William Kent Krueger's Corcoran "Cork" O'Connor is part Irish and part Anishinaabe Indian. Prior to the first installment of the series, O'Connor worked as sheriff of Aurora, Minnesota. Before taking on his position as sheriff, he worked as a police officer on Chicago's South Side.
When the series begins, readers find O'Connor a relatively broken man, giving in to his vices of caffeine and nicotine. O'Connor is tormented by both the loss of his job and the subsequent breakdown of his marriage. Throughout the series, O'Connor takes on mysterious cases of murder and corruption. Using his own brand of detective work that relies not only on traditional investigatory skills, but also Native American techniques, O'Connor finds justice for victims of crime.
The first book in this series, "Iron Lake," was originally published in 1998. Krueger has continued releasing books in this series every one to three years. The most recent release as of May 2015, "Windigo Island," was released in 2014.
