I enjoy a good mystery - and when it involves a code to decipher - it just doubles the fun with two puzzles to solve in one story!
In the graphic novel mystery Sherlock Holmes and the Adventure of the Dancing Men, master detective Sherlock Holmes receives a picture of stick figures with their arms and legs positioned in different ways so it looks like they are dancing. The stick figures are appearing around the home of Mr. Cubitt who asks Sherlock Holmes if he can determine what the pictures mean. Holmes examines different samples of the drawings and believes they are a code used to communicate messages in secret. When Holmes travels to Mr. Cubitt's home to inform him of what he has learned, Holmes encounters another mystery: Mr. Cubitt has been murdered! Immediately, Holmes begins questioning the servants and looking for other clues that will reveal the identity of the murderer.
