attacker or even a pursuer. It was frightened, and, telepathically, in sharp bursting impressions, it pleaded with Roland. No! Oh, no! You do not understand. Wait! Wait and you can know of the countless facets of re— Something like pain shot through his skull. The Martian trembled, vibrated, and then—disappeared. Roland spun around. Frances stood there.
