The "Baltimore Plot" was an unsuccessful assassination attempt against 16th President of the United States Abraham Lincoln. Read in this informative book how the intelligence network of Pinkerton National Detective Agency spy Allan Pinkerton and his sidekick Female Detective Bureau operative Kate Warne launched an investigation into rumors circulating after the Nov. 1860 election of an impending southern secessionist sabotage of the Pennsylvania, Wilmington and Baltimore Railroad owned by Samuel Morse Felton Sr. After Samuel Morse Felton Sr. hired Pinkerton National Detective Agency to investigate these plausible threats, Allan Pinkerton discovered a plot of a secessionist secret society group known as Knights of the Golden Circle, led by Baltimore barber Cipriano Ferrandini, to assassinate Lincoln, who was on a 70 city train car railway tour from Springfield Illinois to Washington D.C., when Lincoln traveled by train through Baltimore and walked across town with his bodyguards from Baltimore's Calvert Street Station to the Camden Street Station on Feb. 23, 1861. The secessionists wanted to prevent Lincoln from being inaugurated in Washington D.C. on March 4, 1861 and wanted to install Vice President under President James Buchanan, John Breckenridge, as U.S. President.
