IT MAY BE A TOUGH SELL TO THE JURY,” Lincoln Rhyme said, speaking of the theory behind a new case against Metzger and Shales.

Amelia Sachs’s theory, not his. And one he was quite enamored of—and proud of her for formulating. Rhyme secretly loved it when people—some people—outthought him.

Sachs glanced at her humming phone. “A text.”

“Nance?”

“No.” She looked from the querying eyes of Mel Cooper to Ron Pulaski to, finally, Rhyme. “Barry Shales’s in custody. No resistance.”

So, they were proceeding now according to Sachs’s theory, which she’d come up with from a simple entry in the evidence charts.

• Victim 2: Eduardo de la Rua.
  • COD: Loss of blood. Lacerations from flying glass from gunshot, measuring 3–4mm wide, 2–3cm long.
  • Supplemental information: Journalist, interviewing Moreno. Born Puerto Rico, living in Argentina.
  • Camera, tape recorder, gold pen, notebooks missing.
  • Shoes contained fibers associated with carpet in hotel corridor, dirt from hotel entryway.
  • Clothing contained traces of breakfast: allspice and pepper sauce.

Her thinking was all the more brilliant because of its simplicity: People born in Puerto Rico are U.S. citizens.

Therefore Barry Shales had killed an American in the attack on May 9 in the South Cove Inn.

Nance’s boss, the DA, had decided not to pursue the case only because Moreno wasn’t a citizen. But de la Rua was. Even an unintended death under some circumstances can subject the killer to murder charges.

Sachs continued, “But at the very least, I’d think we could get manslaughter. Shales inadvertently killed de la Rua as part of the intentional act of killing Moreno. He should have known that someone else in the room could have been fatally wounded when he fired the shot.”

A woman’s voice filled the room. “Good analysis, Amelia. Have you ever thought of going to law school?”

Rhyme turned to see Nance Laurel striding into the parlor, lugging her briefcase and litigation bag once again. Behind her was the detective they’d asked to collect her, a friend of Sachs’s. Bill Flaherty. Rhyme had thought it safer for her to have an escort. He was still uneasy that Unsub 516 was at large, especially now that there was a chance of reviving the Moreno case.

Laurel thanked the detective, who nodded and—with a smile toward Sachs and Rhyme—left the town house.

Rhyme asked the ADA, “So? Our case? What do you think? Legally?”

“Well,” she said, sitting down at her desk and extracting her files once more, organizing them, “we probably can get Barry Shales on murder two. The penal code provision covers us there.” She paraphrased, “A person is guilty of murder in the second degree when he intends to cause the death of someone and he causes the death of a third person. But Amelia’s right, manslaughter’s definitely a possibility. We’ll make it a lesser-included offense, though I’m confident I can make murder stick.”
