The Last Deal emphasis two important chapters in Special Agent Sam Little’s career. It walks the reader through the infant stages of his career culminating in a case that shows the emergence of the Mexican Cartels into various levels of illicit drug trafficking, most notable, methamphetamine, partnering with organized gangs in the U.S. In the second chapter, Agent Sam Little acquires a confidential informant that sets in motion his ability to infiltrate one of the U.S. cartel tentacles. The covert investigation into methamphetamine, human trafficking, and the transporting of massive amounts of dollars between the U.S. and Mexico’s Cartels, creates a milestone in both Agent Little and the confidential informant’s life. Mexico’s Cartels … their ruthlessness, violent demeanor, and how far they will go with this posture, was illustrated in an early 2019 Newsweek article, wherein they identified 33,000 murders occurred in Mexico. November of the same year, nine family members were killed, with their children shot in the back of their heads.The depth in which Agent Sam Little coordinates with his confidential informants and other law enforcement agencies while working undercover, demonstrates the intricacies of these cases. This often allows the emergence of memories relating to his Native American heritage to maintain a balance between work and family, often referred to as “walking through the looking glass.” Readers familiar with cross-cultural mystery novels will appreciate and identify with the authors experiences.
