"If he came," said Marco, "it was because he wanted to see it."

When they had finished talking, it was time for Marco and The Rat to go on their way. Loristan had given The Rat an errand. At a certain hour he was to present himself at a certain shop and receive a package.

"Let him do it alone," Loristan said to Marco. "He will be better pleased. His desire is to feel that he is trusted to do things alone."

So they parted at a street corner, Marco to walk back to No. 7 Philibert Place, The Rat to execute his commission. Marco turned into one of the better streets, through which he often passed on his way home. It was not a fashionable quarter, but it contained some respectable houses in whose windows here and there were to be seen neat cards bearing the word "Apartments," which meant that the owner of the house would let to lodgers his drawing-room or sitting-room suite.

As Marco walked up the street, he saw some one come out of the door of one of the houses and walk quickly and lightly down the pavement. It was a young woman wearing an elegant though quiet dress, and a hat which looked as if it had been bought in Paris or Vienna. She had, in fact, a slightly foreign air, and it was this, indeed, which made Marco look at her long enough to see that she was also a graceful and lovely person. He wondered what her nationality was. Even at some yards' distance he could see that she had long dark eyes and a curved mouth which seemed to be smiling to itself. He thought she might be Spanish or Italian.

He was trying to decide which of the two countries she belonged to, as she drew near to him, but quite suddenly the curved mouth ceased smiling as her foot seemed to catch in a break in the pavement, and she so lost her balance that she would have fallen if he had not leaped forward and caught her.

She was light and slender, and he was a strong lad and managed to steady her. An expression of sharp momentary anguish crossed her face.

"I hope you are not hurt," Marco said.

She bit her lip and clutched his shoulder very hard with her slim hand.

"I have twisted my ankle," she answered. "I am afraid I have twisted it badly. Thank you for saving me. I should have had a bad fall."
