Is it not possible (are the exact details of this known? I admit to not having kept up with every single bit of info) that Sally Walker perceives her ex boss as having stitched her up for something she wasn't truly responsible for?
That might explain why she has presented herself and Moth as victims who were 'taken advantage of' by a 'swindler'
Let's say the accounting was a mess, and some mistake was genuinely made and you were accused of being responsible for the total loss, but there wasn't any way in which you could prove yourself not to have done it. So you feel if it went to court it would just be 'he said, she said' what can you do in such a situation? Let's say you did genuine F up. But not deliberately.
So let's say to avoid the stress a possible record and because you care about the people you used to work for, you take a loan to just make it go away.
You then feel you lost your home unfairly
I have some experience working for a small family business, and I swore I would never work for a small business again. It is not like working for a big corp where you feel no obligation beyond doing your job and can take a day off sick without knowing everyone will struggle with you missing and the shortfall is deftly dealt with. No, it's like the business is their baby or child. The pressure can be more focused. If someone falls short there isn't necessarily a backup person to filter the mistake, and the impact can be massive! In this family business I worked for, all invoices were paid months and months late, whilst things were acquisitioned. I never did the accounting thank god, but I dread to think if I did.
It does just sound odd to have been responsible for something like that and have the raw nerve to put yourself in the spotlight where it could inevitably be dug up.
And you still can't prove you weren't responsible now when a journalist comes sniffing around.
