Other forms: cover stories
A cover story can mean an account made up to hide the truth, but it can also mean an article that is featured on the front of a magazine to get attention.
Spies may use a cover story to hide their true identity so they can secretly operate and gather information. If you use the cover story of "my dog ate my homework" as an excuse for not turning in your assignment, you're not likely to convince anyone. In contrast, we can look forward to reading cover stories published in magazines each year about major events, important people, and top celebrities. These cover stories can be entertaining and informative, with nothing to hide.
