Book excerpt: X is the New York Times number 1 bestseller and thrilling, twenty-fourth book in the Kinsey Millhone Alphabet series from Sue Grafton. In hindsight, I marvel at how clueless I was . . . What I ask myself even now is whether I should have picked up the truth any faster than I did, which is to say not fast enough . . . When a glamorous red head wishes to locate the son she put up for adoption thirty-two years ago, it seems like an easy two hundred bucks for private investigator Kinsey Millhone. But when a cop tells her she was paid with marked bills, and Kinsey's client is nowhere to be found, it becomes apparent this mystery woman has something to hide. Riled, Kinsey won't stop until she's found out who fooled her and why. Meanwhile, the widow of the recently murdered P. I. – and Kinsey's old friend – Pete Wolinsky, needs help with her IRS audit. This seemingly innocuous task takes a treacherous turn when Kinsey finds a coded list amongst her friend's files. It soon leads her to an unhinged man with a catalogue of ruined lives left in his wake. And despite the devastation, there isn't a single conviction to his name. It seems this sociopath knows exactly how to cause chaos without leaving a trace. As Kinsey delves deeper into the investigation she quickly becomes the next target of this tormentor. But can Kinsey prove her case against him before she becomes the next victim?

Download or read book Codes Ciphers and Spies written by John F. Dooley and published by Springer. This book was released on 2016-03-31 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the United States declared war on Germany in April 1917, it was woefully unprepared to wage a modern war. Whereas their European counterparts already had three years of experience in using code and cipher systems in the war, American cryptologists had to help in the building of a military intelligence unit from scratch. This book relates the personal experiences of one such character, providing a uniquely American perspective on the Great War. It is a story of spies, coded letters, plots to blow up ships and munitions plants, secret inks, arms smuggling, treason, and desperate battlefield messages. Yet it all begins with a college English professor and Chaucer scholar named John Mathews Manly. In 1927, John Manly wrote a series of articles on his service in the Code and Cipher Section (MI-8) of the U.S. Army’s Military Intelligence Division (MID) during World War I. Published here for the first time, enhanced with references and annotations for additional context, these articles form the basis of an exciting exploration of American military intelligence and counter-espionage in 1917-1918. Illustrating the thoughts of prisoners of war, draftees, German spies, and ordinary Americans with secrets to hide, the messages deciphered by Manly provide a fascinating insight into the state of mind of a nation at war.

Book excerpt: “Dazzles from start to finish.” —Georgia Hunter, New York Times bestselling author of We Were the Lucky Ones Set against the backdrop of World War II, a sweeping, atmospheric novel of sacrifice, ambition, and commitment, and the secrets we keep from the ones we love It's 1927 when Alec and June meet as children in a tranquil English village. Alec, an orphan, anchors himself in the night sky and longs for adventures. June memorizes maps and railway timetables, imagining a future bright with possibilities. As the years pass, their loves feels inevitable, but soon the Second World War separates them. Alec enlists as a Royal Air Force pilot flying daredevil fighter sorties at night; June finds her calling as a codebreaker at Bletchley Park, covert work that will mean keeping her contribution to the war effort a secret from Alec forever. Each is following a dream—but those dreams force them apart for years at a time. Their postwar reunion is bittersweet: Alec, shot down and imprisoned in a series of POW camps, grapples with his injuries and the loss of his RAF career. June, on the other hand, has found her vocation and struggles to follow the expected path to domesticity, as much as she loves Alec. But Alec wants nothing more than to make a life and a family together. With the war behind them, their scars—both visible and unseen—make them strangers to each other. Now each must decide how much to reveal to the other, which dreams can be sacrificed, and which secrets are too big to bear alone. Spanning forty years and shifting from bustling Indian ports to vibrant gardens in Edinburgh to a horse farm in Kenya, The Stars We Share is a poignant, heart-wrenching novel about the decisions and concessions that make a life and a love worth having.

Download or read book The Woman Who Smashed Codes written by Jason Fagone and published by HarperCollins. This book was released on 2017-09-26 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: National Bestseller NPR Best Book of the Year “Not all superheroes wear capes, and Elizebeth Smith Friedman should be the subject of a future Wonder Woman movie.” —The New York Times Joining the ranks of Hidden Figures and In the Garden of Beasts, the incredible true story of the greatest codebreaking duo that ever lived, an American woman and her husband who invented the modern science of cryptology together and used it to confront the evils of their time, solving puzzles that unmasked Nazi spies and helped win World War II. In 1916, at the height of World War I, brilliant Shakespeare expert Elizebeth Smith went to work for an eccentric tycoon on his estate outside Chicago. The tycoon had close ties to the U.S. government, and he soon asked Elizebeth to apply her language skills to an exciting new venture: code-breaking. There she met the man who would become her husband, groundbreaking cryptologist William Friedman. Though she and Friedman are in many ways the "Adam and Eve" of the NSA, Elizebeth’s story, incredibly, has never been told. In The Woman Who Smashed Codes, Jason Fagone chronicles the life of this extraordinary woman, who played an integral role in our nation’s history for forty years. After World War I, Smith used her talents to catch gangsters and smugglers during Prohibition, then accepted a covert mission to discover and expose Nazi spy rings that were spreading like wildfire across South America, advancing ever closer to the United States. As World War II raged, Elizebeth fought a highly classified battle of wits against Hitler’s Reich, cracking multiple versions of the Enigma machine used by German spies. Meanwhile, inside an Army vault in Washington, William worked furiously to break Purple, the Japanese version of Enigma—and eventually succeeded, at a terrible cost to his personal life. Fagone unveils America’s code-breaking history through the prism of Smith’s life, bringing into focus the unforgettable events and colorful personalities that would help shape modern intelligence. Blending the lively pace and compelling detail that are the hallmarks of Erik Larson’s bestsellers with the atmosphere and intensity of The Imitation Game, The Woman Who Smashed Codes is page-turning popular history at its finest.
