"They tried to poison her—last Friday."

"They? Who?"

"I do not know. She went out for a walk. The poor woman was half dead, from nervous exhaustion and loss of sleep. She tells me that she stopped to get a cup of chocolate at a café in the Rue St. Honoré. After that she came back to the Champs Élysées, and sat upon a bench. She began suddenly to feel deathly ill, and, calling a cab, was driven home. When she arrived here, she was unconscious, and had to be carried to her room by the servants. She has been in bed ever since. I am glad to say, however, that she is better, and I think she could see you, by morning."

Grace left the Stapleton house, feeling somewhat baffled. The more she heard of this curious affair, the more inexplicable it seemed. She had hoped to visit the scene of the kidnapping, in company with the nurse, and examine the spot with her own eyes. This she now realized she could not do until the following day. She was walking in the direction of the Arc de Triomphe, revolving the affair in her mind, when a young man, evidently a Frenchman, of good appearance and not unpleasant face, came up beside her, bowed politely, and in excellent English asked her regarding Mary Lanahan.

"Miss Lanahan—is she better?" he inquired.

"Who are you, monsieur?" asked Grace, suppressing her inclination to resent the man's action, in her hope that she might learn something from him of value. His question showed Grace at once that he was acquainted with at least one member of the Stapleton household.

"I am a friend of Miss Lanahan's," the man replied. "I hear that she is ill. I saw you enter and leave the house, and I ventured to ask you if she is better."

"I was told that she is. I did not see her."

A peculiar expression crossed the young man's face; but Grace could not determine, so fleeting was it, whether it indicated pleasure or disappointment.

They walked along in silence for a few moments, and had almost reached the arch, when a ragged little urchin, a veritable Paris gamin, came up to Grace's companion and thrust a crumpled bit of paper into his hand, then darted off, whistling shrilly.
