Moon-to-Earth radio is still on the drawing boards, the only way we can get through is to send Monroe back with the ship. If we do, we run the risk of having our garrison force, Tom and me, captured while he's making the return trip. In that case, their side winds up in possession of important information concerning our personnel and equipment, while our side has only the bare knowledge that somebody or something else has a base on the Moon. So our primary need is more information. "Therefore, I suggest that I sit in the dome on one end of a telephone hookup with Tom, who will sit in the ship, his hand over the firing button, ready to blast off for Earth the moment he gets the order from me. Monroe will take the single-seater down to the Riphaen Mountains, landing as close to the other dome as he thinks safe. He will then proceed the rest of the way on foot, doing the best scouting job he can in a spacesuit. "He will not use his radio, except for agreed-upon nonsense syllables to designate landing the single-seater, coming upon the dome by foot, and warning me to tell Tom to take off. If he's captured, remembering that the first purpose of a scout is acquiring and transmitting knowledge of the enemy, he will snap his suit radio on full volume and pass on as much data as time and the enemy's reflexes permit. How does that sound to you?" They both nodded. As far as they were concerned, the command decision had been made. But I was sitting under two inches of sweat. "One question," Tom said. "Why did you pick Monroe for the scout?" "I was afraid you'd ask that," I told him. "We're three extremely unathletic Ph.D.s who have been in the Army since we finished our schooling. There isn't too much choice. But I remembered that Monroe is half Indian—Arapahoe, isn't it, Monroe?—and I'm hoping blood will tell." "Only trouble, Colonel," Monroe said slowly as he rose, "is that I'm one-fourth Indian and even that.... Didn't I ever tell you that my great-grandfather was the only Arapahoe scout who was with Custer at the Little Big Horn? He'd been positive Sitting Bull was miles away. However, I'll do my best. And if I heroically don't come back, would you please persuade the Security Officer of our section to clear my name for use in the history books? Under the circumstances, I think it's the least he could do." I promised to do my best, of course. After he took off, I sat in the dome over the telephone
