It's a double mystery: two young men have vanished, and the investigation leads to two troubling clues in two different locations.
As Inspector Banks and his team scramble for answers, the inquiry takes an even darker turn when a truck careens off an icy road in a freak hailstorm. In the wreckage, rescuers find the driver, who was killed on impact, as well as another corpse . . . that of someone who was dead well before the crash.
