In the winter of 1927, the U.S. Army organized the annihilation of a small port town off the coast of Massachusetts. Tales began to spread of human sacrifices to Eldritch gods, contracts with dark entities, and a battle between inhuman abominations.

A secret, much darker, remains off the coast, just beneath the cold waves. Now, a year later, New York Private Detective Robert Patrickson, a man haunted by war and alien memories not his own, uncovers a deadly conspiracy. In an off-the-map hotel near the coast, a woman is discovered, ritualistically murdered with a mysterious script drawn in blood etched on the walls.

It is the first clue hinting that the Shadow was never destroyed, could never be destroyed. It can only spread.
