Henry Seymour, who was hanged for murdering an Oxford woman, went to the gallows protesting his innocence.
In 2015, Memory Lane featured a book written by Oxford-born author Michael Tanner, who suggested a grave miscarriage of justice.
More recently, a court judge has weighed in with his view that there was “reason to doubt that a safe verdict was reached”.
Seymour, a 39-year-old travelling salesman, was convicted of murdering Annie Kempson at her home in St Clement’s in August 1931.

A jury at Oxfordshire Assizes two months later took just 38 minutes to find him guilty of killing the 58-year-old widow.
Mr Justice Swift sentenced him to death and he was later hanged at Oxford Prison after losing his appeal.
Mrs Kempson was found bludgeoned to death in her semi-detached home called The Boundary.
An intruder had hit her on the head, knocking her unconscious, and then plunged a sharp weapon through her throat before escaping with a few pounds.
The murder gripped the nation, with reports appearing in all the national newspapers.
Oxford’s Chief Constable, Charles Fox, called in Scotland Yard to help in the hunt for the killer.

Once detectives heard that Seymour was in the area at the time and his calling card was found in Mrs Kempson’s house, he was arrested. No-one else was considered a suspect.
He appeared before judge and jury in court at County Hall in New Road after being brought through the underground passage from Oxford Prison, where he had been held on remand.
Crowds gathered outside on the opening day of his trial.
Seymour had a long criminal record in Britain and South Africa, including at least one conviction for violence.
But an episode of Murder, Mystery and My Family, shown recently on BBC2, questioned whether the evidence in the murder case stood up.
The murder weapon was never found, the precise time of the murder was never established and no-one could confirm they saw Seymour at the scene.
Numerous defence witnesses said on oath that they had seen Mrs Kempson alive after Seymour had allegedly killed her.

There were also doubts about the testimony of renowned pathologist Sir Bernard Spilsbury.
In the TV programme, one of Seymour’s grandsons questioned whether he was guilty. Barristers Sasha Wass QC, for the prosecution, and Jeremy Dein QC, for the defence, argued the case, and Judge David Radford sided with the defence.
Earlier, in his book, Oxford Murder, author Michael Tanner also questioned the jury’s verdict.
He pointed out that at the initial hearing, Oxford magistrates had taken just “a minute or two” to commit Seymour for trial, despite a plea by his solicitor, Mr R B ‘Bunny’ Cole, that the prosecution had offered only “a chain of circumstantial evidence of the very flimsiest character”.
