One of my favorite book it is adventure of Sherlock Holmes it have mystery, adventure, fight, secrecy, passion in work, friend relationship etc. & lot more things we learn from this book I personally suggest to read who love mysterious story & detective story to read. it cool I can say that only arthur conan doyle writer is famous for mysterious story writing it’s just cool, best to learn real world things which help to live life well by observing things & defending our self’s.
