"What happened?"

"Fire," he said. "Place went up like a fucking film warehouse. Meserole Street? Couple of blocks from Bushwick Terminal? Isn't that where you said it was?"

"That's right."

"You don't recall the street number, by any chance?"

I was reaching for my notebook when T J said, "One sixty-eight."

"That's some memory, Tom Jones."

"He was out there," I said.

"When was this?"

"Few days ago," T J said. "Met all but one of them. They showed me what they doin', the renovations an' all."

"They just gave you the grand tour?"

"They under the 'pression I from the Buildings Department," he said. "They was doin' a whole lot of work on that house."

"That's nothing," Wentworth said. "You're not gonna recognize the place."

It had taken them a while to get the fire under control, but it was out by the time we got there, and the last hook-and-ladder unit was just pulling away as Wentworth angled in next to a red NYFD inspector's car.

I saw, but barely registered, the crowds of onlookers, the booted firemen walking around, the house itself with its windows gone and great holes chopped in its roof. We walked in, escorted by a fire inspector and a cop from the local precinct. Crime lab personnel were on the scene, along with someone from the medical examiner's office.

We climbed stairs to the top floor and worked our way down. Most of the internal walls had been removed in the renovation, so we didn't have to go room to room; each floor was just one large room, and each room held its dead.

On the top floor, a large man lay on his side, one arm under his body, the other flung out to the side. He'd been pretty thoroughly roasted in the fire, and there wasn't enough of his face left to offer a clue of what he looked like.

"Stabbed twice, maybe more," somebody said. "They were all stabbed, though it's easier to tell with some of them than with the others. There's empty drums of muriatic acid all over the place. You use it to get plaster residue off brick, and it looks as though he sloshed it over their faces. But we won't know for a while how much damage the acid did and how much was the fire, because everybody got a second dousing with accelerant before the place went up."

T J said the dead man was Peter Meredith, basing his identification on the corpse's girth. One floor down we found two more bodies, killed the same way, disfigured and burned the same way. T J was less certain, but guessed we were looking at all that was left of Marsha Kittredge and Lucian Bemis. They lay side by side, with the smaller figure nestled in the crook of the larger one's arm.

The fire had been a little less intense on the first floor, at least at the front of the house where the two bodies lay. The man's hands and face had been bathed in muriatic acid, and his hair and most of his clothing had been burned away, but it was easy to spot the stab wounds in his chest.

"Kieran Eklund," T J said. "Never did meet him, but that there's Ruth Ann Lipinsky. Just about enough left of her to recognize."

She lay a few feet away, her face eroded by the acid, her hair burned away in the fire, her throat slashed. Blood had gouted from the wound and pooled around her, and big bloody footprints, still distinguishable after the fire, led diagonally across the floor to a stairway at the rear.

"He went out the back," I said, but the fire inspector shook his head.

"He didn't go anywhere," he said.

The stairs down to the basement had mostly burned away. A portable metal ladder, marked FDNY, had been laid down over what remained of it, and we made our way down it one at a time. The cellar floor was a couple of inches deep in water, among other things.

There was a pile of rags at the foot of the stairs. Except it wasn't a pile of rags.

"Crispiest critter of them all," the fire inspector said, nudging the corpse with a booted foot. "That's a hunting knife next to him, and what do you bet it's the one made those cuts upstairs? I'd say the odds are good. You want to know what happened?"

"I'd love to know what happened," Wentworth said.

"I can tell you how we reconstruct it, based on preliminary observations. It's all subject to change when we've reached the stage where we're ready to release a full report."

"Understood."

"He went floor by floor, starting at the top. Killed the guy on the top floor, came down a flight, did the man and woman, one more flight and killed the last couple. Though how he managed to do all that without anybody resisting is something I'm glad it's not my job to figure out."

"They were patients of his," I said. "He was somewhere between a father figure and a cult leader."

"Maybe they drank Kool-Aid first," Wentworth said.

"Whatever," the fire inspector said. "He killed the last one and went upstairs again and did what he did with the muriatic acid, and then poured accelerant over the bodies and elsewhere on the various floors. It looks as though he had all kinds of accelerants to choose from and it looks as though he used them all. Paint thinner, turpentine, joint compound, different kinds of solvents. They were artists, and between their art supplies and what they were using for renovation, they had enough accelerant to burn down Mount Everest. Worked his way down killing, worked his way down a second time with the acid and the accelerant.

"Time he got down here he was running low on accelerant, or maybe it was beginning to dawn on him that he better move his ass before the place went up like a torch. So he went a little light on the accelerant, and he stepped in the blood, and tracked it across the floor."

"Sloppy," somebody said.

"Down here," the inspector went on, "is what he was saving the rest of the accelerant for, and his instincts were good, because fire burns up, not down. He splashed shit all over the place, and then he did something you never want to do when you're fixing to burn your house down."

"Lit a cigarette?"

"Well, he could have, if he was dumber than shit. If he was not quite that stupid, my guess is he decided he needed a little more light, and he flicked that switch right over there. You flick a light switch, you're apt to get a little bit of a spark. You never see it and it doesn't amount to anything, unless you happen to be in a room full of volatile fumes, which he was. Boom- instant explosion, instant wall of flame, and we can only hope he knows better next time."

"Fucking electricity," someone said. "He shoulda used a candle."

"If only," the inspector said. "One other possibility, before you all clear out of here and go home to the dinners you've no longer got any stomach for. It's just as possible he knew what he was doing. If he figured it was all up and he wanted to join his fellow cult members in the next world, well, this way he'd go fast. It might not be much fun while it lasted, but it wouldn't last very long. Any questions, gentlemen?"

Wentworth said, "Anybody got a flashlight?" And, when one was handed to him, "Is it all right to turn this on? Is it safe?"

"I don't think you get a spark from a flashlight," the inspector said. "And you may not have noticed it, but they already had their fire here."

"Looks like something on that wall," Wentworth said, and flicked on the flashlight.

"I noticed that before," the inspector said. "I thought it was blood at first, but it looks like he used red paint."

" 'I came like water and like wind I go. Audrey Beardsley.' Who in the hell is Audrey Beardsley?"

"I think it's Aubrey Beardsley."

"Is that a B? All right, maybe it is. Same question. Who the hell is Aubrey Beardsley?"

"An illustrator," I said. "Around the turn of the century. And he didn't write those lines. They're from the The Rubáiyát of Omar Khayyám."

"Maybe Beardsley was easier to spell," someone suggested.
