"Yes, I'm Security, but does it have to mean something?" I asked. "All I did was knock on your door."
"I heard it." Her lips were curled slightly at one corner.
I worked up a smile for her and let her see it for a few seconds before I answered: "As a matter of fact, I don't want to see you at all. I 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.
"Come in," she almost gasped.
I followed her. When I leaned back against the plain door, it closed protestingly. I looked around. It wasn't much of a room, but then you couldn't expect much of a room in a little ghost of a place like this. A few knickknacks of the locality stood about on two tables and a shelf, bits of rock with streak-veins of fused corundum; not bad if you like the appearance of squeezed blood.
There were two chairs and a large table intended to match the chairs, and a rough divan kind of thing made of discarded cratings which had probably been hauled here from the International Spaceport, ten miles to the West. In the back wall of the room was a doorway that led dimly to somewhere else in the house. Nowhere did I see the little boy. I looked once again at the woman.
"What about him?" she whispered.
Her eyes were still startled.
I smiled reassuringly. "Nothing, lady, nothing. I'm sorry I upset you. I was just being nosy is all, and that's the truth of it. You see, the little boy went by me a while ago and he was whistling. He whistles remarkably well. I asked him what the name of the tune was and he told me it was the 'Calm' from William Tell. He also told me his mother had taught him."
