## 38. Eduard or Edwin?

This time, while strolling around the island, you accidentally come across an islander hopelessly stuck by the edge of a pond. No matter how hard you try, you can't pull him out of the mire. You remember that his name is either Edwin or Eduard, but you can't recall which. So you ask the islander what his name is, and you hear in response: “Eduard.”

What is the islander's name?

## B. KNIGHTS, LIARS, AND NORMAL PEOPLE

In another equally intriguing type of puzzle, the characters are divided into three types: knights, who always tell the truth, liars, who only lie, and normal people, who sometimes lie and sometimes tell the truth. Here are a few puzzles I've come up with about knights, liars, and normal people.
38. I must admit that in this task I allowed myself to play a trick on the reader. The key to the solution lies in the phrase that says that no matter how hard you tried, you couldn't "extract him from the mire." The words in quotation marks represent a pun - "extract his truths." From this, we can infer that the islander you met only spoke lies, that is, he was a liar. From this, we conclude that his name was Edwin.
