The card was a riot of color, a grinning cartoon cat clutching a balloon that read "Happy Birthday!" Eleanor snorted with amusement. She usually got bills and the occasional flyer for dental work. She glanced around, as if expecting to see a hidden camera. No one. This was delightfully strange.

She skipped back inside, the card held high like a trophy. Her fingers fairly itched to know who had done this. The mystery was a tiny, delicious puzzle.

Suddenly, she had the most absurd notion. She grabbed a marker and added a tiny mustache to the cat. Then, a monocle. A tiny, ridiculous monocle.
