"Silence!" shrieked the commissary, into whose mind was intruding the consciousness that he had committed an outrageous blunder.

"What did you say your name was?" he demanded fiercely.

"I told you my name an hour ago," said his lordship haughtily, "and if you had not been so beastly clever you would have believed me. I am the Earl of Fairholme, a fact that can be readily substantiated by dozens of people here in Paris, and this is Mr. Reginald Brett, a friend of mine, who would have probably discovered the mystery of my friend's disappearance and the whereabouts of those diamonds by this time if you had not interfered."

His lordship was hardly coherent with annoyance, but the acute official had now convinced himself that a stupid mistake had been committed by his department.

He became apologetic and suave. He explained that their mysterious proceedings had to some extent committed them in the eyes of the police to secret knowledge of the crime which had so thoroughly aroused the detective departments in both London and Paris.

Evidently Scotland Yard had not advised the French police of Mr. Brett's official connection with the hunt for the murderers. The agents of the Paris Bureau had watched Brett's comings and goings during the day, and the detectives' suspicions, once aroused, were intensified when his friend, Lord Fairholme, sought the aid of two uniformed policemen to break in the door of the Turkish residents in the Rue Barbette.

Even now, politely concluded the commissary, he would regretfully be compelled to detain them for a little while, until he verified their statements. Meanwhile, they would not be subject to any further indignities, and might procure such refreshments as they desired. They would probably be set at liberty within a couple of hours.

At 1.30 a.m. Brett and Fairholme were ushered forth from the doors of the prefecture and stood in freedom in the street.

"Where now?" said Fairholme.

"To the hotel," replied Brett, wearily. "I must have sleep, so I consign the Turks, and the Sultan's diamonds, and every one concerned with the Albert Gate mystery, to perdition for the next eight hours."
