A chef was "savagely" murdered when he was caught up in a feud involving his Italian flatmate, the Old Bailey heard.
Donald MacPherson, 60, and Luciano Schiano, 49, were found dead at their flat in Summersell House, west Norwood, in south London, on 20 October 2009.
They suffered multiple stab wounds and were found days after the attack.
Claudio Lamponi, 30, of Norwood, and Massimo Manai, 41, from Sardinia, but of no fixed UK abode, deny the murders.
Mr MacPherson, a chef the Reform Club on Pall Mall, had the "misfortune" of being at home when two men allegedly came round to attack Mr Schiano following a fight over a woman, the court heard.
Mark Heywood QC, prosecuting, said the target of the violence had been Mr Schiano, who the two defendants had each known for years until a recent "falling out".
In August 2009, Mr Schiano had been head butted by Mr Manai after he "unwisely made a pass" at his girlfriend, the Old Bailey heard.
The court heard there had been "no love lost" since that time but neither Mr Lamponi or Mr Manai knew Mr MacPherson.
"His misfortune was simply to be there," said Mark Heywood QC, prosecuting.
The body of the 60-year-old father of four was discovered by police several days after he had failed to turn up at his workplace.
Mr MacPherson, originally from Clydebank, Scotland, suffered 80 injuries and had his face smashed with a clothing iron as he fought back, jurors were told.
Mr Schiano, 49, suffered 26 knife wounds in the "brutal" attack at their shared flat, the court heard.
The court heard that two men had gone to the address "at the dead of night" and had "come there to kill".
The trial continues.
