Arthur Morris was the last of three children to die after his stepmother, Martha Rendell, began swabbing their throats with hydrochloric acid at the family home in East Perth, Perth. His two sisters had died the previous year from the same treatment, disguised as a cure for diphtheria. Arthur, 15, suffered for months before he finally succumbed in 1908.
A doctor who had treated the boy, suspicious of the family’s string of throat deaths, requested an autopsy. The first examination found nothing to tie Rendell to the deaths, and she would remain free a while longer before the full truth of her method finally emerged.
