Cyber-Claus by William Gibson (The Washington Post Book World, 1991) is set in the near future and begins with a house AI detecting activity on the roof on Xmas Eve. The defences are activated and the owner prepares to confront the intruders.
This very brief piece ends (spoiler) with house AI identifying eight quadrupeds and one biped on the roof—and then the latter starts to come down the chimney . . . .
A lightweight squib.
