Joe DeMarco likes to call himself a troubleshooter. It sounds better than “bagman” or “fixer.” With more than a decade of troubleshooting under his belt on behalf of John Mahoney, the Speaker of the House, DeMarco has seen his fair share of dangerous situations.

When Andie Moore, a 23-year-old working in the DOJ’s Inspector General’s Office, is murdered in cold blood in Florida’s Everglades, it falls on DeMarco to get to the bottom of things. Paired with Emma, an enigmatic, retired ex-spy with seemingly endless connections in the military and intelligence communities, they venture south to the scene of Andie’s murder: Alligator Alley.

DeMarco and Emma waste no time in identifying a two suspects—a pair of crooked, near-retirement FBI agents named McIntyre and McGruder. But as they keep digging, it becomes clear that these FBI agents weren’t acting alone, and that this goes much deeper than just the murder of an innocent 23-year old woman.
