'I think Sparkes is in a lot of trouble, Doc,' Marino said.

'What's happened?' I wanted to know.

'Turns out that the day before the fire, Friday, he showed up at Dulles for a nine-thirty P.M. flight. He checked baggage but never picked it up at the other end, in London. Meaning it's possible he could have checked his bags and given the flight attendant the ticket at the gate, then turned right around and left the airport.'

'They do head counts on international flights,' I argued. 'His absence on the plane would have been noticed.'

'Maybe. But he didn't get where he is without being clever.'

'Marino…'

'Hold on. Let me finish giving you the rundown. What Sparkes is saying is that security was waiting for him the minute his plane landed at Heathrow at nine-forty-five the next morning - on Saturday. And we're talking England time, making it four-forty-five A.M. back here. He was told about the fire and turned right around and caught a United flight back to Washington without bothering with his bags.'

'I guess if you were upset enough, you might do that,' I said.

Marino paused, looking hard at me as I set the soap on top of the sink and dried my hands.

'Doc, you got to quit sticking up for him,' he said.

'I'm not. I'm just trying to be more objective than I think some people are being. And certainly security at Heathrow should remember notifying him when he got off that plane?'

'Not so far. And we can't quite figure out how security knew about the fire anyway. Course Sparkes has got an explanation for everything. Says security always makes special provisions when he travels and meets him at the gate. Apparently the fire had already hit the early-morning news in London, and the businessman that Sparkes was supposed to meet with called British Air to alert them to give Sparkes the news the second he was on the ground.'

'And someone's talked to this businessman?'

'Not yet. Remember, this is Sparkes's story. And I hate to tell you this, Doc, but don't think people wouldn't lie for him, either. If he's behind all this, I can guarantee that he planned it right down to the fine print. And let me also add that by the time he'd arrived at Dulles to catch the flight to London, the fire was already going and the woman was dead. Who's to say he didn't kill her and then use some kind of timer to get the fire going after he'd left the farm?'

'There's nothing to say it,' I agreed. 'There's also nothing to prove it. And there doesn't seem to be much chance of our knowing such a thing unless some material turns up in forensic exams that might point to some sort of explosive device used remotely as an igniter.'

'These days half the stuff in your house can be used as a timer. Alarm clocks, VCRs, computers, digital watches.'

'That's true. But something has to initiate low explosives, like blasting caps, sparks, a fuse, fire,' I said. 'Unless you have any other cleaning to do,' I added dryly, 'I'll be heading out.'

'Don't be pissed at me,' Marino said. 'You know, it's not like this whole damn thing is my fault.'

I stopped at his front door and looked at him. Thin gray wisps of hair clung to his sweating pate. He probably had dirty clothes flung all around his bedroom, and no one could clean and tidy up enough for him, not in a million years. I remembered Doris, his wife, and could imagine her docile servitude until the day she suddenly left and fell in love with another man.

It was as if Marino had been transfused with the wrong blood type. No matter how well his meaning or brilliant his work, he was in terrible conflict with his environment. And slowly it was killing him.

'Just do me one favor,' I said with my hand on the door.

He wiped his face on his shirt sleeve and got out his cigarettes.

'Don't encourage Lucy to jump to conclusions,' I said. 'You know as well as I do that the problem is local law enforcement, local politics. Marino, I don't believe we've even come close to what this is all about, so let's not crucify anyone just yet.'

'I'm amazed,' he said. 'After all that son of a bitch did to run you out of office. And now suddenly he's this saint?'

'I didn't say he was a saint. Frankly, I don't know any saints.'

'Sparkes-the-ladies' man,' Marino went on. 'If I didn't know better, I'd wonder if you were getting sweet on him.'

'I won't dignify that with a response.'

I walked out onto the porch, halfway tempted to slam the door in his face.

'Yeah. Same thing everyone says when they're guilty.'

He stepped out after me.

'Don't think I don't know it when you and Wesley aren't getting along…'

I turned to face him and pointed my finger like a gun.

'Not one more word,' I warned him. 'You stay out of my business, and don't you dare question my professionalism, Marino. You know better than that, goddamn it.'

I went down the front steps and got inside my car. I backed out slowly and with deliberate skill. I did not look at him as I drove off.

MONDAY MORNING WAS carried in on a storm that thrashed the city with violent winds and pelting rains. I drove to work with windshield wipers going fast and air conditioning on to defog the glass. When I opened my window to toss a token into the toll bin, my suit sleeve got drenched, and then of all days for this to happen, two funeral homes had parked inside the bay, and I had to leave my car outside. The fifteen seconds it took me to dash through the parking lot and unlock the back door of my building concluded my punishment. I was soaked. Water dripped from my hair and my shoes squished as I walked through the bay.

I checked the log in the morning office to see what had come in during the night. An infant had died in his parents' bed. An elderly woman appeared to be a suicidal overdose, and, of course, there was a drug-related shooting from one of the housing projects on the fringes of what had become a more civilized and healthy downtown. In the last several years, the city had been ranked as one of the most violent in the United States, with as many as one hundred and sixty homicides in one year for a population of less than a quarter of a million people.

Police were blamed. Even I was if the statistics compiled by my office didn't suit the politicians or if convictions were slow to come in court. The irrationality of it all never ceased to appall me, for it did not seem to occur to those in power that there is such a thing as preventive medicine, and it is, after all, the only way to halt a lethal disease. It truly is better to vaccinate against polio, for example, than to deal with it after the fact. I closed the log and walked out of the office, my shoes carrying me wetly along the empty corridor.

I turned into the locker room because I was already getting chilled. I hurried out of my sticky suit and blouse and struggled into scrubs, which were always more unwilling the more I rushed. I put on my lab coat, and dried my hair with a towel, running my fingers through it to push it out of my way. The face staring back at me in the mirror looked anxious and tired. I had been neither eating nor sleeping well, and was less disciplined with coffee and alcohol. All of it showed around my eyes. A good deal of it was due to my underlying helpless anger and fear brought about by Carrie. We had no idea where she was, but in my mind she was everywhere.

I went into the break room, where Fielding, who avoided caffeine, was making herb tea. His healthy obsessions did not make me feel any better. I had not exercised in over a week.

'Good morning, Dr Scarpetta,' he said cheerfully.

'Let's hope so,' I replied, reaching for the coffeepot. 'Looks like our caseload is fairly light so far. I'm leaving it up to you, and you can run staff conference. I've got a lot to do.'
