ELI5: Explain Like I'm 5

The Adventure of the Dancing Men

The Adventure of the Dancing Men is a story about a detective named Sherlock Holmes who is trying to solve a mystery. He is presented with a piece of paper containing a series of strange symbols which he later learns are called "dancing men."

Sherlock Holmes realizes that the symbols are actually a code that someone is using to communicate secretly. He spends a lot of time working out what the code means and eventually discovers that it's being used by a woman named Elsie Cubitt, who is in danger from her former husband who is trying to harm her.

The "dancing men" are actually a code that Elsie and her husband had made up when they were children. They'd use the code to write secret messages to each other. Elsie's husband had started using the code again, but in a different way. Instead of sending innocent messages, he was using it to threaten her.

Sherlock Holmes helps Elsie by figuring out what the code means and what her husband's messages were saying. He then arranges for Elsie to leave the country with her new husband to start a new life.

In the end, the mystery is solved, and the criminal is punished. Sherlock Holmes once again proves that he is a brilliant detective who can solve even the most complex cases.
