The Sapphire of Alternia
by JimGroovester
Problem Sleuth takes a job to find a stolen necklace for his highest profile client yet, but he quickly learns he's not alone in the hunt. Along the way to the Sapphire of Alternia, he fights gangs in black and green while the powers that be try to stop him. With little more than determination and a key in his pocket, he sets out into a city, a city that's trying to forget who it was, to find a piece of jewelry with far more to it than he could have ever known.
