Cargo Breach

You wake suddenly. When you look out the porthole, you see that it's dark outside. It should be light. You must have overslept. Why didn't anyone wake you? Maybe they felt sorry for you after you got seasick during yesterday's storm.

You jump out of your bunk and quickly get dressed. You then realize that everything is quiet. Too quiet. There's not even the familiar rumble of the ship's steam engine, only the rhythmic beat of the ocean waves against the hull.

Something is wrong. But what?
