"Only this—it was not our friend Talbot who came here on Tuesday with a lady."

"You are sure?"

"Positive. I have compared the handwriting in the hotel register with a letter undoubtedly written by Mr. Talbot, and the two do not agree. The entry 'Mr. and Mrs. Talbot, London,' in the visitors' book of the Grand Hotel, was a mere trick intended to amuse the police for a few hours until the conspirators had perfected their scheme for final and complete disappearance."

"It was a bold move."

"Very. Quite in keeping with the rest of the details of an uncommon crime."

"Here we are," said Gaultier with a laugh. "If we find Hussein-ul-Mulk at home I don't know what the deuce we are going to say to him. Remember that I depend on you to carry out a difficult situation, because my Turkish friend will become suspicious the minute he finds me dabbling in intrigue. He knows full well that such matters are quite outside of my usual business."

"I think I will be able to interest him," said Brett calmly; and without further preliminary Gaultier ascertained from the concierge that the Turkish gentleman was within.

The two men ascended to the second storey.
