Dickson pressed her for more details and after initially hesitating, Elizabeth Buchanan confessed her fears that her eighty-four-year-old husband had killed himself at their home. This information prompted an immediate response from the policemen at the station; suicide was still a criminal offence and, along with the associated link with insanity, could carry a stigma for surviving relatives. 2 Dickson accompanied Elizabeth back to her house, and Farry followed a few minutes later. By the time they arrived, neighbours and other curious spectators had already gathered outside, evidently having heard of the incident. Dr James MacCullagh entered the house shortly thereafter, to examine what
