Solving a crime is like piecing together a puzzle. But what happens if the pieces don't fit?

When police chief Gordon Hepler's doctor orders him to cut down on the stress in his life or risk losing his vision, Gordon books a winter retreat at a remote bed and breakfast. Hours away from Mapleton, where nobody knows he's a cop, he plans to relax and try to forget about his eyes.

However, traveling "incognito" doesn't mean he's left his cop instincts behind. His curiosity is piqued when one of the other guests at the B&B doesn't appear to be who she claims. Before he can explore the puzzle she presents, a man shows up, pleading for help. His car's gone off the road, and his wife is inside.

Although a blizzard is approaching, Gordon can't refuse the frantic man's request and agrees to help him search. Fighting the storm, Gordon and the man struggle down a ravine to the car. What they find turns out to be one more puzzle, and it's not the last Gordon faces.

Are they unrelated coincidences? Or part of one bigger mystery? Or is he seeing a crime where none exists? Well outside his jurisdiction, with his health at stake, Gordon wonders whether he should follow his cop impulses, or remember he's on vacation and let the locals handle it. When it becomes personal, Gordon has no choice.
