Query: Lucid and detailed introduction

This is a really lucid and detailed introduction to derivative pricing theory from the pde way of doing things. The author is an applied mathematician, of the fluid mechanics variety, and this should tell you right away what the drift of the presentation is like.Some will argue that all of Wilmott's books are along exactly the same line, so why do we need another pde book? Given the amazing number of textbooks dedicated to the martingale approach, it is great to have yet another, fresh way of looking at the pde approach.The derivations come with all the necessary technical details, the style is very down to earth, and to my mind original. There are many details that I personally haven't seen in any other textbook before, and there are plenty of what seem like very useful exercises.I really like this book, and it was a pleasant surprise to see it in a local library.
