The fog-shrouded town of Innsmouth holds deep secrets. There are legends of inhuman creatures raised from the depths, of supernatural rites and elder gods from beyond. When Lamont Cranston and Margo Lane find themselves trapped in Innsmouth, terrible truths will surface ... truths only the Shadow can know.

Writer Ron Marz and artist Matthew Dow Smith tell a Shadow story like no other, placing the pulp avenger in H.P. Lovecraft's famous setting for a truly inspired one-shot that could only be called "The Shadow Over Innsmouth".
