People greet Ros as she walks down the street in a way that you'd never get in my neighbourhood.

It's clearly a tight-knit community, which is why I think what happened to the Hemmings family business was all the more shocking.

Because people in this working-class Welsh village aren't particularly well-off, and they certainly weren't well-off in 2008.

£600 was quite a bit of money to go missing.

So up the road here is the bank.

Right.

So how often would Sally take this walk to the bank do you think?

I would think when there was any quantity of cheques to pay in.

Sally Walker had been given the cash, but she hadn't paid it into the business account.

So the bank manager suggested they take a closer look at what was being paid in and out of Martin's business over the last few months.

Thousands of pounds had been taken out of the business in forged cheques.

And there was only one suspect.

The bookkeeper, Sally Walker.

Martin's new solicitor suggests this is serious enough that Martin needs to go to the authorities.

When Sally shows up at his office offering to pay back the missing £9,000, Martin accepts the money and he tells the police the losses have been made good.

But that's not the end of the story, because the missing £9,000 was from the last few months.

What about before that?

Sally had worked for the Hemmings for around seven years.

So every evening after work, Martin and Ros would sit together at the kitchen table late into the night looking through years of financial ledgers.

And eventually, as Ros remembers it, they worked out that £64,000 had been taken out of Martin's business.
