Is this a classic book?

Hi everyone,

I need your help!!
I've got an question from an teacher about this book.

The question is :
Why is this a classic story.
I must answer this question with 5 citations.

My first quote is :
"First published 1897
This edition published by Coppens & Frenks, Amsterdam" (Page 4)

My Second quote is :
"Will you get me some matches?" said the visitor, quite abruptly. "My pipe is out." ( Page 10 )

But i can't find more quotes of this "classic" story. And i realy don't know if this correctly what im doing.

Thanks in advance,
