Outside Parker could see the green water rising around the cabin.

He backed away, ducked his head, threw himself with all his strength against the door.

Under the driving impact of his body, the door was knocked open. The mass of synthetic fabric in his arms, Parker catapulted through the opening and into the sea. He hit with a terrific splash. Mercedes followed him. Parker, treading water and working with the valve that would release the gas and inflate the raft, saw that Retch was still standing in the door of the 'copter.

"What am I going to do?" Retch screamed.

"Jump."

"But I can't swim."

"Then wait until I get this goddamned raft inflated. Ugh!" Parker's voice went into silence as arms came up out of the water and closed around his neck with a grip of death.

Mercedes, in a panic that often comes to people catapulted suddenly and unexpectedly into the water, was grabbing the nearest source of potential safety.

"Let go!" Even as he spoke, Parker felt her arms close even tighter around his neck. He knew then that she was not going to let go. She was pulling him under with her.

Giving one final jerk at the valve of the gas container, Parker found himself pulled under water.
