Legend has it that a portion of the 'missing millions' plundered by late Philippine dictator Ferdinand Marcos remains in Hong Kong bank accounts to this day.
Hong Kong financial institutions were likewise chosen by Mr Nice author Howard Marks to move large sums of dirty cash around the globe in the 1980s before United States law enforcers cut short a 25-year career in drug smuggling.
Anecdotal and biographical, these accounts of money laundering have tended to fill the gaps in what is an otherwise unspectacular official picture of illicit cash flows in and out of Hong Kong.
Millions of dollars are seized and confiscated annually but the pervading theme since 1989 - when money laundering laws were enacted - is that these funds have largely resulted from drug offences, with 118 convictions for handling dirty cash over the past 15 years suggesting it is not a crime of endemic proportions.
That was until earlier this year, when six people went on trial at the High Court for the largest money-laundering prosecution in Hong Kong, if not globally.
Over a five-year period, a jury heard, couriers strapped notes to their bodies and crossed the mainland border into Hong Kong. They then handed the money over to money-changer Guardecade, which processed the cash through accounts at the Kimberley Road branch of Po Sang Bank, now part of the Bank of China (Hong Kong).
