On the last cold Sunday of February 1859 Daniel Sickles shot his wife's lover in Washington's Lafayette Square just across from the White House. This is the story of that killing and its repercussions. Charming and ambitious Dan Sickles literally got away with murder. His protector was none other than the President himself James Buchanan; his political friends quickly gathered around; and Sickles was acquitted. His trial is described with all Thomas Keneally's powers of dash and drama against a backdrop of double-dealing intrigue and slavery. Enslaved in her turn by the hypocrisy of nineteenth-century society his wife was shunned and thereafter banned from public life. Sickles meanwhile was free to accept favours and patronage. He raised a regiment for the Union and went on to become a general in the army rising to the rank of brigadier-general and commanding a flak at the Battle of Gettysburg - at which he lost a leg which he put into the military museum in Washington where he would take friends to visit it. Thomas Keneally brilliantly recreates an extraordinary period when women were punished for violating codes of society that did not bind men. And the caddish good-looking Dan Sickles personifies the extremes of the era: as a womaniser he introduced his favourite madam to Queen Victoria while his wife stayed at home and he installed his housekeeper as his mistress while his second wife took up residence nearby. American Scoundrel is the lens through which the reader can view history at a time when America was being torn apart.
