"Here are the sergents de ville!" cried a trembling waiter.
"He attacked me first," gasped Müller. "He has half strangled me."
"Qu'est ce que ça me fait!" shouted the enraged proprietor. "You are a couple of canaille! You have made a scandal in my Café. Sergents, arrest both these gentlemen!"
The police--there were two of them, with their big cocked hats on their heads and their long sabres by their sides--pushed through the circle of spectators. The first laid his hand on Müller's shoulder; the second was about to lay his hand on mine, but I drew back.
"Which is the other?" said he, looking round.
"Sacredie!" stammered the proprietor, "he was here--there--not a moment ago!"
"Diable!" said the sergent de ville, stroking his moustache, and staring fiercely about him. "Did no one see him go?"
There was a chorus of exclamations--a rush to the inner salon--to the door--to the street. But the stranger was nowhere in sight; and, which was still more incomprehensible, no one had seen him go!
"Mais, mon Dieu!" exclaimed the proprietor, mopping his head and face violently with his pocket-handkerchief, "was the man a ghost, that he should vanish into the air?"
