Roxy Jacenko's book launched as Oliver Curtis' case continues Book launch: Roxy Jacenko. It has been a week investment banker Oliver Curtis and his former best pal John Hartman would undoubtedly rather forget. Mr Curtis stood accused of insider trading, for which he could go to jail, while Mr Hartman was publicly humiliated after turning on his childhood friend. But Mr Curtis' wife, Roxy Jacenko, drew on all her public relations experience to ensure the show went on. Standing trial: Oliver Curtis. On Tuesday, she launched her new book less than an hour after her investment banker husband was committed to stand trial in the Supreme Court for insider trading. The court heard that Mr Hartman and Mr Curtis were just 21 when they allegedly entered into an agreement to illegally profit using Mr Hartman's position as an equities dealer at Orion Asset Management. Under the agreement, Mr Hartman said he would tip off Mr Curtis about trades that would move stock prices, and the two would take advantage. Mr Hartman was subjected to a barrage of accusations about his version of how events played out, as Mr Curtis' lawyers painted him as an unreliable witness who debilitated the Crown case. Notwithstanding the criticisms, magistrate Greg Grogin concluded that "a reasonable jury properly instructed" could convict Mr Curtis of an indictable offence. Mr Hartman spent more than a year behind bars, but meanwhile Mr Curtis popped the question to PR queen Ms Jacenko with an engagement ring said to be worth $200,000, the pair welcomed their first child Pixie-Rose and enjoyed a lavish wedding at Quay Restaurant. A pregnant Ms Jacenko used Otto Ristorante in Woolloomooloo to launch her second book, The Rumour Mill. "It is what it is, and I wasn't going to help being there," she said after the launch. In launching the book, Ms Jacenko thanked her husband and told the intimate gathering he had been her rock during the past few years. Earlier, Mr Curtis' barrister, Murugan Thangaraj, SC, argued that Mr Hartman's evidence was "evasive, untruthful, unreliable and manipulative" and therefore the prosecution could not succeed. He said Mr Hartman could face investigation by the NSW and Victorian police after he was questioned about explosive email exchanges with his brother suggesting race-fixing, as well as the Crime Commission, Australian Federal Police and Tax Office. The prosecution pointed the magistrate towards the paper trail between the two men, which made references, albeit scant, to their trading together, saying that it was significant that Mr Curtis had given no "plausible" explanation for trading data showing positions opened and closed within minutes of Orion's own trading activity. Mr Curtis will be arraigned in the Supreme Court in February.
