"Mr. Mercedes" by Stephen King

I just finished "MR. Mercedes" and this is not a typical Stephen King book, is not a horror novel like most of his books, is more a detective thriller.
Brady Hartsfield killed 8 people and injuring many others by driving into a queue outside a job fair, was never caught. A few months later, in another part of town, a retired cop named Bill Hodges still haunted by unsolved crime receives an anonymous letter from someone who describes himself as the Mercedes killer, promising to kill again. Only Bill Hodges, with a couple of friends can apprehend the killer before he strikes again. And they have no time to lose, because Brady’s next mission, if it succeeds, will kill thousands of people. If Hodges and his crew be able to solve the puzzle and catch crazy killer? Or maybe Mr. Mercedes gonna kill them? Grab the book and find out by yourself.
I can't wait for the next book of this trilogy.
