"

"Possibly--Gabriel Fuentes. He's been suspended."

"I heard."

"I wish we could tell. It might help incriminate Sharp. He was near Gabe's car when the gun was stolen. But we don't know for sure."

"No? Let me have the close-ups of the extractor marks and scratches," Rhyme said. "And the ones of the lands and grooves on the slugs."

Shean placed them on a table for Rhyme to examine. "But we don't have known samples from Gabe's Glock. I asked him and--"

"I know you don't."

"Oh, right, otherwise we would have identified the gun."

"Exactly." Rhyme's brow furrowed as he examined the pictures. "Sachs?"

Dance recalled that though they were both romantic and professional partners, they tended to refer to each other by their last names. Which she found rather charming.

Sachs studied the pictures too. Apparently she knew exactly what he was interested in. "I'd say four thousand."

"Good," Rhyme announced. Then: "I need the serial number of Fuentes's gun."

A fast computer search revealed it. Rhyme glanced at the number. "Okay, the gun was made four years ago by our talented friends in Austria. Call this Fuentes and ask him when he got it and how often he fired it."

Harutyun made this call. He jotted notes and looked up. "You need anything else from Gabriel, Lincoln?"

"No. Not now. Maybe later. Don't let him wander too far from his mobile."

The answer was that he'd bought the weapon new--three years ago--and took it to the range twice a month or so. He would typically fire fifty rounds.

Rhyme gazed into the air over the local officers. "Fifty rounds, every two weeks, for three years means it's been fired about thirty-nine hundred times. From the pictures of the shells and the slugs, Sachs estimated they came from a gun that had been fired about four thousand times. Good eye." He glanced at her.

Sachs explained to the others, "The distension of the brass, cracks around the neck and the spread of the lands and grooves are typical of a gun fired with that frequency."

Shean was nodding as if memorizing this. "So it is Gabe's weapon."

"Most likely," Sachs said.

Rhyme called, "Microscope! Charlie, I need a 'scope."

"Well, the scanning electron--"
