The inquest into the death of Peaches Geldof will start on Wednesday (July 23), at Gravesend Old Town Hall in Kent.
The mum-of-two was found dead at her home in Wrotham, Kent, on April 7, after a suspected heroin overdose.
A post-mortem examination carried out at Darent Valley Hospital in Dartford proved inconclusive, prompting further tests to be conducted.
A preliminary inquest in May, which lasted just 10 minutes, revealed the 25-year-old was found face down on a bed by her husband, Thomas Cohen.
Their youngest son, Phaedra, was in another room in the house. Police said at the time that 'recent levels of heroin could have played a role'.
However a cause of death has not yet been established.
Wednesday's inquest could establish whether Peaches took her own life.
Amongst the unanswered questions the inquest is expected to explore are:
• Peaches spoke to a friend the night before she was found. Who was that friend, and what was said in that conversation? This is particularly pertinent as, according to DCI Paul Fotheringham, from Kent Police: "To all her friends and family... there was no cause for concern."
• How recently had Peaches taken heroin? DCI Fotheringham told the inquest: "Forensic samples were obtained and the results concluded the recent use of heroin and that the levels identified were likely to have played a role in her death."
• Why was there no evidence of drugs paraphernalia in the house?
• Where had she got the drugs from? If heroin did play a part in her death, the source of the Class A substance will need answering.
• What other factors could have been involved? Just because heroin was 'likely' to have played a role in Peaches' death, it wasn't conclusive, which could mean there were other causes.
