As a detective solving the mystery of the crossword clue “Moves quickly, as a cloud,” I started by trying to think of words related to clouds that might fit the description. Ideas such as “zips” and “puffs” came to mind, but they didn’t seem to fit perfectly. I then remembered the word “scud,” which means to move quickly and with little effort, often in a low and erratic way. This seemed to be a more fitting word for the clue, and upon further research, I learned that “scud” is actually a meteorological term used to describe low, fast-moving clouds. This connection solidified my answer of “SCUDS” as the solution to the crossword clue. It’s thrilling to use my skills of observation and puzzle-solving to unravel a mystery like this.
