So, who could the presentations be aimed at? The police? The forensics wonks? Me? None of those were likely, and beyond those and the three or four people who had discovered the bodies, nobody had seen anything, and there had been only the tremendous outcry from the entire state of Florida, desperate to save the tourist industry.

A thought snapped my eyes open, and there was Deborah staring at me like an Irish setter on point.

“What, goddamn it?” she said.

“What if this is what they want?” I said.

She stared at me for a moment, looking quite a bit like Cody and Astor when they've just woken up. “What's that mean?” she finally said.

“The first thing I thought about the bodies was that it wasn't about killing them. It was about playing with them afterwards. Displaying them.”

Debs snorted. “I remember. It still doesn't make any sense.”

“But it does” I said. “If somebody is trying to create an effect. To have an impact in some way. So look at it backwards —what impact has this already had?”

“Aside from getting media attention all over the world—”

“No, not aside from that. That is exactly what I mean.” She shook her head. “What?”

“What's wrong with media attention, sis? The whole world is looking at the Sunshine State —at Miami, tourist beacon to the world.”

“They're looking, and they're saying no fucking way am I going anywhere near that slaughter house” Deb said. “Come on, Dex, what's the fucking point? I told you —oh.” She frowned. “You're saying somebody did this to attack the tourist industry? The whole fucking state? That's fucking nuts.”

“You think somebody did this who isn't nuts, sis?”

“But who the hell would do that?” I don't know” I said. “California?”

“Come on, Dexter” she snarled. “It has to make sense. If somebody does this, they have to have some kind of motive.”

“Somebody with a grudge” I said, sounding a lot more certain than I felt.

“A grudge against the whole fucking state?” she said. “Is that supposed to make sense?”

“Well, not really” I said.

“Then how about if you come up with something that does make sense? And, like, right now? Because I don't see how this could get much worse.”

If life teaches us anything, it is to flinch away and roll under the furniture whenever anyone is foolish enough to utter those fell words. And sure enough, the dreadful syllables were barely out of Deborah's mouth when the phone on her desk buzzed for her attention, and some small and rather nasty voice whispered in my ear that this would be a great time to wedge myself under the desk in the foetal position.

Deborah snatched up the phone, still glaring at me, and then suddenly turned away and hunched over. She muttered a few shocked syllables that sounded like, “When? Jesus. Right” and then she hung up and turned a look on me that made her previous glare seem like the first kiss of springtime. “You motherfucker” she said.

“What did I do?” I said, rather surprised by the cold fury in her voice.

“That's what I want to know” she said.

Even a monster reaches a point where irritation begins to trickle in, and I believe I was very close to that point. “Deborah, either you start speaking complete sentences that actually make sense, or I'm going back to the lab to polish the spectrometer.”

“There's a break in the case” she said.

“Then why aren't we happy?”

“It's at the Tourist Board” she said.

I opened my mouth to say something witty and cutting, and then I closed it again.

“Yeah” Deborah said. “Almost like somebody had a grudge against the whole state.”

“And you think it's me?” I said, beyond irritation now and all the way to open-mouthed astonishment. She just stared at me. “Debs, I think somebody put lead in your coffee. Florida is my home —you want me to sing “Swanee River?” It might not have been the offer to sing that animated her, but whatever it was she looked at me for another long moment and then jumped up. “Come on, let's get over there” she said.

The? What about Coulter, your partner?”

“He's getting coffee, fuck him,” she said. “Besides, I'd rather partner with a warthog. Come on.” For some reason I did not actually swell with pride at being slightly better than a warthog, but when duty calls, Dexter answers, and I followed her out the door.

The Greater Miami Convention and Visitor's Bureau was in a high-rise building on Brickell Avenue, as befitted its status as a very important organization.

The full majesty of its purpose was reflected in the view from its windows, which showed a lovely slice of downtown and Government Cut, a swathe of Biscayne Bay, and even the nearby Arena where the basketball team shows up from time to time for some really dramatic losses.

It was a wonderful view, almost a postcard, as if to say, “Look —this is Miami: we weren't kidding.” Very few of the Bureau's employees seemed to be enjoying the view today, however. The office resembled a giant oak-lined bee's nest that somebody had poked with a stick. There could not have been more than a handful of employees, but they were flitting in and out of doors and up and down the hallway so rapidly it looked like there were hundreds of them in constant motion, like crazed particles in a whirring jar of oil.

Deborah stood at the receptionist's desk for two full minutes —a lifetime as far as her sense of patience was concerned —before a large woman paused and stared at her.

“What do you want?” the woman demanded.

Debs immediately flashed her badge. “I'm Sergeant Morgan. From the police?”

“Oh my God” the woman said. “I'll get Jo Anne” and disappeared through a door on the right. Deborah looked at me as if it was my fault and said, “Jesus” and then the door slammed open again and a small woman with a long nose and a short haircut came barreling out.

“Police?” she said with real outrage in her voice. She looked beyond us and then back to Deborah. “You're the police? What, the pin-up police?”

Of course, Deborah was used to having people challenge her, but usually not quite so brutally. She actually blushed a little before she held up her badge again and said, “Sergeant Morgan. Do you have some information for us?”

“This is no time for being politically correct” the woman said. I need Dirty Harry, and they send Legally Blonde.” Deborah's eyes narrowed and the pretty red flush left her cheeks.

“If you'd like, I can come back with a subpoena” she said. “And possibly a warrant for obstructing an investigation.” The woman just stared. Then there was a yell from the back room and something large fell over and broke. She jumped a little, then said, “My God. All right, come on” and she vanished through the door again. Deborah breathed out hard, showing a few teeth, and then we followed.

The small woman was already disappearing through a door at the end of the hall, and by the time we caught up with her she was settling into a swivel chair at a conference table. “Sit down” she said, waving at the other chairs with a large black remote control. Without waiting to see if we sat, she pointed the remote at a big flat-screen TV and said, “This came yesterday, but we didn't get around to looking at it until this morning.”

She glanced up at us. “We called right away” she said, perhaps still trembling with fear from Deborah's threat of a warrant. If so, she was controlling her trembles remarkably well.

“What is it?” Deborah said, sliding into a chair. I sat in one next to her as the woman said, “The DVD. Watch.” The TV blinked into life, went through a few wonderfully informative screens asking us to wait or select, and then blurted into life with a high-pitched scream. Beside me, Deborah jumped involuntarily.

The screen lit up and an image jumped into focus: from an unmoving position above, we saw a body lying against a white porcelain background. The eyes were wide and staring and, to someone of my modest experience, obviously dead. Then a figure moved into view and partially blocked the body. We saw only the back, and then the upraised arm holding a power saw. The arm went down and we heard the whine of the blade biting into flesh.
