Rainy autumn morning in Washington.

In his office, John was sitting with his feet up on a desk strewn with papers. He spent the whole night at the bureau, and was terribly tired.

The door opened and his partner entered, which made the man look up from the papers.

"Oh? It's you? I have a new crazy case.."

He sighed and leaned back in his chair.

"Don't laugh, but it's crop circles."
