Devon Arvol returns to solve the mystery of a train that suddenly appears in a small town with all passengers missing. Instead of the important scientists and researchers, the train is filled with strange symbols painted in pure gold. But what's haunting Devon is not so much the missing passengers, but a child's bloody tennis shoe that hangs in the engineering compartment.
The Agency returns to solve a mystery only to stumble onto an ancient civilization that not only worships their Gods but lives with them. Return with Devon Arvol and meet new agents and old as they work together to save each other while fighting evil corruption at its core.
