It would require some fine tuning but you can use any group access extension and then assign ranks for reading one document, which will give you access to the other documents. Same as some websites where you have to post n articles before getting access to some restricted content.
Alternatively, link document C at the end of document B, which is linked from document A.
Hope that helps.
