Mr. Mercedes is an upcoming novel by Stephen King that the prolific author calls his first hard-boiled detective book. Scheduled for publication by Scribner on June 3, 2014, King shared the following about the book:
“I’m writing a crime novel about a retired policeman being taunted by a murderer with a working title Mr. Mercedes.”
The book was inspired by a true event about a woman driving her car into a McDonald’s restaurant. Originally meant to be a short story the tale grew into a 500 page suspense novel about a deranged terrorist with a bomb. King said he began writing the tome before the Boston Marathon bombing.
In an interview with Parade, published May 26, 2013, the author confirmed that the novel was “more or less” completed.
