Mr. Mercedes by Stephen King

In a high-suspense race against time, three of the most unlikely heroes Stephen King has ever created try to stop a lone killer from murdering thousands. 

The stolen Mercedes emerges from the pre-dawn fog and plows through a crowd of men and women in line for a job fair in a distressed American city. Then the lone driver backs up, charges again, and speeds off, leaving eight dead and more wounded.

The case goes unsolved and ex-cop Bill Hodges is out of hope when he gets a letter from a man who loved the feel of death under the Mercedes’s wheels… Brady Hartsfield wants that rush again, but this time, he’s going big, with an attack that would take down thousands—unless Hodges and two new unusual allies stop him.

“Mr. Mercedes is a rich, resonant, exceptionally readable accomplishment by a man who can write in whatever genre he chooses” (The Washington Post).
