A little over forty minutes later Africa emerged from the darkness with bluffs of sand shimmering in the moonlight and occasionally the brighter white of waves curling onto the beach. The long peninsula that protected Sandwich Bay was a quarter mile to their south.

“Nice bit of navigating,” Sloane said.

Juan tapped the GPS receiver with a knuckle. “Gladys here gets the credit. GPS has made lazy navigators of us all. I don’t think I could compute my position with a sextant and watch if my life depended on it.”

“Somehow I doubt that.”

Juan backed off the throttle to reduce their wake as they entered the fragile ecosystem. They motored for twenty minutes until reaching the southernmost edge of the bay. Sloane panned the dense wall of reeds with a flashlight as they tracked along the shore looking for the cut in the grass that led to Papa Heinrick’s private little lagoon.

“There,” she said, pointing.

Juan slowed the boat to a crawl and edged its bow into the reeds. He kept a sharp eye on the depth gauge and constantly checked that floating chunks of vegetation didn’t foul the props. The lifeboat cut through the tall grass and the blades made a hissing sound as they scraped the hull and sides of the cabin.

They had covered seventy yards when Juan caught the scent of smoke. He raised his face and sniffed the air like a dog but couldn’t detect it again. Then it came back, stronger, the sooty smell of burning wood. He grabbed Sloane’s wrist so he could cover the lens of her flashlight with his hand.

Ahead he could see the orange glow of a fire, but not the contained fire pit Sloane had described. This was something altogether different.

“Damn.” He gunned the throttles and prayed the water maintained its depth as the boat leapt forward, knocking Sloane into his arms. He steadied her quickly and tried to peer through the curtain of grass that blocked their way.

They suddenly burst into the clearing that surrounded Papa Heinrick’s island. Juan glanced at the depth gauge. There was less than a foot of water under the keel. He jammed the throttles into full reverse, causing a torrent of water to erupt at the stern, and hit the release for the anchor. They hadn’t yet picked up a great deal of speed, so he managed to stop the lifeboat before she grounded.

He idled the engines and only then did he take in the scene around them. The shack perched at the center of the island was a pyre, with flames and embers leaping twenty feet from its thatch and driftwood roof. Papa Heinrick’s overturned fishing boat was also ablaze, but the craft was so waterlogged that the fire hadn’t really caught. Banks of thick white smoke coiled from under the skiff and wafted from the seams of its wooden hull.
