FOUR BOLTS REMOVED BY HAND

Callahan emerged through the smoke with two injured sailors.

“Can you close it?”

Michael seized the manual wheel.

“I can try.”

“If that door doesn’t seal—”

“I know.”

Water climbed over their boots.

Michael threw his weight against the wheel.

It would not move.

“Go!” he shouted.

Callahan grabbed his shoulder.

“We’re not leaving you.”

“If you stay here, nobody leaves!”

Another blast shook the vessel.
