In the summer of 1930, two federal prohibition agents were murdered. The first died in a hail of buckshot on a dark street in Aguilar, Colorado. Six weeks later, the second agent and his vehicle disappeared on a sunny afternoon along a New Mexico state highway south of Raton. These events occurred during the era when the government legislated a ban on alcohol manufacture, distribution, and sales within the United States. During their 50-year search, the authors sought answers to why no one was ever prosecuted for these crimes. This is the first book to correlate the two murders, identify how and why they occurred, name the parties involved and the roles they played.

The authors interviewed many individuals associated with the events and discovered a trove of National Archives files containing incident reports, suspect interview notes, the dead agents' daily activity logs and their personnel files. Building upon this base, they located the remaining documents generated by state and local law enforcement officers and additionally data mined private and public contemporary newspaper collections.

The shadows along the trail lift as the light of truth is shown upon this mystery. Two federal agents can now rest in peace.
