“Yes, Sylvia Elven ... I don’t know what she is—I know what she was—no, I don’t, either. I only know what Jarras says she was.”

Speed raised his eyebrows. “And what was that?”

“Actress, at the Odéon.”

“Never heard of her being at the Odéon,” he said.

“You heard of her as one of that group at La Trappe?”

“Yes.”

“Well, when I was looking for Buckhurst in Morsbronn, Jarras telegraphed me descriptions of the people 314 I was to arrest at La Trappe, and he mentioned her as Mademoiselle Sylvia Elven, lately of the Odéon.”

“That was a mistake,” said Speed. “What he meant to say was that she was lately a resident of the Odeonsplatz. He knew that. It must have been a telegraphic error.”

“How do you know?” I asked, surprised.

“Because I furnished Jarras with the data. It’s in her dossier.”
