The Complete Sherlock Holmes by Sir Arthur Conan Doyle. These books and short stories are fantastic and so much better than the movies. They also make a great quick read when you want to read something but don't have the time to get too invested. There are tons of short stories.
“Writing is perhaps the greatest of human inventions, binding together people who never knew each other, citizens of distant epochs. Books break the shackles of time. A book is a proof that humans are capable of magic.” Carl Sagan
