During the 1920s Herbert O. Yardley was chief of the first peacetime cryptanalytic organization in the United States, the ancestor of today's National Security Agency. Funded by the U.S. Army and the Department of State and working out of New York, his small and highly secret unit succeeded in breaking the diplomatic codes of several nations, including Japan. The decrypts played a critical role in U.S. diplomacy. Despite its extraordinary successes, the Black Chamber, as it came to known, was disbanded in 1929. President Hoover's new Secretary of State Henry L. Stimson refused to continue its funding with the now-famous comment, "Gentlemen do not read other people's mail." In 1931 a disappointed Yardley caused a sensation when he published this book and revealed to the world exactly what his agency had done with the secret and illegal cooperation of nearly the entire American cable industry. These revelations and Yardley's right to publish them set into motion a conflict that continues to this day: the right to freedom of expression versus national security. In addition to offering an exposé on post-World War I cryptology, the book is filled with exciting stories and personalities.

The first novel in a brand-new alternate history series where Teddy Roosevelt is president for a second time right before WWI breaks out, and on his side is the Black Chamber, a secret spy network watching America's back. 1916. The Great War rages overseas, and the whole of Europe, Africa, and western Asia is falling to the Central Powers. To win a war that must be won, Teddy Roosevelt, once again the American president, turns to his top secret Black Chamber organization--and its cunning and deadly spy, Luz O'Malley Aróstegui.

She'll need every skill at her disposal to get him to trust her and lead her deep into enemy territory. In the mountains of Saxony, concealed from allied eyes, the German Reich's plans for keeping the U.S. from entering the conflict are revealed: the deployment of a new diabolical weapon upon the shores of America...

The second novel in an alternate history series where Teddy Roosevelt is president once more right before WWI breaks out, and on his side is the Black Chamber, a secret spy network watching America's back. After foiling a German plot to devastate America's coastal cities from Boston to Galveston, crack Black Chamber agent Luz O'Malley and budding technical genius Ciara Whelan go to California to recuperate. But their well-deserved rest is cut short by the discovery of a diabolical new weapon that could give the German Imperial Navy command of the North Sea. Luz and Ciara must go deep undercover and travel across a world at war, and live under false identities in Berlin itself to ferret out the project's secrets. Close on their trail is the dangerous German agent codenamed Imperial Sword, who is determined to get his revenge, and a band of assault-rifle equipped stormtroopers, led by the murderously efficient killer Ernst Röhm. From knife-and-pistol duels on airships to the horrors of the poison-gas factories to harrowing marine battles in the North Sea, the fight continues--with a world as the prize.

The Last Gasp takes us to the dark side of human history in the first full chronicle of the gas chamber in the United States. In page-turning detail, award-winning writer Scott Christianson tells a dreadful story that is full of surprising and provocative new findings. First constructed in Nevada in 1924, the gas chamber, a method of killing sealed off and removed from the sight and hearing of witnesses, was originally touted as a "humane" method of execution. Delving into science, war, industry, medicine, law, and politics, Christianson overturns this mythology for good. He exposes the sinister links between corporations looking for profit, the military, and the first uses of the gas chamber after World War I. He explores little-known connections between the gas chamber and the eugenics movement. Perhaps most controversially, he has unearthed new evidence about American and German collaboration in the production and lethal use of hydrogen cyanide and about Hitler’s adoption of gas chamber technology developed in the United States. More than a book about the death penalty, this compelling history ultimately reveals much about America’s values and power structures in the twentieth century.
