“I’m not sure. The first time it passed over it was moving fast, but it swung around almost immediately, then made two more passes. They’re either curious about this spot, or they know we’re here.”
“Where’s the dinghy?”
Remi pointed off to the left and Sam could see a few inches of gray rubber jutting from the foliage. “I got it under cover as quickly as I could.”
“Good.” Sam thought for a moment. “Let’s get into the cave. If they decide to land and look around, that’s our best hiding spot.” Ears tuned for any sign of the Bell’s return, Sam shed his gear and handed it over to Remi, who started putting it on.
“What’re you going to do?” she asked.
“You cross the lagoon and slip into the cave and wait for me. There’s a clockwise current in there, so watch yourself. Take up the slack on the rope and stay close to the entrance.”
“Three tugs from my end is emergency; two for all okay, stay put.”
“Got it.”
“I’ll bring the dinghy over and try to get it inside. We’ll wait until it’s dark, then see what we can see.”
Remi nodded, finished donning the dive gear, took one last look around, then crawled into the water and slipped beneath the surface. Sam watched her bubble trail cross the lagoon, then slip out of sight into the cave. Next he crawled through the underbrush to where Remi had hidden the dinghy. He went still and closed his eyes, listening, but heard nothing.
After stuffing all their loose gear into their two SealLine dry bags and securing them to the cleats, he tied the dinghy’s eight-foot painter line around his belt, slipped into the water, and started breast-stroking across the lagoon. He was halfway across when suddenly from the direction of the beach he heard the pounding of rotors. Even as he looked over his shoulder, the Bell appeared over the tops of the palms and stopped in a hover above him. The door was open, and a figure in dark coveralls was leaning out and looking down at him. It wasn’t Frobisher’s kidnapper, Arkhipov, Sam realized immediately, but the other one, whose photo Rube had e-mailed to him—Kholkov. Nor was there any mistaking the stubby cylindrical object in Kholkov’s hands: compact submachine gun.
He took a quick gulp of air, flipped over, and dove, his head disappearing beneath the surface just as the dinghy’s side tube exploded with a whoosh. The water rippled above him and in the corners of his eyes he saw bullets arcing through the water leaving trails of froth in their wake. The dinghy trembled with each bullet impact, popping and hissing, then collapsed in on itself and slipped beneath the surface, the trolling motor dragging it down stern first.
Sam kicked his legs hard, arms spread wide as he pushed and pulled himself toward the cave entrance. The firing stopped for two seconds—Sam thought, reloading—then resumed, peppering the surface like hail, the bullets penetrating four feet before their thrust fell off and they fell harmlessly to the bottom. Everything went dark as he slipped beneath the rock arch. The pop-pop-pop of gunfire and the thumping of rotors became muffled.
He rolled over and kicked upward, hand groping for the ceiling. Rope . . . rope . . . come on. . . . He felt something brush his feet: the dinghy. Sinking toward the bottom, it had been caught by the cave’s inflow. He felt a tug on his belt as the painter line went taut, felt himself being dragged along. He was distantly aware of muffled gunfire continuing outside. His fingers touched the rope; he drew his dive knife from its calf sheath and sawed through it. Then he was moving, being sucked inside.
Lungs aching, head pounding from oxygen deprivation, Sam fumbled, trying to knot the rope around the knife’s haft. The knife slipped from his fingers, bumped off his chest. He caught it, tried again, managed to work a square knot, then kicked for the surface and broke into air. To the right, in the corner of his eye, he saw Remi clinging to the rock wall. He felt the vortex seize him, start pulling him along.
“Sam, what—”
“Gimme all the slack you got!”
Sam tossed the knife in a high arc that took it up and over the catwalk. As it plunged into the water he was already kicking that way, hand reaching for the rope. Suddenly he was jerked away from it, toward the wall, as the dinghy was pulled deeper into the circular current.
“Remi, the rope, throw it!”
“Coming!”
He heard splashing, saw her stroking behind him. The dinghy was full deadweight now. He was jerked beneath the surface; water gushed into his mouth and nose.
“Grab it!” Remi called. “Right in front of you!”
Sam felt something brush his cheek and he slapped at it. His fingers touched the rope and he closed his fist around it. He jerked to a stop.
He caught his breath, waiting for the sparkling behind his eyes to subside, then looked over his shoulder.
Remi was hanging half out of the water from the other end of the rope. The dive light dangled from her belt loop, casting dancing shadows over the walls.
“Nice toss,” Sam said.
“Thanks. Are you okay?”
“Yeah, you?
“Just barely.”
They hung still for a few moments, getting their bearings, then Sam said, “I’m going to hoist you up to the catwalk. Tie off the rope and then I’ll join you.”
