For the first time we've heard detailed allegations and confessions which shed light on the circumstances leading up to the murder, here in China, 18 months ago, of Neil Heywood - a British business consultant.
Mr Heywood was involved with the family of a corrupt Chinese communist party leader Bo Xilai. It's claimed he helped with the running of a property company and was given shares in the firm.
Bo is now on trial accused of bribery and abuse of power. Today his wife gave video evidence claiming that Neil Heywood had threatened their son and demanded £1.4 million when a property deal went sour.
