Alice de Janzé, née Silverthorne (28 September 1899 – 30 September 1941), also known as Alice de Trafford and known as Comtesse (Countess) de Janzé after her first marriage, was an American heiress who spent years in Kenya as a member of the Happy Valley set of colonials.
She was connected with several scandals, including the attempted murder of her lover in 1927, and the 1941 murder of the 22nd Earl of Erroll in Kenya.
Her 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 1921, when she married Count de Janzé.
In the mid-1920s, she was introduced to the 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 Raymond de Trafford in a Paris railway station and then turned the gun on herself; they both survived.
De Janzé stood trial and was fined a small amount, and later pardoned by the French state.
She went on to marry and later divorcing, the man she shot.
In 1941, she was one of several major suspects in the murder in Kenya of her friend and former lover Lord Erroll.
After several previous suicide attempts, she died of a self-inflicted gunshot in September 1941.
Her personality has been referenced both in fiction and non-fiction, most notably in the book White Mischief and its film adaptation, where she was portrayed by Sarah Miles.
