A group of Convicts stole the Cyprus, a supply vessel carrying a group of Convicts to Macquarie Harbour. They dumped the officers and crew on shore and sailed off to Japan where they pretended to be shipwrecked British mariners. They were sent back to Britain as shipwrecked sailors. Unfortunately one of them was strolling through London town when he met an ex-police constable from Hobart town who recognised his tattoos.
