I want to create a document using book class. It should include several chapters and I desire to use a fancy style for it as I have seen some time ago in a book.
It had a special header printed on each page consisting on a continuous line which was interrupted some 1cm from the margin of the page by a box containing the page number.
Underneath this line the chapter number and the chapter title were displayed.
I think it was made using fancyhdr package and I have tried to make a *.tex file to reproduce this. I am no expert in LaTeX and I have managed only to create a box containing the pagenumber. I have tried to use \vspace in the header to lower this box and also the chapter name but with no results.
Does anybody know how it is possible to do it or has seen such a template?

Thank you so much.
