During his Chancellor's Speaker Series talk at University of Massachusetts Lowell on December 7, 2012, King indicated that he was writing a crime novel about a retired policeman being taunted by a murderer. With a working title Mr. Mercedes and inspired by a true event about a woman driving her car into a McDonald's restaurant, it was originally meant to be a short story just a few pages long.[6] In an interview with Parade, published May 26, 2013, King confirmed that the novel was "more or less" completed.[7] Describing the novel for an interview with USA Today, published on September 18, 2013, King said that while it was started prior to the Boston Marathon bombings, Mr. Mercedes involves a terrorist plot which is "too creepily close for comfort".[8] An excerpt was published in the May 16, 2014 issue of Entertainment Weekly.[9]
