Earl

Earl was a British citizen who lived in London around 1868.

Being an orphan, Earl spent most of his time with his friends on the street. One day, while shooting at a target with a revolver they had found, Earl became involved in the murder investigation of Louis Prescott. The Assassins Jacob and Evie Frye interrogated him briefly, but it soon became evident that his revolver had not been the murder weapon.
