Finally the trio reached the mouth of the lagoon and finished their examination of the shoreline, but instead of heading for the inlet they turned again, formed a line abreast, and started checking the floating islands, flashlights scanning each mangrove buttress before moving to the next.“This could be bad,” Sam muttered. “Very bad,” Remi agreed.

The drawn knives had told Sam and Remi everything they needed to know: Whoever these men were, they had no compunction about using violence. Had Sam and Remi been either aboard the Andreyale or in the tent, they would be dead now.“Head back to the Andreyale?” Remi suggested.

“If they decide to board her again, we’ll be trapped.”

“I’m open to suggestions.”

Sam thought for a moment, then said, “How about two birds with one stone?” He explained his plan.

“Risky,” said Remi.

“I’ll make it work.”

“Okay, but only if there’s no other way.”

“Agreed.”

They watched the progress of the Zodiacs. If they continued on their current paths, the one to their right would reach their hiding spot in less than two minutes. The other two were ahead by half a minute. With luck, they’d finish their searches first and turn back toward the mouth.“Cross fingers,” Sam said to Remi.

“Already there,” she replied and kissed him on the cheek. “For a little more luck.”

Sam ducked underwater and pulled himself back through the root system and into open water. Doing his best to keep all three Zodiacs in view, he maneuvered himself around to the back side of the roots. Thirty seconds later, to his left, Hawk Nose and his partner slid into view. Each man scanned his final floating island, then turned and headed back toward the inlet. The last Zodiac was still on course, forty feet away.“?Apurate!”

Hawk Nose called. Hurry up!

Sam’s target raised a hand to acknowledge the order. Thirty feet away . . . twenty feet.

Sam kept moving, pulling himself clockwise around the mangrove roots. He stopped, peeking around the edge. The Zodiac was ten feet away. Sam watched, waited until the nose of the Zodiac disappeared around the opposite side, then glanced back up the lagoon. The other two Zodiacs were a hundred yards away and still moving.

Sam took a deep breath, ducked under with the gaff pole, kicked twice, pulled himself around the roots, and let his eyes pop above the surface. The rear of the Zodiac was five feet away, moving slowly, the driver sitting with one hand on the motor’s throttle as he leaned sideways and scanned the mangrove with his flashlight. Sam did a half kick with his feet and closed to within a foot of the Zodiac. He reached out, gently placed his left hand on the rubber side, then raised the gaff from the water, cocked it back, and flicked it forward as though casting a fishing lure. The gaff’s steel tip caught the man on the side of his head, just above the ear. He let out a gasp, then slumped over the side, his head drooping in the water. Before Sam could make another move, Remi was there, lifting the man’s head and rolling the body back into the Zodiac. Sam looked over his shoulder. Hawk Nose and his partner were two hundred yards away now.“Yaotl!” Hawk Nose’s voice echoed over the water.

“Hurry,” Sam said to Remi, then climbed aboard the Zodiac and took a seat at the motor. “Stay on the port side. I’ll drag you back to the Andreyale.”

Remi swam around and grabbed the oar hook with two fingers. Sam revved the motor, and the Zodiac glided out from behind the mangrove. Sam found the man’s-Yaotl’s-flashlight where it had fallen, picked it up, and aimed it at the other two Zodiacs, which come to a halt. Sam flashed the beam twice and raised a casual hand, praying it would be enough. He held his breath.

Nothing from the Zodiacs. Ten seconds passed. And then the double wink of a flashlight followed by a raised hand. “Yaotl . . . ?Apurate!”

Sam guided the Zodiac to the Andreyale’s stern, using the length of the boat to hide their movements. Remi climbed aboard, and together they rolled Yaotl over the gunwale. He landed with a thump on the afterdeck.“Now what?” Remi asked.

“Tie him up, hands and feet to the cleats, and search him. I’ve got to catch up with my new friends.” Remi opened her mouth to protest, but Sam interrupted: “I need my mask and the binoculars.” She went into the cabin with both items and traded them for Sam’s gaff. “Don’t worry, Remi, I’ll keep my distance.”“And when you can’t any longer?”

“I’ll have a terrible mishap.”

He gave her a wink, revved the engine, and motored away.

HAWK NOSE and the other man had continued on. By the time Sam reached the midpoint of the lagoon, they were turning west into the inlet. Sam mentally recalled the twists and turns of the inlet, did a few quick calculations, and kept going. Fifty feet from the entrance, he slowed to idle and listened. No sound of the other motors. He revved up, kept going, and made the turn. A hundred yards ahead the other two were moving single file through the inlet. Beyond them, about a half mile away, Sam could see the inlet widening into Chumbe Island’s shoals. He lifted the binoculars to his face and scanned the channel. Nothing was moving, and no lights were visible within ten miles-save one. A mile to the southwest, a single white light hovered thirty feet off the water-the international signal for a boat at anchor. The boat itself was bow on, rake stemmed, with a gleaming white superstructure, clearly a luxury yacht. The mother ship, perhaps?

Hawk Nose and his partner veered left and disappeared from view momentarily. Time to prepare for the mishap: Sam throttled down, veered left, and let the Zodiac ground itself on the sand. A quick glance around gave him what he needed: a dagger-shaped rock. He grabbed it, shoved the Zodiac back into the inlet, jumped aboard, and took off again.

So far Sam’s luck was holding. Aside from a few backward glances to make sure “Yaotl” was following, neither Hawk Nose nor his partner slowed to let him catch up. The remainder of the transit took ten minutes, and soon enough Sam could see the other two Zodiacs jostling as they moved into the shoals.“Come on, guys, show me where you’re going,” Sam muttered.

Now clear of the shoals, Hawk Nose and his partner veered left and headed toward the yacht. Two minutes later Sam was himself in the shoals, but he put on a few more degrees left rudder, steering the Zodiac nearly parallel to the bank in which they’d found the bell. Onshore, landmarks began looking familiar. He was within twenty yards of the precipice. It was time.

He grabbed the rock from between his feet, leaned over the side, stabbed the tip into the rubber sidewall, and heaved backward. He repeated the process twice more until he’d created a ragged eight-inch gash. He tossed the rock over the side and checked the progress of the other two Zodiacs: they were a few hundred yards out into the main channel and still heading for the yacht.

It took only twenty seconds for Sam’s sabotage to take effect. The Zodiac began slowing, shuddering and wallowing as water gushed into the sidewall. He gave the throttle one last twist, then let out what he hoped would sound like a panicked scream, then rolled over the side.

He ducked underwater, settled the mask over his face, blew it clear, then clamped the snorkel’s mouthpiece between his teeth. He went still now, floating with just his eyes and the tip of the snorkel above the surface.

His scream had done the trick. Hawk Nose and his partner had reversed course and were heading at top speed toward the rapidly deflating Zodiac, which was now drifting twenty yards to Sam’s left-and directly over the precipice. When the rescuers were fifty yards away, flashlights blinked on and began scanning the surface.“Yaotl!” Hawk Nose called. “Yaotl!” The other man joined in.

Sam had been hyperventilating his lungs for the past minute. Now he took one final deep breath, ducked beneath the surface, and finned toward the bank. He was there in ten kicks. He turned so Hawk Nose and the other were on his right, then begin finning north along the bank, occasionally glancing back to check the location of the flashlight beams. Both Zodiacs had converged on the remains of the third.“Yaotl!” Sam heard through the water. Then again, this time more strident: “Yaotl!”
