Neighbours' Holly Hoyland faces a major panic next week as she receives a threatening demand over Heath Royce's stolen money.

Holly realises that someone knows her secret as she's ordered to hand back Heath's dirty cash as soon as possible.

In recent weeks, Holly has been enjoying spending sprees with the money that Heath gained through criminal activity before he died.

Holly has found comfort through the various extravagant purchases, still traumatised following her ordeal in the Outback with Heath.

When Wendy Rodwell recently caught Holly with the money, Holly tricked her by giving a small amount back to the police and discreetly keeping the rest for herself.

As the story progresses next week, Holly's antics continue as she decides to use Heath's money to buy an overpriced car.

Holly isn't exactly discreet with her new purchase, so Wendy notices her latest expensive buy and becomes suspicious once again. Wendy airs her concerns with Holly's father Karl, leaving out the details of Heath's money.

Karl fears that Holly is behaving erratically through her trauma and he tries to raise the issue with her, but it ends badly.

A defiant Holly continues to focus on the car, but she's stopped in her tracks when she receives an anonymous text demanding the money back.

It's clear that someone close to Heath has rumbled Holly, so what will she do now? Has she placed her loved ones in danger?
