The same post in different single.php files

Hallo!

I can’t figure out following thing – I have multiple single.php files (depend on category) for each chapter of my site. And I have home chapter, where all the posts are displayed. Therefore every post should be displayed in different template depending from the place from where it is clicked.
For example, post from category media, when clicked in Media chapter, appears in Media template, but clicked in Home chapter, should appear in Home template.

Any suggestions?
Thanks in advance
