He looked at it carefully, finally shaking his head. "We have a cemetery here, but this picture doesn't look like any part of it that I've seen. The house could be any one of a couple of dozen. The tree? Well, it's a rubber tree, so it could be anywhere around here. And then there's the gravestone. It doesn't have a name on it—which probably wouldn't have helped, by the way—just RIP. If I had seen that, I would have noticed it."

I suddenly had an idea. "Suppose the stone had fallen down? After all, I think we can assume that John erected it for the purposes of the painting. Maybe he didn't put it far enough into the ground. Maybe it just fell over."

"Then good luck with that," said Emil. "The yards around most of those houses are completely overgrown. If the tree is still there, it would be fully grown by now. But it might not even be there. A lot of the rubber trees died. Not to sound pessimistic, but if the tree died and the headstone fell over, you've got your work cut out for you."

"We saw some houses, like yours, that have been fixed up. Maybe it was one of those houses," said Sabrina.

"I can ask around, if you like," suggested Emil. "If so, someone would remember it. Where are you staying tonight?" he asked, completely changing gears.

"We had hoped we might be able to solve this in one day," answered Sabrina, "but I think that was a pipe dream. We can stay on the boat."

"Believe it or not, we have a Bed and Breakfast here."

"Here?" I asked.

"We do get tourists . Not a lot, but they usually need a place to stay. I've heard it's not too bad, considering the location, and the food is pretty good. I know three guys checked in yesterday, but they might still have a room available."

We both perked up. "Three guys?" I asked. "Did you see them?"

"No, just heard they were here." Then it dawned on him. "Oh shit. Are they looking for the same thing?"

"It's possible," I said. I turned to Sabrina. "Could be Guidry's men. But if they knew about Fordlandia, why didn't they come earlier?"

"It could also be the Russians. If that's the case, we could be in a lot of trouble. But they never passed us again after we disabled their boat, so it's probably not them." She added, "Whoever it is knows we're here. They probably even know that we're in this house." And like a bad movie, that's when the knock came at the door.

"What do you suggest?" I asked Sabrina. I was suddenly having trouble breathing.

"I guess we answer the door. It's time we confront whoever it is. Maybe we can take them by surprise." As she said it, she pulled out her revolver. "Maybe they won't be expecting this."

"Emil, we're sorry we brought this to your doorstep," I said. "You might want to stay hidden. As I said it, I heard a shotgun being snapped shut. I looked around and saw Emil crouched behind the kitchen counter, with a double-barreled shotgun aimed at the door.
