Hi, I'm Allison Sandy from The Lady Vanishes.

While we're continuing with our investigations into Marion's case,

some of our team have been busy working on a new podcast

you may be interested in. It's called

pendulum. Here's a preview. She was a vibrant young woman with plenty of

friends, a daughter, a sister, a wife and a mom of two

small children. How did Margaret Kirstenfeld end up repeatedly stabbed with her throat slashed on her

neighbor's lawn in the tiny Queensland cane town of Serena.

Was it murder or suicide? Experts thought both.

And now the pendulum is swinging again.

It's been more than 40 years, could a killer still be on the run?

Finding answers for Margaret's loved ones and Mother before it's too late.

Pendulum, the podcast available now and don't forget another major

episode of the Lady Vanishes coming up on July 29.
