"Two strangers pass in the middle of the night on the street."


"One man looks at the other as the other looks at him. They exchange not a word, only a token from each of them to the other and the brush of hand as they pass."

"Sebastian, what is the point of this?"

"Please be patient, young master, and I will explain it."

"Fine, continue, then."

"No one else is around on the street to see them; it is completely deserted."
