that the dark purple mark on the left side of his face was not his deformity as she had thought, but the livid swelling of a snakebite.
'All right!' Dr. Tarver shouted.
'Swim away!'
Obviously reluctant to give up his leverage, Dr. Tarver released Jamie and swam quickly toward the stern of the boat.
'Jump out!' he shouted.
Still suspicious, Alex pulled off her shoes and stripped off her jeans. Wet jeans could quickly drown you in water like this. She climbed onto the gunwale and dropped into the cold water. As she breaststroked toward Jamie, she sensed movement to her left. Dr. Tarver had not climbed into the boat. He was kicking toward Jamie again. She started to swim freestyle, but Tarver still got there first. As Alex stared in disbelief, he put his big hand on top of Jamie's head and shoved him right through the life ring, deep under the water.
'Save him now,' he snarled.
Alex couldn't see Jamie, but he didn't appear to be struggling. Dr. Tarver held him under as easily as he might an infant. She thought of pulling out the screwdriver, but that was no solution. She'd never overpower Tarver face-to-face.
The answer struck her with the force of revelation. As she dove beneath the waves, her father's voice echoed in her head:
It was an ankle-the smooth ankle of a boy.
Knowing that Tarver was braced for a fight, she expelled all the air from her lungs and jerked the ankle straight down, then swam toward the bottom with all her strength. With a rush of joy, she felt Jamie's body come with her. After a few seconds of kicking, she started trying to tow him laterally, but her oxygen was disappearing fast. She had to surface.
As she kicked upward, she saw a splash above, then a black shape sweeping down toward her, trailing bubbles. Switching Jamie's ankle to her left hand, she drew the screwdriver from her 'bandage' and waited. When the shadow reached for her, she kicked upward and stabbed with savage force.
The tool struck something, but the shadow didn't stop. A powerful hand seized her throat. Alex flung her arm wide and stabbed from the side. An explosion of bubbles enveloped her. Tarver's big body thrashed like a wounded shark's, and then his hand let go. Hope surged through her, urging her to a final blow. She yanked back on the handle of her weapon, but the screwdriver wouldn't pull free.
Terrified that she'd lose Jamie, she released the tool and tried to swim clear, but now her air was truly gone. Lungs burning, she grabbed Jamie beneath both arms and kicked for the gray light above.
She broke through the waves and saw the boat bobbing fifteen meters away. She was shifting Jamie to a lifeguard's carry when Dr. Tarver surfaced directly in front of her. His eyes shone like those of a man in the grip of a religious vision, but something about his mouth was wrong. It sagged the way Grace's had after her stroke. Alex had no idea how to keep hold of Jamie and fight Tarver in the waves, nor had she the strength to do it. But when Tarver's hand rose from the water, it did not reach for her. The hand was open, and it moved to the side of his head, as though searching for a wound. Alex and the doctor understood the horror of his plight at the same moment: the handle of the screwdriver protruded from Tarver's left ear, where the metal shaft had been buried to the hilt.
Tarver's eyes widened as his hand closed around the handle. He seemed about to jerk the screwdriver free, but then some flicker of knowledge overrode his instinct. His hand dropped into the water, and he looked over his shoulder. With a last wild look into Alex's eyes, he turned and began swimming awkwardly toward the boat.
Alex turned in the water and started kicking toward the island. It appeared to be fifty or sixty meters away, not a difficult swim under normal conditions, but now potentially lethal. Her burning lungs and blurred vision told her she'd lost more blood than she knew. Still, she kicked on through the battering waves. Forty meters. Thirty. Her leaden limbs began to sink. Jamie's face was blue, but she could no longer kick. She knew then that they might die within a few meters of the shore.
An image of Grace rose into her mind, and then her father. Then her mother lying unconscious in the hospital.
Her mouth was full of water when she heard a male voice barking orders.
'Can you hear me, Alex?'
She nodded.
'Is there anyone else in the boat?'
She shook her head. 'Jamie,' she gasped. 'Is he alive?'
As if in answer, there was a fit of coughing beside her, then the sound of a boy crying.
'Disable the boat!' shouted Kaiser, getting to his feet. 'Fire at the engine!'
'No,' Alex cried, remembering the disconnected fuel line, which from the roar of the engines, Tarver must have reconnected.
Her cry was drowned by the crack of rifle fire.
She rose onto her elbow and tried to shout. 'Stop…the fuel-'
'What?' called Kaiser, moving back to her.
But the rifle cracked again, and the stern of the fleeing Carrera erupted into flame. A figure leaped onto the starboard gunwale, but before it could jump clear, the speedboat blew apart.
Alex collapsed in the mud, rain falling steadily on her face. She tried to explain about the Pelican cases, but her voice was lost in the squawk of radios, Kaiser's barked orders, and shouts about a man in the water. The pilot of the doctor's helicopter? None of it mattered now. She rolled onto her side and saw Jamie lying beside her, staring at her with wide eyes. But it was Grace looking out through those eyes-and no longer with despair. When Jamie held out a shivering hand, Alex pulled him to her, burying his face in her chest.
She had kept her promise at last.
EPILOGUE
Alex slowed the Corolla and told Jamie to watch for a gravel road on the left. They were driving down a deserted gray road through an endless tunnel of oak trees.
'Are you sure you know where you're going?' asked Jamie.
'I think so. It wasn't that long ago that I was here. I stood with him on that big bridge we just went over.'
Jamie took off his seat belt, got onto his knees on the seat, and propped his elbow on the terra-cotta jar between them.
'Careful,' said Alex.
'Sorry.' Jamie leaned forward and pressed his forehead against the windshield. 'I think I see it. Is that a road?'
'It is. Eagle eyes.'
