The injured builder who moves to Florida in Stephen King’s novel Duma Key is named Edgar.
Edgar Freemantle is a successful Minnesota construction contractor whose life changes after a severe workplace accident leaves him with major injuries and a damaged marriage. He relocates to Duma Key, an island off Florida’s Gulf Coast, hoping that distance and painting will help him recover.
Edgar’s artwork soon appears to influence reality, linking his creative ability to the island’s buried supernatural history. The novel was published in 2008 and combines psychological recovery, friendship, family trauma, and supernatural horror.
Wireman is another important character, serving as Edgar’s companion and caretaker, but he is not the injured builder. The full protagonist’s name is Edgar Freemantle.
