In December 1926, Agatha Christie goes missing. Investigators find her empty car on the edge of a deep, gloomy pond, the only clues some tire tracks nearby and a fur coat left in the car --- strange for a frigid night. Her husband and daughter have no knowledge of her whereabouts, and England unleashes an unprecedented manhunt to find the up-and-coming mystery author. Eleven days later, she reappears, just as mysteriously as she disappeared, claiming amnesia and providing no explanations for her time away. The puzzle of those missing 11 days has persisted. With her trademark exploration into the shadows of history, acclaimed author Marie Benedict brings us into the world of Agatha Christie, imagining why such a brilliant woman would find herself at the center of such a murky story.

In 1909, Clementine steps off a train with her new husband, Winston. An angry woman emerges from the crowd to attack, shoving him in the direction of an oncoming train. Just before he stumbles, Clementine grabs him by his suit jacket. This will not be the last time Clementine Churchill will save her husband. LADY CLEMENTINE is the ferocious story of the ambitious woman beside Winston Churchill, the story of a partner who did not flinch through the sweeping darkness of war, and who would not surrender either to expectations or to enemies.

She possessed a stunning beauty. She also possessed a stunning mind. Could the world handle both? Her beauty almost certainly saved her from the rising Nazi party and led to marriage with an Austrian arms dealer. Underestimated in everything else, she overheard the Third Reich's plans while at her husband's side, understanding more than anyone would guess. She devised a plan to flee in disguise from their castle, and the whirlwind escape landed her in Hollywood. She became Hedy Lamarr, screen star. But she kept a secret more shocking than her heritage or her marriage: she was a scientist. And she knew a few secrets about the enemy. She had an idea that might help the country fight the Nazis...if anyone would listen to her.

Clara Kelley is not the experienced Irish maid who was hired to work in one of Pittsburgh's grandest households. She's a poor farmer's daughter with nowhere to go and nothing in her pockets. But the other woman with the same name has vanished, and pretending to be her just might get Clara some money to send back home. Serving as a lady's maid in the household of Andrew Carnegie requires skills he doesn't have, answering to an icy mistress who rules her sons and her domain with an iron fist. What Clara does have is a strong resolve coupled with an uncanny understanding of business, and Andrew begins to rely on her. But Clara can't let her guard down, not even when Andrew becomes something more than an employer.
