The trail of the serpent

Stunned by the Japanese invasion of their island the colonists of Borneo have only one chance of escape - to reach the sea and hope a friendly passing vessel picks them up. For the fifty-odd survivors of the trek across the mountains, their savious appears in the form of an embittered atheist who is captain of the HENNY, a veteran salvage vessel. Captain Krasser agrees to help the desperate group on one condition - that the clergymen and nuns among them forsake their religion.
