A girl saw part of an attack during which her father was stabbed to death after robbers forced their way into the family home, a court has heard.
John Monckton and his wife Homeyra were attacked at home
Banker John Monckton, 49, was stabbed in the chest at the house in Chelsea, west London last November, an Old Bailey jury was told on Monday.
His wife Homeyra, 46, was stabbed twice in the back, but survived.
Damien Hanson and Elliot White, both 24, deny the murder of Mr Monckton and the attempted murder of Mrs Monkton.
Mr Hanson, of no fixed address and Mr White, from Shepherds Bush, west London, also both deny wounding with intent.
Mr Hanson denies robbery, but the court was told that Mr White had pleaded guilty to robbery.
The court was told Mr Monckton opened the door after seeing Mr White in a postman's uniform, holding a package.
Richard Horwell, prosecuting, said: "Every householder's nightmare became a reality for the Monckton family. What followed was an appalling episode of violence."
As the banker released the door chain, the two men pushed the door open, said Mr Horwell.
Mrs Monckton had joining her husband in trying to keep the door shut.
'I am bleeding'
The men took a pair of costume jewellery earrings, two rings, a watch and a purse from Mrs Monckton, Mr Horwell said.
She was attacked and robbed by the stairs leading to the first floor where the couple's nine-year-old daughter, Isobel, was sleeping, the court heard.
"In the course of the attack she shouted out to her husband `I am bleeding'," said Mr Horwell.
Mr Monckton was fighting with Mr White by the front door, the court heard.
Mr Horwell said Isobel had seen part of the attack.
"When the robbers left she came downstairs," Mr Horwell said.
"The sight which confronted that girl is almost impossible to imagine but she is a very brave girl and at her mother's request she rang 999 and closed the front door and put on the chain."
Richard Horwell said traces of Mr White's blood were found at the banker's home.
Mr Hanson left behind no scientific evidence, but Mr Horwell said: "That he was present we suggest is beyond doubt."
The trial continues.
