In today's digital world, it's easier than ever to invade someone's life and far harder to escape.

Anyone, determined enough to do harm, can find a way to do harm.

I'm Carol Cadwalader, an investigative journalist.

In this podcast, I followed a story of Hannah, whose life was turned upside down by an anonymous stalker.

I no longer know who I can trust.

What began as one woman's nightmare became a chilling investigation into deception, control and the faceless power of the internet.

Stalked. Listen on BBC Sounds.

BBC Sounds, music, radio podcasts.

You're listening to Friday's episode of The Archers from BBC Radio 4.

Music Oh, there you are, love. Have you got your wallet with you?

Yeah? Why? Can you pay the nursery? My credit card's not working.

Busy pack of the veg boxes. Can't you use one of your other cards?

I've already tried. They're all maxed out.

What does that mean?

Well, I can't afford to pay the bill, Tom. What do you think it means?

Really? Well, cash flow's been a bit tight lately, for obvious reasons.

And we did say we'd pay for it out of our joint account, only someone never got round to old me. Tom? Hello? Are you in there?

Yeah, back here. Um, here, my cards are in there.

Oh, thanks. Oh, morning, Natasha.

Uh, hi, Linda. Are you here for the shop? Or to see your room?

Actually, I was after a quick word with Tom.

Oh, I'll leave you to it. I'll see you later, love. Nice to see you, Linda. Yeah, I'll catch you later. Bye.
