Until now.

1935: Meet Lottie Lyons, ten-year-old trickster, thief, and girl about the streets. Living a double life, she treads a balancing act between dutiful Catholic daughter and making a quick quid in Surry Hills. Life is bursting with excitement and vibrancy, and Lottie doesn't want to miss one minute of it. This is her story, of a time when the crims were bad, the cops were corrupt, and it didn't pay to squeal.

Eighty years later, Lottie is prepared to talk. Many had died with the secret intact, but is Lottie at last about to lift the lid and make the Shark Arm Unhooked?
