'Mrs McGinty's Dead' was the title of an Agatha Christie murder-mystery, but she had it published in 1952. No doubt she had read reports about the 'Flat Tragedy' in 1935. Why Eva chose the name we shall never know, and now there is doubt about the murderer. When I first read the report of the Coroner, I thought it was all very rushed and tied up. Stabbing oneself deep in the stomach, when there were only limited treatments (penicillin 1.6.46) as he would know as a registered chemist, is an odd way to prove one's false innocence. Was the later story about another man designed by the dying man to save Ruby? The lack of witnesses to another man is hardly conclusive, when there were only six flats to a staircase, presumably with the doors shut after 22:00 for privacy.
