If you enjoy solving brain teasers, here is the king of puzzles to test your mettle. Cryptograms, the deciphering of messages in code, are more fun-and more exciting-than solving cross word puzzles. Secret Writing is an authoritative popular work for the beginner as well as the advanced enthusiast, explaining the principles underlying the construction and deciphering of all types of cryptograms, ciphers and codes in use today. Numerous problems and teasers are presented, and the key to their solution suggested. More than a pastime book, the author relates the dramatic story behind many of the codes which are divulged. Cryptograms have long been used in peace and war. They are today in universal use in conveying secret intelligence. Here is a fascinating pastime, and one that is all at once leaping into popularity, which offers the puzzle enthusiast many hours of absorbing fun. Secret Writing was published in 1936. The author was a long-time editor and writer for pulp magazines and contributed a cryptography column to The Shadow magazine.
