My God, those dark-brown bumps scattered every­where . . . they're the eyes and snouts of . . . yes, crocodiles, lurking there in wait, hoping I'm dumb enough to wade in. Forget what Alan Dupre said. This is definitely not "Dis­neyland."

Then I glanced upstream and caught sight of a string of mahogany dugout canoes tied along the shore. They were huge, about fifteen feet long and three feet wide, and clearly designed to be crocodile-resistant. They . . .

Wait a minute. Lou said Sarah was found in a dugout canoe that had drifted all the way down the Rio Tigre to where it joins the Usumacinta. One more clue she might have been here. Maybe I was closing in. Yes!

I glared back at the crocodiles' unblinking reptile eyes and tried to get my mind around the fact Sarah could have stood right where I was standing, or been set adrift from here in a coma, to float downstream. Seeing that vision, I felt un­bidden tears trailing down my cheeks. And the questions I had kept piling up. Was this the location of Alex Goddard's "miracle" clinic? Why was Baalum such a high-security se­cret? What was the connection between this place and Sarah's ravaged mind and body? I wanted to know all of it, and by God I would.

This was the farthest I'd ever been from "civilization," though I was trying not to let that fact sink in too deeply. The water was green and full of small aquatic creations, but I managed to find a reasonably un-mossy spot and—still keeping an eye on the leering crocodiles—splashed my face. It felt good, even if it was filthy. . . .

Okay, I'd seen enough of the river. I raised up and stretched. Time to go.

My hopes at war with my nerves, I turned my back on the scummy, fetid Rio Tigre and headed back up the jungle trail toward the plaza.

When I got there, I was struck all over again by the vision of the pyramid. Something like it might have been here origi­nally, but in any case it had been completely redone, with newly cut yellowish stones and white lime plaster, an exotic castle nestled in the green lap of the rain forest, rising above the square like a haunting presence. It must have been well over a hundred feet high, a stone wedding cake with a dozen steep tiers between the ground and the platform at the top, which also was square and roughly fifteen feet on the side.

Standing there gazing at it, I think I'd never felt more disoriented. Sarah, Sarah, how could we both end up here, at the last outpost of the known world? But seeing is believ­ing. I took a deep breath, then turned down the pathway toward the thatch-roofed huts.

Through the mist it was gradually becoming clear that Baalum actually was a village, and a sizable one. The walk­way led past a string of clearings, each with clusters of one-room huts built in the ancient, classical style, with walls of mud over rows of vertical saplings, their roofs and porches peaked with yellow-green thatch weathering to browns and grays. The structures, outlined starkly against the towering green arbor of the forest above, were grouped around paved patios. It all was neat and meticulous, like a jungle Brigadoon. Although the effects of the storm were every­where—blown thatch and bamboo—I still felt as if I'd fallen into a time warp where clocks had gone backward. What . . . ?
