Mr. Mercedes / Stephen King / 437 pages / April Challenge Rain

Brady Hartfield work two jobs.  He is a part of the Cyber Patrol at Discount Electronix and he drives an ice cream truck.  He was also responsible for the City Center Massacre, killing eighteen and injuring fifteen.  He engineered the suicide of the lady whose Mercedes he stole to effect the killing.  Now he is determined to do the same for retired detective Kermit William Hodges, who led the investigation to ferret out the "perk" - perpetrator.  Retirement has not been kind to Hodges.  He put on weight,  watched too much TV, and obsessed over his father's service revolver, but he is determined to catch Mr. Mercedes.  Mr. Mercedes is equally fixated on Hodges.  With two unlikely assistants, Bill attempts the near impossible.  As always with King, parts of this book are horrifically shocking.  Although it may not be one of his best, it is a memorable walk down memory lane with one very twisted villain and a hero determined to thwart him.
