'Maybe we'll be lucky this time,' I said to Wesley as Marino headed our way.

'We're going to need all the luck we can get,' he said, staring off into dark woods.

East of us was the outer limits of the thirty-seven acres known as the Ramble, the isolated area of Central Park famous for bird-watching and winding footpaths through dense, rocky terrain. Every guidebook I had ever seen warned tourists that the Ramble was not recommended for lone hikers at any season or time of day. I wondered how Gault had enticed his victim into the park. I wondered where he had met her and what it was that had set him into motion. Perhaps it was simply that she had been an opportunity and he had been in the mood.

'How does one get from the Ramble to here?' I asked anybody who would listen.

The officer stirring dental stone met my eyes. He was about Marino's age, cheeks fleshy and red from the cold.

'There's a path along the lake,' he said, breath smoking.

'What lake?'

'You can't see it real well. It's frozen and covered with snow.'

'Do you know if this path is the one they took?'

'This is a big park, ma'am. The snow's real messed up in most other places, like the Ramble, for example. Over there, nothing - not ten feet of snow - is going to keep away people after drugs or an encounter. Now here in Cherry Hill, you got another story. You got no cars allowed and for sure the horses aren't coming up here in weather like this. So we're lucky. We got a crime scene left.'

'Why are you thinking the perpetrator and the victim started in the Ramble?' asked Wesley, who was always direct and often terse when his profiler's mind was going through its convoluted subroutines and searching its scary database.

'One of the guys thinks he may have spotted her shoe prints over there,' said the officer, who liked to talk. 'Problem is, as you can see, hers aren't very distinctive.'

We looked around snow that was getting increasingly marred by law enforcement feet. The victim's footwear had no tread.

'Plus,' he went on, 'since there may be a homosexual component, we're considering the Ramble might have been a primary destination.'

'What homosexual component?' Wesley blandly asked.

'Based on earlier descriptions of both of them, they appeared to be a homosexual couple.'

'We're not talking about two men,' Wesley stated.

'At a glance, the victim did not look like a female.'

'At whose glance?'

'The Transit Police. You really need to talk to them.'

'Hey, Mossberg, you ready with the dental stone?'

'I'd do another layer.'

'We've done four. We got a really good shell, I mean, if your stuff is cool enough.'

The officer whose surname was Mossberg squatted and began to carefully pour viscous dental stone into a red wax-coated impression. The victim's footprints were near the ones we wanted to save, her foot about the same size as Gault's. I wondered if we would ever find her boots as my eyes followed the trail to an area some fifteen feet from the fountain, where impressions became those of bare feet. In fifteen steps, her bare footprints went straight to the fountain where Gault had shot her in the head.

As I looked around at shadows pushed back from the lighted plaza, as I felt the bite of intense cold, I could not understand this woman's mind-set.
