A Queensland man accused of murdering his wife told police who were investigating her disappearance she dressed like a "hooker".
It was just one of the disparaging comments John William Chardon, 71, told police in the weeks after Novy Chardon vanished in February 2013, amid a bitter divorce dispute.
Chardon says his wife was selfish, acted strangely and that he had to be careful what he told her because she "goes off", in a police interview played to a jury in his Supreme Court murder trial on Tuesday.
In the interview recorded more than two weeks after the 34-year-old went missing, he told the officers he didn't know what had happened to his wife.
"I don't know a bloody thing... All I know is I didn't do anything to her," Chardon said.
He said he remembered Ms Chardon saying words to the effect that she was going, or had to go, away before her disappearance.
He told the officers she wore tight shorts "like a hooker" before she went missing.
Chardon also spoke of the divorce dispute during the long interview during which even his own lawyer reminded him to keep on track.
The millionaire lubricant businessman can be heard telling the officers he gave her a $1200 weekly "allowance", she had $60,000 worth of handbags and she was selfish.
"I mean she's selfish like you wouldn't believe," Chardon said
Under questioning from police he said he had been "shocked" to receive a letter from Ms Chardon's divorce lawyer at 3pm on the day she later disappeared - February 6, 2013.
He said he asked her about the letter later that night but she "totally ignored" him.
Chardon said he took a sleeping pill that night.
When he woke the next day, Chardon said his wife was missing along with her car, laptop and other belonging.
Chardon pleaded not guilty to murdering his wife when the trial began two weeks ago.
The jury has heard the couple met in 2000 and were wed about a month later.
Their marriage began to fall apart around 2009, when Ms Chardon told a friend her husband was having an affair.
They separated in 2012, but continued to live together while both were having affairs.
Ms Chardon's body has never been found but she hasn't left the country, seen a doctor or used her bank accounts since she disappeared.
The trial continues on Wednesday.
