Animals
A low rumble made Colly's blood freeze. The chug-chug of an engine followed by the clinking of chains started his heart pounding. He peered at where Jaz had disappeared on the barge. "Hurry!" he shouted inside his head. Where was she? Why didn't she get off?
Maybe she was trying.
Maybe she was caught!
He took out his red whistle and gave a short careful toot. No Jaz.
He tooted again, louder and longer this time.
Nothing.
