Home and Away confirms suspicious death in dark story

Major Home and Away spoilers follow from Thursday's Australian episodes (October 6), which some UK viewers may prefer to avoid.

Home and Away has revealed that Heather Fraser could be a secret killer.

The alarming revelation aired in Thursday's triple bill of episodes in Australia, which saw the ongoing Heather story come to a head in high-stakes scenes.

Heather has spent several weeks manipulating her long-lost mother Marilyn Chambers and trying to turn her loved ones against her.

In the big finale to the storyline, Heather lured Marilyn, Alf Stewart, Roo Stewart, Leah Patterson and Irene Roberts to a grand mansion as part of an outrageous revenge plan.

Heather isolated Marilyn by tying her to a chair in an upstairs room. In a twisted move, she set up a TV screen for Marilyn to watch what was happening to her friends in the dining room downstairs.

Heather then spiked the drinks of Alf, Roo, Leah and Irene and caused them to pass out at the table, allowing her to tie them up too.

Once everyone had regained consciousness again, Heather brought Marilyn downstairs and forced her to come clean over abandoning her when she was a baby.

Heather expressed bitter resentment over how Marilyn's decision had left her to be brought up by an uncaring father and stepmother.

Back in the Bay, local police officers Cash Newman and Rose Delaney became involved in the troubling situation when Justin Morgan became suspicious over the Summer Bay favourites all being missing.

Cash and Rose investigated the situation with help from wider police contacts, who found a dead body in the home of Heather's stepmum.

Rose explained: "They haven't found an ID yet, but it's looking like it was Heather's mother – or stepmother, whoever she was.

"The body was found in a chest freezer, so it's not going to be natural causes."

The initial findings showed that the woman had been dead for a while – with the murder likely to have been committed by Heather before she moved to the Bay.

Heather's father had also passed away a few months ago, but his death was from natural causes.

Back at the mansion, Alf was left in a precarious position when his spiked drink aggravated his heart condition, which led to difficulty breathing.

Heather spitefully refused to let anyone call an ambulance for Alf, clearly desperate for Marilyn and her friends to suffer as much as possible.

Fortunately, police were soon on the scene to rescue Alf, Roo, Leah and Irene from the dining room.

Heather wasn't finished with Marilyn yet and bundled her off to an upstairs balcony, dragging her onto the edge. However, Heather was finally stopped in her tracks when she lost her footing and fell.

Heather survived without serious injuries, but was devastated when a traumatised Marilyn cut all ties with her at the hospital. Will she now be brought to justice for her many crimes?
