An old man shuffled down the side-walk with the aid of his cane, glancing up occasionally to peer at a shop window through his spectacles.
Then he stopped.
He sniffed at the air, turning his head this way and that. Shooting a glance over to a second hand bric-a-brac shop, he turned on his heel, marched there.
Standing at the open doorway, he smiled at the elderly female shop assistant within as a deep, bestial growl rumbled from within his chest.
Grinning, the tip of her tongue protruding from between her teeth, she responded with a growl of her own.
