Dangerous Intimacy reveals how Mark Twain, after his wife's death, enjoyed the attentions of Isabel Lyon, his flirtatious and calculating secretary. With the help of Twain's assistant, Ralph Ashcroft, Lyon exiled Twain's daughter Jean, an epileptic, to a sanitarium and nearly succeeded in assuming complete control over Twain's household and estate. Based on the book by Karen Lystra and an unpublished Twain manuscript.
