Former Queensland Liberal leader Bruce Flegg heard a "bloodcurdling scream" on the night his neighbour Gerard Baden-Clay allegedly murdered his wife, a Brisbane court has been told.

The second day of Baden-Clay's committal hearing is getting underway in Brisbane's Magistrates Court.

The 42-year-old is accused of murder and of interfering with his wife Allison's body, which was found dumped at Kholo Creek at Anstead in Brisbane last April.

Today Dr Flegg said he was sitting in bed on the night of April 19 when he heard a woman scream.

He said it was followed by another scream, identical but softer.

But he said he had no reason to think the two screams were anything to concern the police.

Dr Flegg also told the court Baden-Clay had asked him for a $400,000 loan, an option which Dr Flegg described as "pretty unattractive".

More to come.
