Mac has been scrounging for cases. Business hasn't been good.

Thirteen-year-old Josh has hired him to find his coin collection for the princely sum of $25.

He's in the middle of that nearly pro bono case when Sophie, his on-again, currently off-again girlfriend, comes to him with a problem. Her best friend, Central Coast Network News reporter Linda Carmody, hasn't been heard from in over a week.

Completely out of character.

Mac's investigation uncovers a financial conspiracy that threatens to topple the government and exposes him to a level of physical danger he hasn't encountered in years.
