"I understand." He did. Remi was a trouper; she'd never withered before a challenge and had stood side by side with him in mud and snow, under gunfire and pursuit, and she rarely failed to find a bright side. For all that, however, she also loved her comforts. As did he. "Once we get things settled with our mystery bell, we'll head over to Dar es Salaam, get a suite in the Royal, drink gin and tonics on our balcony, and bet on the cricket matches."

Remi's eyes lit up. The Moevenpick Royal Palm was Dar es Salaam's only five-star hotel. She said, "You're singing my song, Sam Fargo."

"But first," he replied, looking at the sun and checking his watch, "we need to get ready for our guests."

WITH THE ARRIVAL of nightfall, the lagoon came alive with the trilling of crickets. In the trees along the shorelines and in the shrubbery atop the floating islands fireflies winked at them. Sam had steered the Andreyale between two of the bigger floating islands and dropped anchor with the bow facing west. The sky was clear, a black backdrop sprinkled with pinpricks of light and a half-moon surrounded by a hazy, prismatic ring.

"Could rain tomorrow," Sam observed.

"Does that wives' tale apply to the Southern Hemisphere?"

"Guess we'll find out."

They sat on the afterdeck sipping coffee in the dark and watching the insect light show. From their position they could see both the mouth of the lagoon and the beach, where they'd erected a makeshift A-frame tent from a canvas tarp they'd found in a storage locker. Behind the canvas came the faint yellow glow of a lantern, and, a few feet outside the tent, was a small bonfire. Sam had enough coconut palm logs to keep embers glowing all night.

Remi yawned. "Long day."

"Go below and get some sleep," Sam said. "I'll take the first watch."

"You're a doll. Wake me in two hours."

A peck on his cheek, and she was gone.

THE FIRST TWO WATCHES were uneventful. Nearing the end of the sixth hour, shortly before three A.M., Sam thought he heard the faint rumble of engines in the distance, but the sound faded. Five minutes later it returned, this time louder and closer. Somewhere to the north. Sam scanned the mouth of the lagoon through binoculars but could see nothing save ripples on the water's surface where the current surged through the inlet. The engines faded again. No, not faded, Sam corrected himself. Died. As if they'd been shut down. He lifted the binoculars to his eyes again.

A minute passed. Two minutes. And then, at the four-minute mark, a shadow appeared in the inlet. Like a bulbous shark's snout, the object seemed to float a few feet above the surface. Moving at less than a walking pace, the Zodiac raft glided noiselessly from the inlet and into the mouth of the lagoon. Thirty seconds later another Zodiac appeared, followed by a third. In single file they drifted for fifty feet before turning in formation to starboard and entering the lagoon proper.
