"She is five feet seven, has black hair, a nose with a high bridge, her eyebrows are black and almost meet across it, she has a pale olive skin and holds her head proudly."

"That is the one," Marco answered.

They were a week in Paris and each day passed this big house. There were certain hours when great ladies were more likely to go out and come in than they were at others. Marco knew this, and they managed to be within sight of the house or to pass it at these hours. For two days they saw no sign of the person they wished to see, but one morning the gates were thrown open and they saw flowers and palms being taken in.

"She has been away and is coming back," said Marco. The next day they passed three times—once at the hour when fashionable women drive out to do their shopping, once at the time when afternoon visiting is most likely to begin, and once when the streets were brilliant with lights and the carriages had begun to roll by to dinner-parties and theaters.

Then, as they stood at a little distance from the iron gates, a carriage drove through them and stopped before the big open door which was thrown open by two tall footmen in splendid livery.

"She is coming out," said The Rat.

They would be able to see her plainly when she came, because the lights over the entrance were so bright.

Marco slipped from under his coat sleeve a carefully made sketch.

He looked at it and The Rat looked at it.

A footman stood erect on each side of the open door. The footman who sat with the coachman had got down and was waiting by the carriage. Marco and The Rat glanced again with furtive haste at the sketch. A handsome woman appeared upon the threshold. She paused and gave some order to the footman who stood on the right. Then she came out in the full light and got into the carriage which drove out of the courtyard and quite near the place where the two boys waited.
