“That I can explain. Nemerov’s family wanted it kept quiet, and we obliged. They didn’t want Boris’s lapse in judgment made public—bad for business. And they had quite a few favors to pull in—reporters’ kids who’d been bailed out. Cops’ kids, too. Del and I were ordered to do our job but to do it very quietly.”

“Did that hamstring you?”

“Not really. Finding Burns wasn’t going to be accomplished by feeding the press. The Nemerovs were decent folk—first everything they’d gone through in Russia and now this. We didn’t want to upset them, everyone felt bad about the whole thing. The business almost went under, anyway. The insurance companies weren’t pleased, wanted to sever all ties. Nemerov’s widow and son agreed to eat all fifty grand of Burns’s forfeited bail and begged for a chance to prove themselves. They managed to hold on to most of their policies. Eventually, they got their heads above water. They’re still in business—same place, right around the corner from the station. Nowadays they’re known for never giving an inch.”

“And Willie Burns’s trail went cold,” I said.

“I dogged him for years, Alex. Anytime I had a lull, I checked on the asshole. I was sure he’d turn up eventually because a junkie’s unlikely to change his ways. My bet was he’d end up incarcerated or dead.”

“Maybe he did end up dead,” I said. “The Nemerov family had access to professional searchers. Even good folk can develop a thirst for revenge.”

“My gut says no, but if that’s what happened, it’s a definite dead end. I’m starting to feel like I’m back in junior high, staring at tests I flunked.”

“Maybe it’s only one big test,” I said. “Maybe Willie Burns knew Caroline before she was sent to Achievement House—one of the black guys Dr. Schwartzman saw Caroline hanging with. Burns’s murdering Nemerov could’ve been nothing new for him, because he’d killed before. At a party in Bel Air.”

“Burns’s record was nonviolent, Alex.”

“Till it wasn’t,” I said. “What if the nonviolent crimes were the ones he never got caught for. Was he only into heroin?”

“No, poly-drug addict. Heroin, acid, pills, meth. Since the age of ten.”

“Ups and downs,” I said. “Unpredictable behavior. Put someone like that in contact with an unbalanced kid like Caroline, stick both of them at a dope party where two not-too-bright street girls show up, and who knows what might happen? Caroline’s family suspected—or knew she’d been part of something bad and sent her to Achievement House. Willie split back to the streets but found his way over to Achievement House to visit Caroline. Stupid move, but junkies are impulsive. And no one caught on. He worked there for a month, was fired because of absenteeism.”
