Research Methodology Book in the form of a dialogue between Professor and Student

I am looking for a research methodology book which is in the form of a dialogue between a professor and a student. Once I had this book and it is very helpful. Unfortunately, due to HDD problem, I lost it (it is in Pdf format, of course). I don't remeber its title, either. I would be very grateful to you if you remind me of the name of that book? Sorry if my question seems silly!
