Tory kept calm. She told herself that there were four other ways out of the superstructure and that she could always smash the glass in the bridge if the wing doors were also sealed. She first examined the other doors on the main deck before climbing another set of steps to the bridge. She knew she would get out of this, but as she approached the door leading to the command deck, a deep dread welled up. Although they’d killed the entire crew, the pirates had taken the time to seal the ship like a coffin. They wouldn’t have left such an obvious means of escape. Her long fingers trembled when she touched the knob. It turned.

Tory pushed against the solid steel door, but it wouldn’t open. It didn’t even creak. There were no large windows she could crawl through, no porthole big enough for her to wiggle out. She was trapped, and that realization destroyed any composure she’d been able to maintain. She threw her body at the door, slamming her shoulder into it again and again until her arm was bruised down to her elbow. She screamed until her throat was raw, then fell back against the door and allowed herself to slide to the deck. She sobbed into her hands, her dark hair falling around her face.

The Avalon shifted suddenly, and the lights flickered. The water pouring into her lower compartments had found someplace new to flood. The shudder sent a jolt through Tory. She wasn’t dead yet, and if she could stop the ship from sinking, she’d have the time to figure a way out. She’d seen a cutting torch in one of the workshops. If she could find it she would burn her way out.

Now as energized as she was in those first desperate seconds when she heard the scream — she was certain now it had been Dr. Halverson, a genteel oceanographer nearing seventy — Tory launched herself from the floor and ran back the way she’d come. She passed through the crew’s accommodation block and reached a set of stairs that descended into the engineering spaces. She felt the first cold rush of air as she reached the bottom landing. The sound of flooding was like the roar of a waterfall.

She stood in a small antechamber with a single watertight door leading into the engine room. She put her hand to the metal. It was still warm from the big diesels. But when she placed her hand low down, next to the bottom jamb, the steel was icy to the touch. She’d never been to the engine room and didn’t know its layout. Still, she had to try.

“Here we go.” Her voice quavered as she undogged the hatch.
