I was really pleased to hold your letter in my hands. It smells like vanilla perfume ought to smell.

I'm sorry I did not answer immediately. I was fascinated by the book. Its title is The Picture of Dorian Gray. Do you know it?  

What’s the price of eternal youth? Handsome Dorian Gray has found the secret of eternal youth.Basil painted a beautiful picture of Dorian and gives it to him, and to date that painting is among his best work. As those around him age, Gray remains young and beautiful. A key example of Gothic horror fiction, The Picture of Dorian Gray is Oscar Wilde’s only novel and a classic of modern literature.But Gray has another secret – in his attic he hides a portrait of himself. While his own body remains fit and healthy, the image in the portrait becomes older and 
more ugly. Dorian is overcome with a deep feeling of sadness when he realizes that the painting will always be young and beautiful, while he will age. “How sad it is! I shall grow old, and horrible, and dreadful. But this picture will remain always young.If it were only the other way! If it were I who was to be always young, and the picture was to grow old! For that – for that –I would give everything! I would give my soul!” This was the beginning of the end for Dorian. As a writer Oscar Wilde has never gone out of fashion and, indeed, is probably now as popular as ever. 

What is powerful about this book is the clever dialogue, after reading it  made me want to know a lot more about Oscar Wilde. You may be interested in movie version, however, the book will be the best because you involve your own imagination.
This book is worth to head a list "must read".
 
That's all for today. I need to finish this letter because I was called  for help. Write me and I'll be glad to hold your letter in my hands again.
