An inquest into the death of Albertina Choules was opened today by senior coroner Crispin Butler at Beaconsfield Coroners Court.
The 81-year-old's death in Ragmans Lane on Wednesday, July 6, is is the subject of criminal proceedings, with a trial scheduled to take place next year.
Tautvydas Narbutas, 23, of Chiltern Avenue, High Wycombe, is accused of her murder.
At the hearing, a statement was read out by Detective Inspector Andy Shearwood, from the Major Crimes Unit in Taplow.
He said at 6.30am on the day of her death, a phone call was made by Mrs Choules where she made a request for the police.
He said: "A male voice could be heard in the background, after which the telephone line was disconnected."
He said officers arrived at the property to see something on fire, and it soon became clear it was a woman's body.
Emergency services were unable to save the woman, who was later identified as Mrs Choules.
A pathologist gave a report of the cause of death as 'pending' but said it was 'likely to be multiple injuries'.
Mrs Choules was identified with DNA taken from her body, which was compared to that found on a toothbrush at her cottage.
Mr Butler adjourned the hearing until a later date.
The trial is set to begin in Reading Crown Court on Tuesday, January 10.
