Diane strained her ears for possible re-transmission of the Niccola's signals, which would indicate the Plumie's willingness to try conversation. But she suddenly raised her hand and pointed to the radar-graph instrument. It repeated the positioning of dots which were stray meteoric matter in the space between worlds in this system. What had been a spot--the Plumie ship--was now a line of dots. Baird pressed the button.
"Radar reporting!" he said curtly. "The Plumie ship is heading for us. I'll have relative velocity in ten seconds."
He heard the skipper swear. Ten seconds later the Doppler measurement became possible. It said the Plumie plunged toward the Niccola at miles per second. In half a minute it was tens of miles per second. There was no re-transmission of signals. The Plumie ship had found itself discovered. Apparently it considered itself attacked. It flung itself into a headlong dash for the Niccola.
