CourageKatz fanfic Youd

by Clipchip

There was no sound for miles. No wind to rustle the curtains or make that creaky windmill outside spin. No cars rushing down the road by the house. No creaking from the stairs or the attic. No truck engines backfiring…no pots clanking….No one yelling at the TV….No one cooking in the kitchen. Muriel and Eustace were gone.
