"If he has, it's the first time he's gone public. I called VICAP, nothing in their files matches. The agent I spoke to said it had elements of both organized and disorganized serials, thank you very much."

"You said the amputation was clumsy," I said.

"That's the coroner's opinion."

"So maybe our boy's got some medical aspirations. Someone with a grudge, like a med-school reject, wanting to show the world how clever he is."

"Maybe," he said. "Then again, Mate was a legit doc and he was no master craftsman. Last year he removed a liver from one of his travelers, dropped it off at County Hospital. Packed with ice, in a picnic cooler. Not that anyone would've accepted it, given the source, but the liver was garbage. Mate took it out all wrong, hacked-up blood vessels, made a mess."

"Doctors who don't do surgery often forget the little they learned in med school," I said. "Mate spent most of his professional life as a bureaucrat, bouncing from public health department to public health department. When did this liver thing happen? Never heard about it."

"Last December. You never heard about it because it was never made public. 'Cause who'd want it to get out? Not Mate, because he looked like a clown, but not the D.A.'s office, either. They'd given up on prosecuting Mate, were sick of giving him free publicity. I found out because the coroner doing the post on Mate had seen the paperwork on the disposal of the liver, had heard people talking about it at the morgue."

"Maybe I wasn't giving the killer enough credit," I said. "Given the tight space, darkness, the time pressure, it couldn't have been easy. Perhaps those error wounds weren't the only time he slipped. If he nicked himself he could've left behind some of his own biochemistry."

"From your mouth to God's ears. The lab rats have been going over every square inch of that van, but so far the only blood they've been able to pull up is Mate's. O positive."

"The only common thing about him." I was thinking of the one time I'd seen Eldon Mate on TV. Because I had followed his career, had watched a press conference after a "voyage." The death doctor had left the stiffening corpse of a woman— almost all of them were women— in a motel near downtown, then showed up at the D.A.'s office to "inform the authorities." My take: to brag. The man had looked jubilant. That's when a reporter had brought up the use of budget lodgings. Mate had turned livid and spat back the line about Jesus.

Despite the public taunt, the D.A. had done nothing about the death, because five acquittals had shown that bringing Mate up on charges was a certain loser. Mate's triumphalism had grated. He'd gloated like a spoiled child.
