Hills had a noble relative in Longsong Stronghold, Earl Luke Medde. Due to this he had a high position among patrol team.
Hills planned to sabotage Roland's plan to survive Months of Demons and decided to burn grain storage in lord's castle. He engaged in conspiracy all patrol members who weren't born in Border Town and wouldn't mind leave towners without food in the coming winter. In exchange for this all of them would get title of a knight and land to the east of Longsong Stronghold.
At night conspirators led by Brian infiltrated the castle through a tunnel. They were caught off guard when Brian and one of them jumped downstairs. In a clash Hills was wounded and wished to personally kill Brian, but was stopped by Nightingale.
Hills confessed to conspiracy and was sentenced to death.
