The masters of short stories

In the lobby of the main library of the town is a shelf where you can leave your old books you don't have use for anymore and you can take books from there for free. There's not too often books I'm interested in but last week I found a real treasure. A collection of short stories, many of which have been written by some of the best/most famous writers in the literary history. I've liked the most stories so far a lot.

It's also sort of easy to read because the stories are short. If you have like half an hour spare time you can just grab the book and read maybe two stories and continue with the next story later.
