Was there an assassin on Grant's train?

[Gene C]

Not sure if Mary wrote this, or it was a conversation, but in Ruth Painter Randall's book, "Mary Lincoln Biography of a Marriage",
Mary became attached to her sister's grandson, Edward "Lewis" Baker Jr. She wrote several times to him.

From p393-394 of Randall's book, "She talked much of the past and of her lost sons. She told Lewis what had not been known before, that Lincoln was holding her hand when the fatal shot was fired. When death took two of Lewis's little sisters she wrote tenderly and understandingly of his sorrow: "We are never prepared for these things...God, gives us our beloved ones, we make them our idols, they are removed from us & we have patiently to await the time when He reunites us to them" Then followed perhaps the most poignant sentence in all her expressions of her own grief: "And the waiting, is so long!"
