内容简介：
Something that was never meant to exist, now swims the murky depths of Swallowtail Lake. Rob Alva is the sheriff of Cornerstone Valley. After Marshal Bingham assaults an employee at EVI, he is arrested but later escapes. People are disappearing, and their vehicles turn up at the lake with bloodstains and strange markings inside. The bodies are never found. Is there a serial killer on the loose? Does the EVI complex hold the answer? What about the nightmarish creature that inhabits the lake? Is there a connection? Read Still Waters for the answers.
