The speaker was a girl. She had red hair and green eyes. Otherwise there was no resemblance, though she too was pretty. But red hair and green eyes seemed to be haunting him. "What's that thing on your left wrist, then?" asked the girl spunkily. * * * * * Mikel reddened. Rule Five of the booklets he handed out with the tickets to all travelers leaped into his mind: "Remember, you cannot change the course of history. To avoid confusion and difficulty, avoid revealing to any person you meet in other time-periods the true nature of your presence there." He broke the rule, and was sorry at once. "It's a timeporter," he said, "set for my return home." The girl laughed. "That's a good one. I thought I'd heard everything since I came to this crazy place. What are you, an Arab, dressed in that tablecloth?" "I was born right here in Los," Mikel announced with dignity. "I've always lived here." "So they grow them crazy here right from the start! Then where's your home you're 'set' to return to?" "Here in Los." The girl stood up hastily, a look of alarm on her face. "Oh, please," Mikel cried, "don't go. I can explain. Perhaps you can help me." She sat down again dubiously. "Well, I'm a sucker for a good story," she said. "Shoot." "I--I wouldn't shoot. I have no weapon." That wasn't true--he did have a weapon: the knife. But he could hardly mention that. Anyway, the girl only laughed again. "Wisecracks, yet," she said unintelligibly. "Well, what's the story?" "I am from this place, but I am not from your time," Mikel began laboriously; he was utterly unaccustomed to social conversation with a woman. "I am from--with me it is 2839." "What in the--look, what are you advertising? Some science fiction magazine?" "I don't understand that word--adver--what is it? Please believe me. I shouldn't tell you, I'm breaking a rule. But it is true." "Go on." She fixed him with a skeptical glance. "I was--I am a ticket-seller for Time Travel Tours. This morning--I mean what was to me this morning--a customer was killed at my window." He plunged ahead. She listened in silence, a peculiar expression in her eyes. "So you see," he concluded, "I am here for a week. But then I go back--the timeporter will see to that. I _want_ to go--I'm sorry I ran away. But I'm sure the police will say I did it, because of the knife." "Let's see it." He brought it out. "Why, that's just an ordinary kitchen carving knife," she said, just as the man in the store had done. "I suppose you _would_ call it an antique in--what was it?--2839. I still say you're haywire--or else this is some new racket I don't get." "I don't understand."
