I put two treat-size flakes in the fridge with the express intention of snaffling them on the sly and someone has eaten one of them - the house is awash with chocolate - I am blaming himself.
I don't mind sharing - it's the fact that there is a bin bag full of non-in-the-fridge chocolate (including five tins of Quality Street) and he eats one of the two tiny flakes that I put in the fridge.
Just so you all have a sound night's sleep, I have found it! It had fallen off the shelf into a door bit (where you keep jars of stuff that you use once and then chuck out when you can be arsed to sort the fridge out).
