About the article "Assassination of Abraham Lincoln", section "Mudd's culpability".

Candidate passages:
The book begins with the story of Arabella "Bella" Getchel, who was taken hostage by John Wilkes Booth, the assassin of former President Abraham Lincoln, during the assassination at Ford Theatre itself.
Wilkes, in the book's second chapter, mentions that he likes to be called by his last name.
The book continually switches between the two stories, as Bella builds a friendship with a character named Steven and Wilkes.
The friendship between Wilkes and Bella was merely a trap so he could get her to look for him in the theatre, where he locks her in a closet so she cannot stop him from assassinating the President. 
Peter Taltavull (1825 – April 8, 1881) played a minor role in the events surrounding the assassination of Abraham Lincoln.
John Wilkes Booth stopped at Taltavull's Star Saloon just before going to Ford's Theatre next door and assassinating President Abraham Lincoln. 
Booth was born near Bel Air, Maryland, into the English American theatrical Booth family.
He was the illegitimate son of another famous actor, Junius Brutus Booth, an Englishman, who named Edwin after Edwin Forrest and Thomas Flynn, two of Junius' colleagues.
He was the older brother of John Wilkes Booth, assassin of President Abraham Lincoln.
Nora Titone, in her book "My Thoughts Be Bloody", recounts how the shame and ambition of Junius Brutus Booth's three illegitimate actor sons, Junius Brutus Booth, Jr. (who never achieved the stage stardom of his two younger actor brothers), Edwin Booth, and John Wilkes Booth, spurred them to strive, as rivals, for achievement and acclaim—Edwin, a Unionist, and John Wilkes, the assassin of Abraham Lincoln. 
Montréal's status as a major inland port with direct connections to Britain and France made it a valuable asset for both sides of the American Civil War.
While Confederate troops secured arms and supplies from the friendly British, Union soldiers and agents spied on their activity while similarly arranging for weapons shipments from France.
John Wilkes Booth spent some time in Montréal prior to assassinating President Lincoln, and in one case was said to have drunkenly gallivanted throughout the city telling anyone who would listen of his plan to kill Lincoln.
Almost all took him to be a fool.
After the War, President of the Confederacy Jefferson Davis stayed at a manor house located at the current site of The Bay on Sainte-Catherine's Street West; a plaque commemorating the site was installed on the West wall of the building, on Union Avenue, in 1957 by the United Daughters of the Confederacy. 
On April 12, 1865, after hearing the news that Robert E. Lee had surrendered at Appomattox Court House, Booth told Louis J. Weichmann, a friend of John Surratt, and a boarder at Mary Surratt's house, that he was done with the stage and that the only play he wanted to present henceforth was "Venice Preserv'd".
Weichmann did not understand the reference: "Venice Preserv'd" is about an assassination plot.
With the Union Army's capture of Richmond and Lee's surrender, Booth's scheme to kidnap Lincoln was no longer feasible, and he changed his goal to assassination.
The previous day, Booth was in the crowd outside the White House when Lincoln gave an impromptu speech from his window.
When Lincoln stated that he was in favor of granting suffrage to the former slaves, Booth declared that it would be the last speech Lincoln would ever make.
On the morning of Good Friday, April 14, 1865, Booth went to Ford's Theatre to get his mail; while there he was told by John Ford's brother that President and Mrs. Lincoln accompanied by Gen. and Mrs. Ulysses S. Grant would be attending the play "Our American Cousin" at Ford's Theatre that evening.
He immediately set about making plans for the assassination, which included making arrangements with livery stable owner James W. Pumphrey for a getaway horse, and an escape route.
Booth informed Powell, Herold, and Atzerodt of his intention to kill Lincoln.
He assigned Powell to assassinate Secretary of State William H. Seward and Atzerodt to assassinate Vice President Andrew Johnson.
Herold would assist in their escape into Virginia.
By targeting Lincoln and his two immediate successors to the presidency, Booth seems to have intended to decapitate the Union government and throw it into a state of panic and confusion.
The possibility of assassinating the Union Army's commanding general as well was foiled when Grant declined the theatre invitation at his wife's insistence.
Instead, the Grants departed Washington by train that evening for a visit to relatives in New Jersey.
Booth had hoped that the assassinations would create sufficient chaos within the Union that the Confederate government could reorganize and continue the war if one Confederate army remained in the field or, that failing, to avenge the South's defeat.
In his 2005 analysis of Lincoln's assassination, Thomas Goodrich wrote,"All the elements in Booth's nature came together at once – his hatred of tyranny, his love of liberty, his passion for the stage, his sense of drama, and his lifelong quest to become immortal.
"As a famous and popular actor who had frequently performed at Ford's Theatre, and who was well known to its owner, John T. Ford, Booth had free access to all parts of the theater, even having his mail sent there.
By boring a spyhole into the door of the presidential box earlier that day, the assassin could check that his intended victim had made it to the play and observe the box's occupants.
That evening, at around 10 p.m., as the play progressed, John Wilkes Booth slipped into Lincoln's box and shot him in the back of the head with a .44 caliber Derringer.
Booth's escape was almost thwarted by Major Henry Rathbone, who was present in the Presidential box with Mrs. Mary Todd Lincoln.
Booth stabbed Rathbone when the startled officer lunged at him.
Rathbone's fiancée, Clara Harris, who was also present in the box, was unhurt.
Booth then jumped from the President's box to the stage, where he raised his knife and shouted ""Sic semper tyrannis"" (Latin for "Thus always to tyrants," attributed to Brutus at Caesar's assassination and the Virginia state motto), while others said he added, "I have done it, the South is avenged!"
Various accounts state that Booth injured his leg when his spur snagged a decorative U.S. Treasury Guard flag while leaping to the stage.
Historian Michael W. Kauffman questioned this legend in his book, "American Brutus: John Wilkes Booth and the Lincoln Conspiracies", writing in 2004 that eyewitness accounts of Booth's hurried stage exit made it unlikely that his leg was broken then.
Kauffman contends that Booth was injured later that night during his flight to escape when his horse tripped and fell on him, calling Booth's claim to the contrary an exaggeration to portray his own actions as heroic.
Booth was the only one of the assassins to succeed.
Powell was able to stab Seward, who was bedridden as a result of an earlier carriage accident; although badly wounded, Seward survived.
Atzerodt lost his nerve and spent the evening drinking; he never made an attempt on Johnson's life.
