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.
