When that first whine rose in the throat of a fellow worker and turned into a screaming, tearing dog-like howl, Nita van Sloan, laboring in a war factory, quickly summoned the Spider. … And the Spider found a city mad with terror, its population fighting each other to escape the death that turned humans into howling maniacs. … A grim, stark story with exciting, breath-taking action on every page — a story you will remember with startling clarity every time you hear a dog howl in the night . . . not a story for a faint-hearted reader!
