Are there any books written using dialogues? Last year I read Questions And Answers In School Physics. The book is based on a dialogue between a student and a teacher. A lot of concepts and ideas are seamlessly driven by the dialogue. I found the presentation to be lucid and pedagogical.
I am wondering if there is books with a similar style but for mathematics.

Donald Knuth's Surreal Numbers: How two ex-students turned on to pure mathematics and found total happiness  is an introduction to Conway's construction of real numbers as positions in certain two-player games.  It's very readable and it's written as a series of dialogues between the titular characters.
An unpublished French translation is available online.
