Hi this is my second book! I am still on my old book but it took me a long time to figure out what cases I could do! Sherlock needs help on some cases are you smart enough to help him and be his next Watson? Just some codes you might want to help with! In need of help solving some these coded messages. Dr Watson left with Mary, now I need a new partner can you figure these out for me? -SH

The need to conceal the meaning of important messages has existed for thousands of years. Over time, people have found increasingly complex ways of encoding their messages as the simpler ways are decoded with greater ease. Contrary to layman-speak, codes and ciphers are not synonymous. A code is where each word in a message is replaced with a code word or symbol, whereas a cipher is where each letter in a message is replaced with a cipher letter or symbol. In fact, when most people say "code," they are actually referring to ciphers. Ancient scripts and languages have been understood using decoding and deciphering techniques, most famously the Rosetta Stone of Ancient Egypt. In fact, codes and ciphers have determined the outcome of politics and wars throughout history. There are thousands of types of hidden messages, but here we look at only ten as an overview. Several have examples for you to test yourself with. @seulyoon_park
