Whilst Macky and the girls are minding Samuel’s shop, a petty thief steals a piece of jewellery. The silver fish has information vital to the rebel movement engraved on it and if it falls into Roman hands, there will be serious consequences. Macky can’t figure out how to get the fish back, but after telling Leah the story of a resilient John being beaten by the authorities for the crime of healing people, all becomes clear. Moments after getting the fish back, the bars of the harbour prison slam shut on the kids. Just as things are looking desperate, and it seems the gang are to be sent to the salt mines as slaves, Macky remembers the story of Shadrach and the Furnace. Samuel intervenes and creates an elaborate ruse that sets everything right.
