The Gerritsen mansion, built in Red Hook in 1847, stands covered by scaffolding and plastic tarps in its slow metamorphosis into condominiums. A capable construction crew has the goodwill of neighbors. But when the day’s work ends, something stirs in the darkness. Soft voices whisper. Weird footprints linger. Children of Red Hook have begun to vanish. Delta Green takes an interest. The Gerritsen mansion did not always have that name.

Your Agents must investigate the three most recent disappearances and strange reports from the Gerritsen mansion. If some unnatural horror is at work, they must find a way to stop it. The moon darkens. Fears gather. The infants of Red Hook are hardly the only ones at risk.
