We didn't understand what it was...

...but when it mercilessly killed the building 31 laboratory staff at Area 51, we knew we had to risk our lives to save yours.

In Contaminant, the fourth installment of The Palmdale Files, former agent Harold Anderson reveals the coverup of a deadly alien contaminant that killed some of the top scientific and medical minds at Area 51 and threatened the lives of everyone on base-and on the planet. If the people of the world discovered that we accidentally hid a deadly alien pathogen that could create a global pandemic, the governments of the world would have no way of stopping the biological invasion and the resulting chaos that would end human life as we knew it in the 1960s. Contaminant-also known as Event C-31 Alpha-is the fourth in a series of forgotten and buried events the author once destroyed to protect the peace and security of the United States-events the government would rather hide forever.

The Palmdale Files share highlights from Harold Anderson's U.S. Air Force career, where he worked to defend the nation and the world from paranoid hysteria about unexplained phenomena and threats from above.
