A City worker accused of stealing millions was well liked by her boss who lent her thousands, a court heard.
Joyti De-Laurey denies the charges against her
Jennifer Moses lent Joyti De-Laurey £40,000 to buy a new home, Southwark Crown Court was told.
Ms Moses, then a managing director at investment bank Goldman Sachs, also arranged for private medical care for her personal assistant, the jury heard.
Ms De-Laurey, 34, from North Cheam, Surrey, denies stealing nearly £4.5m from several bankers over two years.
Her husband Anthony, 50, and her mother, Dr Devi Schahhou, 55, deny money laundering.
Ms Moses was the first witness called in the trial, which is expected to last two months.
She said Ms De-Laurey had started working for her in 1998 as a temporary PA.
But Ms Moses found her to be "better than most" PAs she had worked with and supported her application to become a full-time member of staff.
She also successfully lobbied for Ms De-Laurey's annual bonus to be increased and said she had "great respect for her as a professional".
Ms Moses also offered to pay for her secretary to go to New York for private medical treatment when Mrs De-Laurey told her "that her cancer had recurred", the trial heard.
The Crown claims Mrs De-Laurey stole more than £1m from investment accounts belonging to Ms Moses and her husband Ron Beller.
Signature repeatedly forged
Ms Moses denied authorising a string of cheques and other transfers, worth up to £220,000 a time, to individual firms and the Bank of Cyprus.
Her husband's signature had been repeatedly forged, the court was told.
"She was a thief," said Ms Moses.
Jeremy Dean QC, defending, said Ms Moses had been left "extremely angry" when her PA refused to leave Goldman Sachs and work for her when she left the bank.
He also suggested Mrs De-Laurey had been given responsibility to ensure Ms Moses's accounts were "topped up" with money from investment accounts to ensure bills were paid - something denied by Ms Moses.
Mrs De-Laurey denies obtaining money transfers by deception and using false cheques between 27 June 2000 and 26 April 2002.
The case continues.
