In 1896 a double murder of an elderly shopkeeping couple in Petone rocked colonial New Zealand.
They'd been stabbed - and the person who raised the alarm was a man called Stephen Bosher - a market gardener who'd called on them for supplies.
But that wasn't the only name he went by. He was actually a French immigrant called Etienne Jean Brocher who would eventually come to police attention through his colourful past - including jail time for various crimes and being found out as a bigamist.
He was convicted and hanged in 1897 for their murders. But what was the evidence against him?
Was he a victim of colonial prejudices and suspicions of the time? His case has been meticulously researched by Brian Stoddart, an academic and former Vice Chancellor of Melbourne's La Trobe University.
His book is Outcast: The Extraordinary Life and Death of Etienne Jean Brocher.
