Mr. Mercedes is the first novel in Stephen King's Bill Hodges trilogy, published in 2014. Written by the prolific horror and suspense master Stephen King, it marks a departure into crime fiction, earning widespread acclaim including the 2015 Edgar Award for Best Novel. The story centers on retired detective Bill Hodges, tormented by an unsolved case where a masked killer dubbed 'Mr. Mercedes' plowed a stolen luxury car into a crowd of job seekers, killing eight and injuring many more.
Hodges receives a taunting letter from the perpetrator, Brady Hartsfield, a disturbed young man with a dual life as a seemingly ordinary ice cream shop employee and tech-savvy sociopath. As Hodges embarks on an unauthorized investigation from his home, the narrative builds tension through psychological cat-and-mouse games, exploring themes of grief, revenge, mental illness, and the blurred line between justice and vigilantism. The novel's gripping pace, sharp characterizations, and King's signature blend of dark humor and horror elements solidified its status as a standout in his vast bibliography, launching a trilogy that delves deeper into Hodges' world.
