I read a book to earn this badge:
The Mysteries of Sherlock Holmes: Volume 1, by Arthur Conan Doyle
Sherlock Holmes is one of my favorite detectives to read about, because he is very smart and uses deductive reasoning and amazing logic to solve his variety of cases. This book includes many famous cases such as the Hound of the Baskervilles, A Study in Scarlet, The Sign of Four, and The Final Problem. I recommend this book to mystery lovers, because I'm sure you will love Holmes' way of solving cases.
