Stephen King's crime novel is about Bill Hodges, a retired policeman being taunted by a murderer.  In the predawn hours, hundreds of unemployed men and women line up for the opening of a job fair.  Emerging from the fog, invisible until it is too late, a lone driver plows through the crowd in a stolen Mercedes, running over the innocent, backing  up, and charging again.  Eight people are killed; fifteen are wounded.  The killer escapes.  Mr. Mercedes is a war between good and evil from the master of suspense whose insight into the mind of this obsessed killer is unforgettable.
