The man ahead swore and flicked up an arm. "Red," he groaned. "By the infinite galaxies, this is the last straw!" He charged away, knocking Shano aside as he passed. Red signal. In bewildered anxiety Shano lifted the goggles from his eyes and stared into the sudden blackness. The red signal. Danger out there.
