If cryptograms are your favorite type of puzzle, you will enjoy the 101 puzzles within Sherlock Holmes Puzzles: Code Breakers.
All are based on puzzles used in real life by emperors, spies, and warriors. Each puzzle has a task for Dr. Watson (you) to do. The brief stories and illustrations add a bit of whimsy to the book.
If you want to challenge yourself, look no further. Sherlock Holmes Puzzles: Code Breakers is a great choice to keep your mind active. 5 stars!
