Hi,
It looks like the correct death.
The Times 5th December, 1935
DEATH OF SECOND VICTIM
Scotland Yard detectives yesterday continued the search for a man whom they wish to interview in connextion with the death of a woman who was found stabbed in a flat at Elmhurst Mansions, Elmhurst Street, Clapham, on Monday night, after a birthday party given for a 13 year old girl. Arthur Brooks, who was also found injured died in Weir Hospital last night.
At the opening of the inquest on the body of the woman yesterday her name was stated to be Eva Porter, but she had also been known as Eva Markwick and Eveline McGinty. The inquest was adjourned until December 18.
There was then a bit more about the man they were looking for.
I will have a further look.
Regards,
Mo
