A Study in Scarlet One can get really clueless (pun intended) when asked to present such a famous writer. More so when the fame of the writer is even exceeded by his character: Sherlock Holmes. So there you go: no introduction, just grab the ebook and start diving into the smart world of the most famous detective with a magnifying glass. One more thing though: this book, A Study in Scarlet, is actually the birth certificate of both Sherlock Holmes and the magnifying glass as a research method. Enjoy!
