 The book then states that in 1864, Baker uncovered the plans of Lincoln's future assassin, John Wilkes Booth, to kidnap Lincoln with the help of a different group of conspirators with different motives.The Stanton group, through Baker and Conness, supposedly provided Booth with money and information on Lincoln's movements.After several abortive attempts, Booth was ordered to halt his efforts in March 1865, and made no further attempts to kidnap Lincoln, but secretly resolved to murder him instead, the book alleges.
