He gave in, laughing with me. "Remember where you were born?"
"On Samarra. I came here when I was three years old—my father was in Mapping and Exploring—" I stopped short, in shock. "He's dead!"
"Can you tell me your father's name?"
"Same as mine. Jay—Jason—" the flash of memory closed down in the middle of a word. It had been a good try, but it hadn't quite worked. The doctor said soothingly, "We're doing very well."
"You haven't told me anything," I accused. "Who are you? Why are you asking me all these questions?"
He pointed to a sign on his desk. I scowled and spelled out the letters. "Randall ... Forth ... Director ... Department ..." and Dr. Forth made a note. I said aloud, "It is—Doctor Forth, isn't it?"
"Don't you know?"
I looked down at myself, and shook my head. "Maybe I'm Doctor Forth," I said, noticing for the first time that I was also wearing a white coat with the caduceus emblem of Medical. But it had the wrong feel, as if I were dressed in somebody else's clothes. I was no doctor, was I? I pushed back one sleeve slightly, exposing a long, triangular scar under the cuff. Dr. Forth—by now I was sure he was Dr. Forth—followed the direction of my eyes.
"Where did you get the scar?"
"Knife fight. One of the bands of those-who-may-not-enter-cities caught us on the slopes, and we—" the memory thinned out again, and I said despairingly, "It's all confused! What's the matter? Why am I up on Medical? Have I had an accident? Amnesia?"
