Many many thanks to Flygon Pirate for giving me all these suggestions. I can't think of a time when this would be set. I'm just using characters. : )

Elizabeth looked out of her cell. She'd been just a tad careless about a month ago, and as a result been caught by the East India Trading Company. The cell she was in looked like it had never been cleaned, and her dress was filthy. Nothing she said could persuade the guard to bring her extra water for washing her clothing, or herself, for that matter. Her usually pale skin was nearly black from lack of washing. Sighing, she stood up and looked out the window again. Nobody was coming. Again. This had been the third time she'd looked out the window, and there was an odd lack of guards. There was a loud commotion in the entrance to the jail. Elizabeth scurried towards the other side of her cell and peered as far as she could towards the entrance. Two guards entered, followed by two more, who were struggling to keep Jack Sparrow in their grasp. Two more guards followed this whole procession. The group walked down to Elizabeth's cell, where the door was opened and Jack was shoved in. The guards quickly ran off, eager to be doing something which neither pirate could determine. They looked at each other, then back at the door. Elizabeth walked over, and pushed it. Much to Jack's surprise, the door swung open. The duo quickly ran out and up the stairs. There still wasn't a guard in sight, and the couple ran off towards the docks. Elizabeth stopped in mid-step.

"C'mon luv, there isn't any time to play games!!" Jack grabbed her arm and tried to drag her along. But the headstrong governor's daughter wasn't about to be persuaded.

"But Beckett has the key. You know, the key to the Chest." That convinced Jack, and Elizabeth ran back towards the office area. She crept along the inside of the hall, and peered into the Lord's office. There, with is back to the door, was Beckett himself. Oddly enough, he was softly singing a song. Elizabeth strained her ears to hear it, and this is what she heard.

"And the keys to the cage, with the devil to pay, we lay to Fiddler's Green!!" Her eyes grew wide, but she didn't let the shock of Lord Beckett singing a pirate song distract her from her mission. She snuck over towards the desk, and silently opened the drawer she'd seen him put the key in. There, on top of everything, was the key. She pulled it out, and slipped it over her head. Using the same precaution, she crept back out of the offices. Then, as fast as she could, Elizabeth ran towards the dock. There was Jack, waiting impatiently.

"What took you so long? We need to move!!" The duo ran towards the Pearl and successfully made their escape.

So maybe it isn't my best. But I like it.
