Pirates of the Caribbean: The Price of Freedom

when suddenly he’d had to switch to plain water, was the inability to
sleep. He had managed to go nearly a week in the Sentinel’s brig,
unable to sleep more than a few minutes at a time. That was one of the
main reasons he’d begun exercising.
After counting off the paces around the perimeter of his new cell,
Jack made himself walk five miles every day. He figured out a way to
chin himself on the top of the cell door. It became a challenge to figure
out how to stay as fit as possible in the little cell. If his moment ever
came—and surely, at some point, Joe the Jailer would grow careless,
or someone would come to take him out of there for some reason—
Jack wanted to be ready to run.
In time-honored prisoner tradition, he found a small shard of stone
on the floor of his cell, and used it to mark off the days as they passed.
He’d done the same thing while in the brig, so Jack kept a running tally.
It had been thirty-five days since his capture when they brought
Robby Greene into the jail, and locked him up in the cell next to Jack’s.
Jack and Robby gripped hands through their common bars, then
stood there grinning at each other. “I’m glad to see you, mate,” Jack
confessed, “though it’s a terrible thing to admit. I’d hoped they let you
go.”
“No such luck,” Robby said. “They just locked me in the brig on a
different ship, and I got to go with the Larkspur when they went
searching for Kerma. Of course I couldn’t see much, from the brig, but I
saw enough to be sure they’ve changed the illusion, Jack.”
“I told Amenirdis to,” Jack said. “Did you feel anything?”
“No. All I could find out from the cabin boy, who had the
responsibility of looking after me, was that they tried for five days to
sail east from your bearings, and they never saw a thing. They came
back to the basic bearings several times, then headed out again in
overlapping directions, but found nothing. There were three ships, all
crossing and recrossing each other’s wakes, sailing in circles.”
“A hopeful sign, then,” Jack said. “Maybe nobody will ever find
Kerma. Do you know what happened to the Wench?”
“They put one of the mates from another ship aboard her and
sailed her back to Calabar, Jack,” Robby said. “She’s tied up at the
dock. I saw her when they brought me off the Larkspur.”
