The world seemed brighter, somehow. The stark white walls of the hospital corridor lost their oppressive feel. Mark ran a hand through his hair, a goofy grin plastered on his face. He possessed the medical records of a very serious, very successful lawyer, who also happened to be, according to the files, terrified of clowns.

Mark imagined the lawyer, impeccably dressed, face-to-face with a red-nosed, oversized-shoe-wearing figure. The thought made him start humming a circus tune, and he began to whistle.

This was a situation ripe with possibilities.
