The Beginning of the End of Martha Rendell

How an Unexpected Mother–Son Reunion Brought Down a Monster

On a seemingly ordinary day—1st May 1909—Sarah Morris was making her way to her West Perth home after a long day at work.

Suddenly, a young boy approached her. She didn’t recognise his face at first—until he revealed his name: George. He was her 14-year-old son.

Since April 1906, when a separation order had been granted, Sarah had not seen or heard from any of her five children—three girls and two boys. She had been ordered away from the family home. Early attempts to keep in touch only led to the children being beaten by their father, Arthur Morris. Not wanting to bring more harm upon them, she stayed away, believing her absence would spare them further misery.

Now, here stood George—clearly distressed, desperate, and begging for help.

He refused to return to his father’s East Perth home, where Arthur now lived with housekeeper-turned-mistress, Martha Rendell. George was adamant: he would rather sleep on the streets than go back if she would not help him.

What Sarah didn’t know was that three of her children had already died slow, agonising deaths under Martha’s so-called care in the intervening years. George was certain he would be next.

Shocked into action, Sarah went straight to the Perth Police Court and applied for custody of her son. Despite noting her past absence, the magistrate declared it “highly desirable” that the boy not be returned to his father’s custody. He refused to explain his decision in open court, only deepening the mystery.

Rumours quickly began to swirl through the streets of Perth. What was being hidden? What was really happening inside that East Perth home?

The reunion of mother and son proved to be the beginning of the end for Martha Rendell—a woman who would go down in Perth’s history as the very embodiment of the evil stepmother. Behind closed doors, she had slowly and methodically tortured her stepchildren to death under the guise of discipline and care.

Within a few months, the bodies of the deceased children were exhumed. The investigation that followed led to the arrest and trial of Arthur Morris and Martha Rendell. In court, overwhelming witness testimony and damning evidence led to Martha’s conviction and execution.

A desperate boy’s plea, delivered to his long-lost mother on a quiet Perth street, would spark the unravelling of one of Western Australia’s most notorious crimes.
