'Let's see. No, it doesn't say what was purchased.

I'm sorry.' He sounded more disappointed than I was.

'And the other charge?'

'To USAir. A plane ticket for five hundred and fourteen dollars. This was round trip from La Guardia to Richmond.'

'Do we have dates?'

'Only of the transaction. You'd have to get the actual departure and return dates from the airline. Here's the ticket number.'

I asked him to contact me immediately if further charges showed up on the bank's computer. Glancing up at the clock, I flipped through the telephone directory. When I dialed the number of the gallery, the phone rang a long time before I gave up.

Then I tried USAir and gave them the ticket number Brent had given me. Gault, using my American Express card, had flown out of La Guardia at 7:00 a.m. on Friday, December 22. He had returned on the 6:50 flight that night. I was dumbfounded. He was in Richmond an entire day. What did he do during that time besides visit an art gallery?

'I'll be damned,' I muttered as I thought about New York laws.

I wondered if Gault had come here to buy a gun, and I called the airline again.

'Excuse me,' I said, identifying myself one more time. 'Is this Rita?'

'Yes.'

'We just spoke. This is Dr. Scarpetta.'

'Yes, ma'am. What can I do for you?'

'The ticket we were just discussing. Can you tell if bags were checked?'

'Please hold on.' Keys rapidly clicked. 'Yes, ma'am. On the return flight to La Guardia one bag was checked.'

'But not on the original flight out of La Guardia.'

'No. No bags were checked on the La Guardia to Richmond leg of the trip.'

Gault had served time in a penitentiary that once was located in this city. There was no telling who he knew, but I was certain if he wanted to buy a Glock nine-millimeter pistol in Richmond, he could. Criminals in New York commonly came here for guns. Gault may have placed the Glock in the bag he checked and the next night he shot Jane.

What this suggested was premeditation, and that had never been part of the equation. All of us had supposed Jane was someone Gault chanced upon and decided to murder, much as he had his other victims.

I made myself a mug of hot tea and tried to calm down. It was only the middle of the afternoon in Seattle, and I pulled my National Academy of Medical Examiners directory off a shelf. I flipped through it and found the name and number of Seattle's chief.

'Dr. Menendez? It's Dr. Kay Scarpetta in Richmond,' I said when I got him on the phone.

'Oh,' he said, surprised. 'How are you? Merry Christmas.'

'Thank you. I'm sorry to bother you, but I need your help.'

He hesitated. 'Is everything all right? You sound very stressed.'

'I have a very difficult situation. A serial killer who is out of control.' I took a deep breath. 'One of the cases involves an unidentified young woman with a lot of gold foil restorations.'

'That's most curious,' he said thoughtfully. 'You know, there are still some dentists out here who do those.'

'That's why I'm calling. I need to talk to someone. Maybe the head of their organization.'

'Would you like me to make some calls?'

'What I'd like you to do is find out if by some small miracle their group is on a computer system. It sounds like a small and unusual society. They might be connected through E-mail or a bulletin board. Maybe something like Prodigy. Who knows? But I've got to have a way to get information to them instantly.'

'I'll put several of my staffers on it immediately,' he said.
