Amid such contending interests, and in a free city so near to several frontiers, men came and went without attracting undesired attention. Each party suspected a new-comer of belonging to the other.

“He scrapes a fiddle,” Koch had explained to the inquiring fishwife. And perhaps he knew no more than this of Antoine Sebastian. Sebastian was poor. All the Frauengasse knew that. But the Frauengasse itself was poor, and no man in Dantzig was so foolish at this time as to admit that he had possessions.

This was, moreover, not the day of display or snobbery. The king of snobs, Louis XVI., had died to some purpose, for a wave of manliness had swept across human thought at the beginning of the century. The world has rarely been the poorer for the demise of a Bourbon.

The Frauengasse knew that Antoine Sebastian played the fiddle to gain his daily bread, while his two daughters taught dancing for that same safest and most satisfactory of all motives.

“But he holds his head so high!” once observed the stout and matter-of-fact daughter of a Councillor. “Why has he that grand manner?”

“Because he is a dancing-master,” replied Desiree with a grave assurance. “He does it so that you may copy him. Chin up. Oh! how fat you are.”

Desiree herself was slim enough and as yet only half grown. She did not dance so well as Mathilde, who moved through a quadrille with the air of a duchess, and threw into a polonaise or mazurka a quiet grace which was the envy and despair of her pupils. Mathilde was patient with the slow and heavy of foot, while Desiree told them bluntly that they were fat. Nevertheless, they were afraid of Mathilde, and only laughed at Desiree when she rushed angrily at them, and, seizing them by the arms, danced them round the room with the energy of despair.

Sebastian, who had an oddly judicial air, such as men acquire who are in authority, held the balance evenly between the sisters, and smiled apologetically over his fiddle towards the victim of Desiree's impetuosity.

“Yes,” he would reply to watching mothers, who tried to lead him to say that their daughter was the best dancer in the school: “Yes, Mathilde puts it into their heads, and Desiree shakes it down to their feet.”

In all matters of the household Desiree played a similar part. She was up early and still astir after nine o'clock at night, when the other houses in the Frauengasse were quiet, if there were work to do.
