460 and stopped for milk, Hershey's syrup, fresh vegetables and soup.

I charged up and down aisles, and next thing I knew my cart was full of everything from toilet paper to deli meats. Then I got out a map and the address Pleasants had given to me. His mother was not too far off the main route, and when I arrived she was asleep.

'Oh dear,' I said from the porch. 'I didn't mean to get you up.'

'Who is it?' She peered blindly into the night as she unhooked the door.

'Dr Kay Scarpetta. You have no reason…'

' What kind of doctor?'

Mrs Pleasants was wizened and stooped, her face wrinkled like crepe paper. Long gray hair floated like gossamer, and I thought of the landfill and the old woman deadoc had killed.

'You can come on in.' She shoved open the door and looked frightened. 'Is Keith all right? Nothing happened to him, did it?'

'I saw him earlier, and he's fine,' I assured her. 'I brought groceries.' I had the bags in my hands.

'That boy.' She shook her head, motioning me into her small, tidy home. 'What would I do? You know, he's all I've got in this world. When he was born I said, "Keith, it's just you."'

She was scared and upset and didn't want me to know.

'Do you know where he is?' I gently said.

We entered her kitchen with its old, squat refrigerator and gas stove, and she did not answer me. She started putting groceries away, fumbling with cans and dropping celery and carrots to the floor.

'Here. Let me help,' I tried.

'He didn't do anything wrong.' She began to cry. 'I know he didn't. And that policeman won't leave him be, always coming over, banging on the door.'

She stood in the middle of her kitchen, wiping her face with her hands.

'Keith says you like chocolate milk, and I'm going to make you one. It's just what the doctor ordered.'

I fetched a glass and a spoon from the drain board.

'He'll be home tomorrow,' I said. 'And I don't imagine you'll be hearing from

Investigator Ring anymore.'

She stared at me as if I were a miracle.

'I just wanted to make sure you have everything you need until your son gets here,' I

said, handing her the glass of chocolate milk mixed medium dark.

'I'm just trying to figure out who you are,' she finally said. 'This is mighty good. Nothing in life any better.' She sipped and smiled and took her time.

I briefly explained how I knew Keith and what I did professionally, but she did not understand. She assumed I was sweet on him and issued medical licenses for a living. On my way home, I played CDs loudly to keep me awake as I drove through thick darkness, where for long stretches there was not a single light except stars. I reached for the phone.

Wingo's mother answered and told me he was sick in bed. But she got him on the line.

'Wingo, I'm worried about you,' I said with feeling.

'I feel terrible.' He sounded like it. 'I guess you can't do anything for the flu.'

'You're immunosuppressed. When I talked to Dr Riley last, your CD4 cell count was not good.' I wanted him to face reality. 'Describe your symptoms to me.'

'My head's killing me, my neck and back are killing me. Last time my temperature was taken it was a hundred and four. I'm so thirsty all the time.'

Everything he said was setting off alarms in my head, for the symptoms also described the early stages of smallpox. But if his exposure was the torso, I was surprised he hadn't gotten sick before now, especially in light of his compromised condition.

'You haven't touched one of those sprays we got at the office,' I said.

'What sprays?'

'The Vita facial sprays.'

He was clueless, and then I remembered that he was out of the office much of today. I

explained what had happened.

'Oh my God,' he said suddenly, as fear shot through both of us. 'One came in the mail. Mom had it on the kitchen counter.'

'When?' I said in alarm.

'I don't know. A few days ago. When was that? I don't know. We' d never seen anything so fancy. Imagine, something sweet to cool your face.'

That made twelve canisters deadoc had delivered to my staff, and twelve had been his message to me. It was the number of full-time people in my central office, if I included myself. How could he know such trivia as the size of my staff, and even some of their names and where they lived, if he were far away and anonymous?

I dreaded my next question because I already thought I knew. 'Wingo, did you touch it in any way?'

'I tried it. Just to see.' His voice was shaking badly and he was choking from coughing fits. 'When it was sitting there. I picked it up one time, just to see. It smelled like roses.'

'Who else in your house has tried it?'

'I don't know.'

'I want you to make certain no one touches that canister. Do you understand?'

'Yes.' He was sobbing.

'I'm going to send some people to your house to pick it up and take care of you and your family, okay?'

He was crying too hard to answer.

When I got home, it was minutes past midnight, and I was so out of sorts and sick that I did not know what to do first. I called Marino and Wesley, and Fujitsubo. I told everybody what was happening and that Wingo and his family needed a team at their home immediately. My bad news was returned by theirs. The girl on Tangier who had gotten sick had died, and now a fisherman had the disease. Depressed and feeling like hell, I checked my e-mail, and deadoc was there in his small, mean way. I was glad. His message had been sent while Keith Pleasants was in jail.

mirror mirror on the wall where have you been

'You bastard,' I screamed at him.

The day was too much. All of it was too much, and I was achy and woozy and completely fed up. So I should not have gone into that chat room, where I waited for him as if this were the O.K. Corral. I should have left it for another time. But I made my presence known and paced in my mind as I waited for the monster to appear. He did.

DEADOC: toil and trouble SCARPETTA: What do you want? DEADOC: we are angry tonight SCARPETTA: Yes, we are.

DEADOC: why should you care about ignorant fishermen and their ignorant families and those inept people who work for you

SCARPETTA: Stop it. Tell me what you want to make this stop. DEADOC: it s too late the damage is done it was done long before this SCARPETTA: What was done to you?

But he did not answer. Oddly, he did not leave the room, but he did not respond to any further questions from me. I thought of Squad 19 and prayed they were listening and following from trunk to trunk, tracing him to his lair. Half an hour passed. I finally logged off as my telephone rang.

'You're a genius!' Lucy was so excited she was hurting my ears. 'How the hell have you managed to keep him on that long?'

'What do you mean?' I asked, amazed. 'Eleven minutes so far. You win the prize.'

'I was only on with him maybe two minutes.' I tried to cool my forehead with the back of my hand. 'I don't know what you're talking about.'

But she didn't care. 'We nailed the son of a bitch!' She was ecstatic. 'A campground in

Maryland, agents from Salisbury already en route. Janet and I gotta plane to catch.' Before I got up the next morning, the World Health Organization put out another international alert about Vita aromatic facial spray. WHO reassured people that this virus would be eliminated, that we were working on the vaccine around the clock and would have it soon. But the panic began anyway.

The virus, dubbed by the press Mutantpox, was on the cover of Newsweek and Time, and the Senate was forming a subcommittee as the White House contemplated emergency measures. Vita was distributed in New York, but the manufacturer was actually French. The obvious concern was that deadoc was making good on his threat. Although there were yet no reports of the disease in France, economic and diplomatic
