Mary Lincoln and the Search for the Missing Lost Speech, is the second in the series.
Mary hid the speech that her husband gave in Bloomington, Ill, May, 1856. The Lost Speech so mesmerized the populace and reporter's, that no one transcribed it at the time. Abraham thought he'd thrown his copy away, but she saved it for prosterity.
The modern day characters search through archives at the Mary Todd Lincoln House, the Lincoln Library plus other well known landmarks.
Along the way, they will solve a murder or two.
