The murder of a Mary Todd Lincoln impersonator, Blanche, is found dead near Liv's first ladies/the White House dollhouse store. The mystery is like a cozy murder mystery combined with the National Treasure movies. There are two mysteries to solve, one being the murder and the other is locating the Lost Speech. Lincoln's "Lost Speech" was a speech given by Abraham Lincoln at the Bloomington Convention on May 29, 1856, in Bloomington, Illinois. Traditionally regarded as lost because it was so engaging that reporters neglected to take notes, the speech is believed to have been an impassioned condemnation of slavery.
