Flash Jim: The astonishing story of the convict fraudster who wrote Australia's first dictionary

The astonishing story of James Hardy Vaux, writer of Australia's first dictionary and first true-crime memoir

If you wear 'togs', tell a 'yarn', call someone 'sly', or refuse to 'snitch' on a friend then you are talking like a convict.

These words, and hundreds of others, once left colonial magistrates baffled and police confused. So comprehensible to us today, the flash language of criminals and convicts had marine officer Watkin Tench complaining about the need for an interpreter in the colonial court.

Luckily, by 1811, that man was at hand. James Hardy Vaux - conman, pickpocket, absconder and thief, born into comfortable circumstances in England - was so drawn to a life of crime he was transported to Australia … not once, but three times!

Vaux's talents, glibness and audacity were extraordinary, and perceiving an opportunity to ingratiate himself with authorities during his second sentence, he set about writing a dictionary of the criminal slang of the colony, which was recognised for its uniqueness and taken back to England to be published.

Kel Richards tells Vaux's story brilliantly, with the help of Vaux's own extraordinarily candid memoir of misdeeds - one of the first true-crime memoirs ever published. Kel's book combines two of his favourite subjects: the inventiveness, humour and origins of Australian English, and our history of fabulous, disreputable characters.

With echoes of The Surgeon of Crowthorne as well as Oliver Twist, Flash Jim is a ripping read - especially for those who appreciate the power of words and the convict contribution to our idiom.
