Fiona screamed. She was staring over John's shoulder at the Nipponese 
youths. John turned around to see that there were only two of them now; the 
sick one was gone, and the other two had flung their bellies across the 
gunwale and stretched out their arms, fingers like white rays shining into the 
black water. John felt Fiona's arm pull free from his grasp, and as he turned 
toward her, he just saw her vaulting over the rail.
