I agree with Laura.
The part of the sentence ' the butcher went to do the accounts into a room behind the shop. ' is wrong. The problem is the word 'into', which indicates movement.
There are two ways of correcting this. You can say either:
' the butcher went to do the accounts [in a room behind the shop.] '
' the butcher went into a room behind the shop [to do the accounts] '
In the first version, the main part of the sentence says what the butcher went to do, and the second part says where he did this.
In the second version, the main part of the sentence says where the butcher went, and the second part says why he went there.
Either of these sentences would be fine.
The other thing is that the seventh sentence should read 'One evening I started to help a woman from her bed to the place where she was to have an operation.'
