Inch is a miniture detective (literally one inch tall) who often enlists the help of his niece Lori (sometimes written "Laurie"), her muscle-bound friend Gator, and their dog Braveheart to help solve mysteries. Their primary mode of transportation is the Hushmobile, a streamlined car that makes virtually no noise while being driven, making it perfect for following criminals unnoticed. The small Inch works for The Finkerton Detective Agency (a wordplay lampoon of The Pinkerton Detective Agency), where the boss (Mr. Finkerton) constantly dreams of the day that he will fire him.

Gator - Lori's friend.
