This episode is the first part of the story of Daniel Sickle, a very unusual man that lived in the ninetieth century. In 1859 he shot and killed a man in front of the White House in Washington DC in front of several witnesses and got away with it. And it was only one of many adventures of the man called an American Scoundrel.
