Charles Vincent never saw his face at all. It is very dark in some of those clubs and the Coq Bleu is like the inside of a tomb. He went to the clubs only about once a month, sometimes after a show when he did not want to go home to bed, sometimes when he was just plain restless. Citizens of the more fortunate states may not know of the mysteries of the clubs. In Vincent's the only bars are beer bars, and only in the clubs can a person get a drink, and only members are admitted. It is true that even such a small club as the Coq Bleu had thirty thousand members, and at a dollar a year that is a nice sideline. The little numbered membership cards cost a penny each for the printing, and the member wrote in his own name. But he had to have a card--or a dollar for a card--to gain admittance. But there could be no entertainments in the clubs. There was nothing there but the little bar room in the near darkness. The man was there, and then he was not, and then he was there again. And always where he sat it was too dark to see his face. "I wonder," he said to Vincent (or to the bar at large, though there were no other customers and the bartender was asleep), "I wonder if you have ever read Zurbarin on the Relationship of Extradigitalism to Genius?" "I have never heard of the work nor of the man," said Vincent. "I doubt if either exists." "I am Zurbarin," said the man. Vincent hid his misshapen left thumb. Yet it could not have been noticed in that light, and he must have been crazy to believe there was any connection between it and the man's remark. It was not truly a double thumb. He was not an extradigital, nor was he a genius. "I refuse to become interested in you," said Vincent. "I am on the verge of leaving. I dislike waking the bartender, but I did want another drink." "Sooner done than said." "What is?" "Your glass is full." "It is? So it is. Is it a trick?" "Trick is the name for anything either too frivolous or too mystifying for us to comprehend. But on one long early morning of a month ago, you also could have done the trick, and nearly as well." "Could I have? How would you know about my long early morning--assuming there to have been such?" "I watched you for a while. Few others have the equipment to watch you with when you're in the aspect." So they were silent for some time, and Vincent watched the clock and was ready to go. "I wonder," said the man in the dark, "if you have read Schimmelpenninck on the Sexagintal and the Duodecimal in the Chaldee Mysteries?" "I have not and I doubt if anyone else has. I would guess that you are also Schimmelpenninck and that you have just made up the name on the spur of the moment." "I am Schimm, it is true, but I made up the name on the spur of a moment many years ago." "I am a little bored with you," said Vincent, "but I would appreciate it if you'd do your glass-filling trick once more." "I have just done so. And you are not bored; you are frightened."
