(From the publisher):
Five men stole the million-dollar payroll; and their leader was an ex-Green Beret officer who had been thrown out of the army for having murdered too many civilians.
Pursuit flooded around them. But when a savage blizzard swept through the south-west states and all the computerised technologhy of the FBI was rendered useless, the burden of capture fell on one man - a Navajo cop who was forced to use all his Indian skills in tracking before he ran down the bandits and exacted retribution.
