Petra and Kipp discover the truth about the Lincoln assassination while investigating the government's hanging of Mary Surratt in the time-travel adventure, A Conspiracy to Murder, by T.L.B. Wood
A flash of muzzle fire...a shot rings out...a president is dead...the fate of a nation is changed.
Assisted by a shadowy group of conspirators—ultimately executed by the government—John Wilkes Booth assassinated Abraham Lincoln.
Among the conspirators was Mary Surratt, who went to the hangman's scaffold along with three men.
But was Mary Surratt truly guilty, or did she possess a secret?
Petra, accompanied by her furry partner, Kipp, join forces with Peter and Elani to travel back in time to a war-torn nation to determine the truth. Their ability, due to their appearances as humans accompanied by their canine companions, allows them to go where others fear to tread.
But when they get too close, they risk becoming suspects of the conspirators as well...
