Background information
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. 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". An excerpt was published in the May 16, 2014 issue of Entertainment Weekly.

Plot
The driver of a Mercedes S class plows into the crowd of people at a job fair, killing eight and severely injuring many. The Mercedes has been stolen from a woman named Olivia Trelawny, who later kills herself out of guilt. Bill Hodges, a recently retired detective from the local police department, receives a letter from an individual claiming to be the culprit, referring to himself as "Mr. Mercedes". Hodges is divorced, lonely and fed up with his life, occasionally considering suicide. The letter intrigues Hodges, who investigates the case instead of turning the letter over to his former police colleague, Pete Huntley.
Brady Hartsfield, the man behind the job fair massacre, is an emotionally disturbed psychopath who lost his father at age eight. When he was a young boy, he killed his mentally handicapped brother at the prompting of his alcoholic mother, with whom he has an incestuous relationship. Brady works in an electronics store and sells ice-cream from a truck as his second job. Riding in the truck enables him to observe Hodges and his neighbors, among them seventeen-year-old Jerome Robinson, who does small chores for Hodges.
Hodges meets Janey Trelawny, who is Olivia's sister, who hires him to investigate her suicide and the theft of the Mercedes. Hodges and Janey soon begin dating. Hodges finds out, with the help of computer-savvy Jerome, how Mr. Mercedes stole the car and drove Olivia (whom he made contact with through his job at the electronics shop) to suicide by leaving eerie sound files on her computer that were set to go off at unpredictable intervals, which escalated her feelings of guilt. 
At the funeral of Janey and Olivia's recently deceased mother, Hodges meets Janey's unpleasant relatives, among them her emotionally unstable cousin Holly. After the funeral, Brady watches as Hodges' car rolls towards the church. He mistakenly thinks Hodges is behind the wheel, when in fact it is Janey. As the car approaches Holly and Hodges, Brady remotely blows up the car, killing Janey. Hodges feels remorse but becomes even more eager to solve the case without the help of the police. Holly joins Hodges and Jerome in the investigation.
Brady accidentally kills his mother with a poisoned hamburger, which he had prepared for Jerome's dog. With her rotting body in their house, he plans to commit suicide by blowing himself up at a concert using explosives hidden inside a wheelchair. Jerome, Hodges and Holly manage to uncover Brady's real identity and search his computer. They eventually deduce that Brady's plan and rush to the concert venue to stop him. Hodges begins to suffer a heart attack and is unable to venture into the concert, but urges Holly and Jerome to press on. Holly locates Brady and delivers several harsh blows to his head using Hodges's "Happy Slapper" – a sock filled with ball bearings. Brady is left bleeding and comatose.
Hodges (who had been saved by concert staff), Holly and Jerome have a picnic to discuss the recent events. Hodges has learned that he will not be criminally charged for his actions regarding the Mr. Mercedes investigation. Holly and Jerome have received medals from the city, congratulating them on their work. Meanwhile, Brady awakens from his coma and asks to see his mother.

Reception
Mr. Mercedes received positive reviews, with many critics responding well to the book being different from King's "standard horror stories" and being a "compelling crime novel." It received a 4.07/5 score on Goodreads, dropping to 3.87 as of 19 January with 43,562 ratings  and a 4/5 on Barnes & Noble.Michael Marshall Smith of The Guardian noted the novel "is firmly positioned in suspense-thriller territory and the non-supernatural world – somewhere King evidently feels increasingly at home. … At its heart, Mr Mercedes is a traditional cat-and-mouse story about a psychopathic killer and the renegade cop who makes it his mission to bring him down." Considering three levels of evaluation – quality per se, expectations of King's "readers who return for his distinctively unstoppable storytelling engine, his particular and hugely dependable voice", and rules of "whichever genre" King increasingly departs to, he sums up: "Good book? Hell, yes. Good Stephen King book? Absolutely." Brian Truitt of USA Today gave the novel 3 and 1/2 stars: "With an accidental gumshoe and a freaky serial killer, … Mr. Mercedes takes the old detective genre in an excellent, modern direction". He commended "a fascinating look at what makes a serial killer in a post-9/11 context", adding that King also "really succeeds with Hodges' companions". Sheryll Connelly of The New York Daily News stated the novel is "telling a story that could almost be characterized as sweet except of course for the sociopath on a bloody rampage. King will be King, and he’s never less than scary. Who in their right mind would want him to be?" and noted that this is one of his books where instead of it being "horrific, King expresses outright tenderness and it’s evident here."Tasha Robinson of The A.V. Club was more reserved, writing that the novel opens with its best moment and "sags significantly in the middle, but it barrels toward a memorable conclusion … his tense, propulsive, ultra-fast-paced climax here seems like it was written with the movie in mind". Her main complaint was "a collection of laughably creaky old tropes at the center … a halfhearted stop at Señor Lazy’s Bargain Cliché Bin … predictable King-isms … a cutout character following a well-worn path". But she praised the novel for being "unusual in its dedication to surprising readers" and found it "a major step up from his previous book, Doctor Sleep".

Adaptation
In January 2015, it was announced that Mr. Mercedes would be turned into a limited television series. David E. Kelley was slated to write the project and Jack Bender would direct. Kelley and Stephen King serve as executive producers. On October 10, 2017, the Audience network announced that the series would be renewed for season 2, and conclude the story from the original Mr. Mercedes novel.  The third season was broadcast between September and November 2019.
