In the metropolitan mosaic that joins Dallas and Fort Worth together into a brightly lit metroplex, some mysterious figures still manage to keep to the shadows and slip through the cracks. Even after the Lake Worth Monster inspired a rash of phone calls to the Fort Worth Police Department, the "Goatman of Greer Island" faded back into the haze of myth. Is Lake Granbury's Ol' One Eye an impossibly large catfish or a sidetracked sea serpent? Could pterosaurs really coexist with the region's congested skies? From the Lady of White Rock Lake, to the Creature of Copper Canyon and the Chupacabras of Cedar Hill, Jason McLean methodically follows inexplicable events to their source and bizarre beasts to their lairs.
