Alice de Janzé, née Silverthorne, also known as Alice de Trafford and holder of the noble title Comtesse de Janzé for a few years, was an American heiress who spent years in Kenya as a member of the Happy Valley set of colonials. She was connected with numerous scandals, including the attempted murder of her lover in 1927, and the 1941 murder of The 22nd Earl of Erroll in Kenya. Her tempestuous life was marked by promiscuity, drug abuse and several suicide attempts. Growing up in Chicago and New York, Silverthorne was one of the most prominent American socialites of her time; a relative of the powerful Armour family, she was a multi-millionaire heiress. She entered French aristocracy in the early 1920s, when she married Count de Janzé. In the mid-1920s, she was introduced to the infamous Happy Valley set, a community of white expatriates in East Africa, notorious for their hedonistic lifestyle. In 1927, she made international news when she shot her lover in a Paris railway station and then turned the gun on herself; they both survived. De Janze stood trial but was only fined a small amount, and was later pardoned by the French state. She further scandalized the public by marrying, and then later divorcing, the man she shot.
