Jonathan Hyde, the head cryptographer of the DOD facility, came storming in.
"What's the meaning of this, Andy? Could it be a fake? Have we tracked the source of the codes yet?"

It was the first time that Andy had seen his boss so rattled. The feeling was totally disconcerting but understandable, given the circumstances. He lifted his head from the computer monitor he was working at and, turning his head toward his boss, delivered some more bad news.

"I don't have the answer to those questions sir; however, I think we have another problem."

"What can be more problematic than what you've already told me?"

Andy showed him. Attached to each corner of the page with the initial strings of codes were more ciphers.

"This first one doesn't look so difficult," Hyde commented.

After a few minutes in his office Hyde came out holding a piece of paper with the solution for the first cipher. "It seems these guys have a flair for bad poetry. Let's start working on these other ciphers."

Taking the paper from Mr. Hyde, Andy smiled. It appeared the boss was back to his old confident self.
