"I thought—" she began.

"That your mistress was coming back?" Graham flashed.

There was no concealment in the girl's manner. It was certain that Maria was not in the apartment.

"You remember me?" Bobby asked.

"Yes. You have been here. You are a friend of mademoiselle's. You can, perhaps, tell me where she is."

Bobby shook his head. The girl spread her hands. She burst out excitedly:

"What is one to do? I have telephoned the theatre. There was no one there who knew anything at all, except that mademoiselle had not appeared at the performance last night."

Graham glanced at Bobby.

"When," he asked, "did you see her last?"

"It was before luncheon yesterday."
