"Alarm System One" by Mike Pihlman
Tom is a dog lover. He lives in a nice part of town which, unfortunately, has seen its share of burglaries in the past few years.
Tom’s chihuahua is his primary alarm system. Whenever anyone comes within 100 feet of his house, alarm system one is activated and the barking commences.
One day, a particularly brave burglar, not afraid of dogs, broke into Tom’s house with alarm system one fully engaged and barking.
As Burglar was kneeling down to break into the safe he felt a presence from above, breathing, and a low rumbling growl.
Alarm System Two.
