matter?" one of the Tindars asked. "Dr. Bronsky will be here presently, sirs," the attendant repeated. Dr. Bronsky came into the room with a retinue of flustered assistants. He nodded to the Tindars and worked his lips around as he waited for a pale little man to shuffle nervously into the room. "Now, Endicott, how did you move the cots around? Try to remember," the doctor spoke with a fatherly air to the little man. "I don't know ... I was thinking of something else," Endicott whined. "I was polishing the floors. They have to be cleaned by ten o'clock. I was working with the sterilizer on the floors. I moved the cots to get them out of my road. I thought they were identified." "Thought!" snorted Dr. Bronsky. "Since when does a damned fool think!" "I'm sorry, Dr. Bronsky," the little man pleaded. "It's a rule. The floors have to be cleaned."

We have no means in our power now to tell which of you is the duplicate and which is the original. We have one hope. Perhaps one of you woke up before you were removed from the chambers? Perhaps one of you remembers which chamber he was in?" "The last thing I recall is dozing off in the primary," one Tindar said. "Same here," the other said. "This is indeed regrettable!" boomed the doctor. "It's unheard of!" "It's not that serious, doctor," one of the Tindars said. "We can still do our work. One of us shall disappear on the way back, that's all. The only inconvenience shall be having to bring the duplicate part of the way back." "But who shall be your pilot?" the doctor mused, "if on the way back the one piloting the ship were to disappear...." "We have another
