He seemed a very little boy to be carrying so large a butterfly net. He swung it in his chubby right fist as he walked, and at first glance you this particular little boy's whistling. Or, rather, there were two things peculiar, but each was related to the other. The first was that he was a Martian little boy. You could be very sure of that, for Earth little boys have earlobes while Martian little boys do not—and he most certainly didn't. The second was the tune he whistled—a somehow familiar tune, but one Back in those days, to be a colonist meant to be a rugged individual. And to be a rugged individual meant to not give a damn one way or another. And to not give a damn one way or another meant to make one hell of a mess on the placid face of Mars. There had not been any gold found, of course, and now, for the most part, the mining shacks so hastily thrown up were only fever scars of a sickness long gone and little remembered. A few of the houses were still occupied, like the one into which the Martian boy had just disappeared. So his instead, of something quite astonishing: How had it been possible for her to teach, and for him to whistle? All Martians are as tone-deaf as a bucket of lead. I went up three slab steps and rapped loudly on the weather-beaten door. didn't know you lived here and I don't know who you are. I'm not even interested in who you are. It's the little boy who just went in here that I was interested in. The little Martian boy, I mean." Her eyes spread as though somebody had put fingers on her lids at the outside corners and then cruelly jerked them apart. been bright, moist marbles glued above her cheeks. She said one word only: "Well?" "Nothing," I answered. "Except that Martians are supposed to be tone-deaf, aren't they? It's something lacking in their sense of hearing. So when I heard this little boy, and saw he was a Martian, and when he told me his mother perhaps, and more simply, it was her attitude in general. But whatever it was, I suddenly felt that, nosy or not, I was being treated shabbily. "I would like to speak to the Martian lady," I said. "There isn't any Martian lady." "There has and at the same time curiously defiant—as though she would dare me to whistle. And then—after what seemed to me a very long while—I slowly tumbled to what she meant. Her eyes were telling me that the little Martian boy wasn't a little Martian boy at all, that he was cross-breed, a little chap who had a Martian father and a human, Earthwoman mother. It was a startling thought, for there just aren't any such mixed marriages. Or at least I had thought there weren't. Physically, spiritually, mentally, or by any other standard you can think of, compared to a human male the Martian isn't anything you'd want around the house. I finally said: "So that is why he is able to whistle." "There isn't anything to be ashamed of," I said gently. "Back on Earth there's a lot of mixtures, you know. Some people even claim there's no such thing as a pure race. I don't know, but I guess we all started needed help. Lord knows the careworn look about her didn't show it was with the firewood problem, you give a woman a nice sharp axe and she complainingly: I nodded and took the card. As I left the office, I was thinking of something which struck me as somewhat more than odd. I had idly listened to a little half-breed Martian boy whistling part of the William Tell Overture, and it had led me to a wanted killer named Harry Smythe. I spent the remainder of the afternoon trying to get a lead on him and got nowhere. If he was hiding in any of the places I went to, then he was doing it with mirrors, for on Mars an Authority Card is the big stick than which there is no bigger. Not solely is it a warrant, it is more than a ghoul, you don't. Not finding him wasn't especially alarming. What was alarming, though, was not finding the Earthwoman and her little half-breed Martian son when I went back to the tumbledown shack where they lived. It was good-by. That night I went into the Great Northern desert to the Haremheb Reservation, where the Martians still try to act like Martians. It was Festival night, and when I got there they were doing the dance to the two moons. At times like this you want to leave the Martians alone. With that thought in mind, I pinned my Authority Card to my Martians dig a huge circular trench and fill it with dried roots of the belu tree and set fire to it. Being pitch-like, the gnarled fragments instant—before anyone observed me—I stood motionless and watched the sinuously undulating movements, and I thought, as I have often thought before, that this is the one thing the Martians can still do beautifully. Which, in a sad sort of way, is a commentary on the way things have gone since the first rocket-blasting ship set down on these "Wahanhk," he said. I watched him slip away. Wahanhk is an old Martian. I don't think any Martian before him has ever lived so long—and doubtless none after him will, either. His leathery, almost purple-black skin was rough and had a charred look about it, and up around the eyes were little plaits and folds that had the appearance of being done deliberately by a Martian sand-artist. the planet for such pitifully thin streams of water. "I'm looking for an Earthwoman," I said. "This particular Earthwoman took a Martian for a husband." "That is impossible," he grunted bitterly. "I would have said so, too," I agreed. "Until this afternoon, that is." "I met her little son," I went on. "A little semi-human boy with Martian features. Or, if you want to turn it around and look at the other side, a little Martian boy who whistles." His teeth went together with a snap. I nodded and smiled. "You know who I'm talking about." "Why?" had. The point is that he knows the woman. It follows, naturally, that last word. I nodded. "For murder." "Murder." He spat the word. "But not for the murder of a Martian, eh? Martians are not that important any more." His old eyes hated me with an intensity I didn't relish. "You said that, old man, not I." He only looked at me for another dull instant and then his eyes slowly closed and his hands folded together in his lap. Being caught in a lie only bores a Martian. I got up and went out of the tent. The woman never heard me approach. Her eyes were toward the flaming I ignored that. "Why did you pull out of that shack? I told you you had If that meant anything to her, I couldn't tell. In the flickering light from the fires, subtle changes in expression weren't easily detected. "Why should I care about an Earthman? My husband was a Martian. And he's dead, see? Dead. Just a Martian. Not fit for anything, like all Martians. Just a bum who fell in love with an Earthwoman and had the guts to marry her. Do you understand? So somebody murdered him for it. Ain't that pretty? Ain't that something to make you throw back your her man. small, thin shoulders. And I knew then the reason for old Wahanhk's bitterness when he had said to me, "But not for the murder of a Martian, eh? Martians are not that important any more." What I said then probably sounded as weak as it really was: "I'm sorry,
