They all stood there, staring, shading their eyes against the sunlight. It was a beautiful sight: a hill shaped like a giant breast, covered in red flowers. Amy took out her camera, started snapping pictures.

The cleared ground was a different color than the fields they'd crossed earlier. The fields had been a reddish brown, almost orange in spots, while this was a deep black, flecked with white, like frost rime. Beyond it, the path resumed, winding its way up the hillside. It had grown strangely quiet, Stacy suddenly realized; the birds had fallen silent. Even the locusts had stopped their steady thrumming. A peaceful spot. She took a deep breath, feeling sleepy, and sat down. Eric did, too, then Pablo, the three of them in a row. Mathias was passing his water bottle around again. Amy kept taking pictures-of the hill, the pretty flowers, then of each of them, one after another. She told Mathias to smile, but he was peering up the hillside.

"Is that a tent?" he asked.

They turned to look. There was an orange square of fabric just visible, at the very top of the hill. It was billowing, sail-like, in the breeze. From this distance, with the rise of the hill partly blocking their view, it was hard to tell what it was. Stacy thought it looked like a kite, trapped in the flowering vines, but of course a tent made more sense. Before anyone could speak, while they were still peering up the hill, squinting against the sun, there came an odd noise from the jungle. They all heard it at the same time, while it was still relatively faint, and they turned, almost in unison, heads cocked, listening. It was a familiar sound, but for a few seconds none of them could identify it.

Jeff was the one who finally put a name to it. "A horse," he said.

And then Stacy could hear it, too: hoofbeats, approaching at a gallop down the narrow trail at their back.

Amy still had her camera out. Through her viewfinder, she watched the horse arrive; she took its picture as it burst into the clearing: a big brown horse, rearing to a stop before them. On its back was the Mayan man who'd approached them beside the well in the little village. It was the same man, but he seemed different now. In the village, he'd been calm and distant, even aloof, with something that felt almost condescending in his approach to them, a weary parent dealing with un-mannered children. Now all this had vanished, replaced by an air of urgency, even panic. His white shirt and pants were splashed with green stains from riding so rapidly through the trees. He'd lost his hat, and sweat was shining on his bald head.

The horse, too, was agitated: lathered, snorting, rolling its eyes. It reared twice, frightening them, and they backed away, retreating farther into the clearing. The man began to shout, waving his arm. The horse had reins but no saddle; the man was riding bareback, his legs clinging to the big animal's flanks like a pair of pincers. The horse reared once more, and this time the man half-fell, half-jumped to the ground. He was still holding the reins, but the horse was backing away from him, jerking its head, trying to break free.

Amy took a picture of the ensuing tug-of-war, the man struggling to calm the horse as the animal pulled him, step by step, back toward the trail. It was only when she stopped peering through the viewfinder that she noticed the gun on the man's belt: a black pistol in a brown holster. He hadn't been wearing it in the village; she was certain of this. He'd put it on to come chase them. The horse was too frantic; the man couldn't calm it, and finally he just relinquished the reins. Instantly, the animal turned, galloped off into the jungle. They listened to it crashing through the trees, the sound of its hoofbeats gradually diminishing. Then the man was shouting at them again, waving his arms over his head, pointing back down the trail. It was hard to tell what he was trying to say. Amy wondered if it had something to do with the horse, if he somehow blamed them for the animal's frenzy.

"What does he want?" Stacy asked. Her voice sounded frightened-like a little girl's-and Amy turned to look at her. Stacy was holding Eric's arm, standing a little behind him. Eric was smiling at the Mayan, as if he thought the whole encounter must be some sort of joke and was waiting for the man to confess to this.

"He wants us to go back," Jeff said.

"Why?" Stacy asked.

"Maybe he wants money. Like a toll or something. Or for us to hire him as a guide." Jeff reached into his pants pocket, pulled out his wallet.

The man kept shouting, pointing vehemently back down the path.

Jeff removed a ten-dollar bill, held it out to him. "¿Dinero?" he said.

The man ignored this. He made a shooing motion with his hand, waving them out of the clearing. They all stood there, uncertain, no one moving. Jeff carefully folded the bill back into his wallet, returned the wallet to his pocket. After a few more seconds, the man stopped shouting; he was out of breath.

Mathias turned toward the flower-covered hill, cupped his hands around his mouth. "Henrich!" he yelled.

There was no answer, no movement on the hillside except the gentle billowing of that orange fabric. In the distance, there was the sound of hoofbeats again, coming closer. Either the man's horse was returning or another villager was about to join them.

"Why don't you hike up the hill, see if you can find him?" Jeff said to Mathias. "We'll wait here, try to sort this out."

Mathias nodded. He turned, started across the clearing. The Mayan began to shout again, and then, when Mathias didn't stop, the man pulled his pistol from its holster, raised the gun over his head, fired into the sky.

Stacy screamed, covering her mouth, backing away. Everyone else flinched, instinctively, half-ducking. Mathias turned to look, saw the man aiming the pistol at his chest now, and went perfectly still. The man waved at him, yelling something, and Mathias came back, his hands in the air, to join the others. Pablo, too, raised his hands, but then, when nobody else did, he slowly lowered them again.

The hoofbeats came closer and closer, and suddenly two more horsemen burst into the clearing. Their mounts were just as agitated as the first man's had been: white-eyed and snorting, sweat shining on their flanks. One of the horses was pale gray, the other black. Their riders dropped to the ground, neither of them making any attempt to hold on to their reins, and the horses immediately turned to gallop back into the jungle. These new arrivals were much younger than the bald man; they were dark-haired, leanly muscular. They had bows slung across their chests, and quivers of thin, fragile-looking arrows. One of them had a mustache. They began speaking with the first man, very rapidly, asking him questions. He still had his pistol pointed in Mathias's general direction, and as they talked, the other two men unslung their bows, each of them nocking an arrow.

"What the fuck?" Eric said. He sounded outraged.

"Quiet," Jeff ordered.

"They're-"

"Wait," Jeff said. "Wait and see."

Amy pointed her camera at the men, took another picture. She could tell it wasn't capturing the drama of the moment, that she'd have to back up to do this, so she could get not only the Mayan men with their weapons but also Jeff and the others, standing there, facing them, everyone looking so frightened now. She retreated a handful of steps, peering through her viewfinder. It felt safer like this, more distant, as if she were no longer part of this strange situation. Four more steps, and Jeff was in the frame, and Pablo, and Mathias, too, with his hands still raised. All she had to do was go a little farther and Stacy and Eric would appear; then she could take the picture and it would be exactly what she wanted. She took another step backward, then another, and suddenly the Mayans were shouting again, all three of them, at her now, the first man pointing his pistol, the other two drawing their bows. Jeff and the others were turning to stare at her in surprise-yes, there was Stacy now, on the right-hand side of the frame-and Amy took another step.
