It starts a while back.
My daughter had "misplaced" both birthday money and Christmas money. Her room is a bit of a mess, and she's not terribly organised, so we just presumed she had lost it. 
However, to have lost so much money repeatedly just didn't quite ring true. It was almost a case of "you couldn't lose money that often even if you tried"
She was devastated and had no idea how it had gone missing. She swore she had known where it was, and that someone must have thrown it away. It's testament to what a lovely girl she is that she just accepted it and moved on.
She had saved it all up to spend on a birthday shopping trip.
There were four or five separate occasions and tranches of money. Even for the dippiest person in the world it seemed too unlikely. But I absolutely trusted our cleaner, I totally dismissed any thoughts that she might be involved.
Anyway, in the back of my mind I wondered if the cleaner had thrown it away, by accident, but I didn't want to say anything because obviously it would look like an accusation.
This morning, I had in my room an envelope with cash in, I thought I would just leave it out in my room to see if it was still there tonight. (£35
)
It's gone. The only people who have been in there are me, dh and the cleaner. He had also noticed the £35 this morning, and the same thought had crossed his mind.
He's now checked his wallet and £10 is missing from it.
We are really shocked. The cleaner had been really honest. Once her son took a cheap glass gem and she brought it back, with an apology.
We absolutely trusted her, but there are now too many occurrences to make sense.
What the hell do I do now? The cleaner has got our house keys. Do we need to change the locks before we alert her to the fact that we now know?
