To no purpose - Dr. Nelson had not seen the broadcast.  Yes, he had heard about it; no, he had no reason to think the broadcast had been faked.  Did Dr. Nelson know that an attempt had been made to coerce Valentine Smith into surrendering his rights to Mars under the Larkin Decision?  No, he did not know it, had no reason to believe so... and would not be interested if it were true; it was preposterous to talk about anyone "owning" Mars; Mars belonged to the Martians.  So?  Let's propose a hypothetical question, Doctor; if someone were trying to - but Dr. Nelson had switched off.  When Caxton tried to reconnect, a recorded voice stated sweetly: "The subscriber has voluntarily suspended service temporarily.  If you care to record-" Caxton switched off.
