Constructor note:
The phrase “inner circle” was the inspiration for this puzzle. I just had one of those moments where I saw the phrase, and naturally thought that it could be the subject of a puzzle. I knew that I wanted a hidden word to reflect a circle. I decided to go with four-letter words, for some reason. My search yielded three candidates. It was not as easy as I thought to find words that can mean circle that are four letters long. But it did give me a break. I am always trying to make puzzles with five or six theme answers.
