It is 1718 and notorious pirate, Blackbeard is robbing merchant ships, confiscating their cargo, and even occasionally seizing ships. When Lieutenant Robert Maynard is enlisted by the governor of Virginia to find Blackbeard and kill him, a fierce battle ensues that leaves the pirate dead.

Nearly three hundred years later, the Pentagon asks private detectives Brad and Melanie Hicks to assist New Orleans police with a complex murder mystery. After the Hicks dock their boat in a marina north of the city, they have no idea what is in store for them over the next few weeks. As bloodless corpses begin appearing, others go missing, and the list of suspects remains empty, the police turn to local NCIS agents for help while Brad and Melanie visit an unscrupulous voodoo queen. After they follow her advice and end up in uncharted territory hundreds of miles from the French Quarter, the detectives are led to a mysterious encounter with Blackbeard and vampire activity that puts their lives in jeopardy. While winding through dark caves and mountains, the Hicks know that even if they manage to survive, this case may haunt them forever.

In this gripping mystery, two detectives become embroiled in a case that turns New Orleans upside down as a notorious pirate returns to find what he lost centuries earlier.
