It's near the end of 1965 and Constable Cody Parker of Center Springs, Texas, has a frightening sense of gathering storm clouds. His dreams prove accurate when he is ambushed and nearly killed on a lonely country road during an unusually heavy snowfall. The attack leads locals to worry that a terrifying killer known as "The Skinner" has returned. As his nephew, Cody, recovers, Constable Ned Parker struggles to connect a seemingly unrelated series of murders, and the people of northeast Texas wonder why their once peaceful community has suddenly become a dangerous place to live. Investigating, Ned, Cody, and deputy John Washington cross paths with many colorful characters: cranky old Judge O.C. Rains; the jittery little farmer Isaac Reader; the Wilson boys, Ty Cobb and Jimmy Foxx; and a mysterious old man named Tom Bell. Of course, Ned's preteen grandchildren, Top and Pepper, are underfoot at every turn. When Cody follows his main suspect across the Rio Grande into Mexico, Ned understands that to save his nephew, he will have to cross more than a river: he will have to cross over to the right side of wrong.
