The Duke nodded.

"And in Paris for the first time!" he remarked. "You mentioned the affair?"

"Yes! I took up an illustrated paper at a café on the night of my arrival whilst waiting for supper, and saw pictures of two men there who reminded me very much of the two whom I had seen on the railway near Pozen. I think I made some remark out loud which attracted the attention of a woman who was sitting at the next table, and later on I told her the whole story."

"And since then?"

"Since then I have told it to no one."

"Was there any one in the café you have spoken of who seemed to take any particular interest in you?"

Guy considered for a moment.

"There was a young lady from Vienna," he said, "who seemed to want to talk to me."

The two men exchanged glances.

"Madame has justified herself," the Duke murmured.
