Whoof! The house vibrates as the front door closes.
Laughs in the living room; the clink of water glasses and the shush of water filling them from the tap.
Four sets of feet creak up the stairs; I hear the door handle twist.
Rustling, rummaging, sliding; a sharp 'clack' as a mysterious object is dropped on the floor.
Voices murmur through the thin wall.
More rustling, rattling and scraping...
The late night return of four adventurers...
Or is it a giant hamster?
