When a United States Treasury Agent, detailed with investigating an arms deal between a Mexican cartel and a European far right group, goes missing in the swamps of southern Louisiana, FSI is soon on the case.
Jake and Mike are sent by Jordan Fletcher to investigate whether or not a mysterious new financier involved in the deal (known only as “The Broker”) is a part of Group 45 and responsible for the Agent’s disappearance.
With the help of an historian friend of Charlotte Kosior, they follow a trail that takes them back to the last days of the Confederacy, legends of a secret society, and infamous train robbers of long ago, as they hope to find answers on “The Pascagoula Run”.
