It's Not Unusual
We have been accused of theft. This is news to us but being assaulted in the market gets our attention. We head up to the house where the master of our accuser lives.
'You approach the house and see that the door... is open!'
'Is that unusual?'
'Not especially. You enter and quickly realise that the house... is silent!'
'...is that unusual?'
'Not really. You call out for Left Hand or his daughter but you get no reply.'
'...'
'That is peculiar.'
When the various levels of normality have been established we perform a rudimentary search of the building. A chest is found open, its lock clearly broken, and we realise that some books have been removed from it. At least we now know what we've been accused of and can work to clear our names.
