"But he had been with you some years," Barbara expostulated, for the boy had confided that fact to her.

"He had, but he had degenerated, we found."

A dreadful doubt seized Barbara that his dismissal might be due to the help he had given her in Alice's escape, and in that case she would be partly responsible for him.

"Will you kindly give me his address?" she said, turning back again to the office. The woman looked doubtful, and said she was not sure if she had it.

"I think if he has been with you several years, you must surely know where he lives," Barbara persisted; and seeing her determined look, the woman apparently thought it would be the quickest way to get rid of her, and did as she was asked. Barbara repeated the name of the street and the number once or twice as she went out, and wondered how she should begin to find her way there, though consoling herself by thinking it was not the first time she had hunted up unknown addresses successfully since she had come to France.

It was very hot, and for a moment she hesitated, wondering whether she would not put off her search till another time; then she decided it was her duty to look the boy up at once. Asking a kindly postman if he could direct her to the address, she found that the house was in one of the streets near the quays. Though rather a long way off, it was not difficult to find, and once found it was not easily forgotten, for the smells were mingled and many.

Barbara wandered down between the high old houses, looking at the numbers—when she could see them—and finally found the one she sought. She had not to wait long after knocking, and the door was opened by the bath-boy himself, who stared at her in astonishment.

"Ma'm'selle?" he said doubtfully, as if uncertain whether she were a messenger of ill omen or not.

"I have come to call," Barbara explained. "May I please come in?"

His face broadened into the familiar grin, and he shuffled down the passage before her, wearing the same heelless list slippers that had first attracted Barbara's attention to him in the bath-house. The room he took her into smelt fresh and clean, and indeed was half full of clean clothes of all descriptions.
