"little doubt" Druitt's own family believed him to have been the murderer. Macnaghten's memo was eventually discovered in his personal papers by his daughter, Lady Aberconway, who showed them to British broadcaster Dan Farson. A slightly different abridged copy of the memo found in the Metropolitan Police archive was released to the public in 1966. Farson first revealed Druitt's initials "MJD" in a television programme in November 1959. In 1961, Farson investigated a claim by an Australian that Montague's cousin, Lionel Druitt, had published a pamphlet in Australia entitled "The East End Murderer – I knew him", but the claim has never been substantiated. Journalist Tom Cullen revealed Druitt's full name in his 1965 book Autumn of Terror, which was followed by Farson's 1972 book Jack the Ripper. Before the discovery of Macnaghten's memo, books on the Ripper case, such as those written by Leonard Matters and Donald McCormick, poured scorn on stories that the Ripper had drowned in the Thames because they could not find a suicide that matched the description of the culprit. Cullen and Farson, however, supposed that Druitt was the Ripper on the basis of the Macnaghten memorandum, the near coincidence between Druitt's death and the end of the murders, the closeness of Whitechapel to Druitt's rooms in the Inner Temple, the insanity that was acknowledged by the inquest verdict of "unsound mind", and the possibility that Druitt had absorbed the rudimentary anatomical skill supposedly shown by the Ripper through observing his father at work. Since the publication of Cullen's and Farson's books, other Ripper authors have argued that their theories are based solely on flawed circumstantial evidence, and have attempted to provide Druitt with alibis for the times of the murders. On 1 September, the day after the murder of Nichols, Druitt was in Dorset playing cricket. On the day of Chapman's murder, he played cricket in Blackheath, and the day after the murders of Stride and Eddowes, he was in the West Country defending a client in a court case. While writers Cullen and Andrew Spallek argue that Druitt had the time and opportunity to travel by train between London and his cricket and legal engagements, or use his city chambers as a base from which to commit the murders, others dismiss that as "improbable". Many experts believe that the killer was local to Whitechapel, whereas Druitt lived miles away on the other side
