Cain hates the color gold, so he buries it in the garden.

Years later, he hears scraping noises coming from the garden. It's too dark to see what's going on, but there's a flash of something bright and gold in the darkness. Cain goes back to sleep.

In the morning, the lawn is covered with unearthed corpses, and Cain is furious. It's going to take forever to bury them all again, and his mansion smells like rot. At least the coin is gone. Cain's got enough curses of his own without hoarding someone else's.
