“I watched Hanson in court carefully and I was convinced he was guilty.”

“But something went wrong?”

Dance nodded. “Witnesses couldn’t be located or their testimony fell apart, physical evidence either disappeared or was contaminated, Hanson had a series of alibis that the prosecution couldn’t shake: Every key point in the DA’s case was countered by the defense; it was as if they’d bugged the prosecutor’s office. He was acquitted.”

“That’s tough.” Rhyme looked her over. “But there’s more to the story, I sense.”

“I’m afraid there is. Two days after the trial, Hanson tracked down his wife and daughter in a shopping center parking garage and knifed them to death. The daughter’s boyfriend was with them. Hanson killed him too. He fled the area and was finally caught—a year later.”

Dance sipped her coffee. “After the murders, the prosecutor was trying to figure out what went wrong at trial. He asked me to look over the transcript of the initial interview at the sheriff’s office.” She gave a bitter laugh. “When I reviewed it I was floored. Hanson was brilliant—and the sheriff’s department deputy who interviewed him was either totally inexperienced or lazy. Hanson played him like a fish. He ended up learning enough about the prosecution’s case to completely undermine it—which witnesses to intimidate, what evidence he should dispose of, what kind of alibis he should come up with.”

“And I’m assuming he got one other bit of information,” Rhyme said, shaking his head.

“Oh, yes. The deputy asked if he’d ever been to Mill Valley. And later he asked if he ever frequented shopping centers in Marin County. That gave Hanson enough information to know where his ex and their daughter sometimes shopped. He basically just camped out around the Mill Valley mall until they showed up. That’s where he killed them—and they didn’t have any police protection there since it was a different county.

“That night I drove back home along Route One—the Pacific Coast Highway—instead of taking the One Oh One, the big freeway. I was thinking, Here I am being paid a hundred and fifty bucks an hour to anybody who needs a jury consultant. That’s all fine, nothing immoral about that—it’s the way the system works. But I couldn’t help but think that if I’d conducted that interview myself, Hanson would’ve gone to jail and three people wouldn’t have died.

“Two days later I signed up for the academy, and the rest, as they say, is history. Now, what’s the scoop with you?”

“How’d I decide to become a cop?” He shrugged. “Nothing quite so dramatic. Boring, actually . . . just kind of fell into it.”

“Really?”

Rhyme laughed.

Dance frowned.

“You don’t believe me.”

“Sorry, was I studying you? I try not to. My daughter says I look at her like she’s a lab rat sometimes.”

Rhyme sipped more scotch and said with a coy smile, “So?”

She lifted an eyebrow. “So?”

“I’m a tough nut for a kinesics expert, somebody like me. You can’t really read me, can you?”
