"Seltz must be arrested at once," the Ambassador cried, in a rage.
"So far, monsieur, there is not the slightest evidence against him. Further, it is my opinion that he will leave London at once. Tell me the name of the shop in Piccadilly Circus where he was employed, and we will lose no further time in getting on his trail."
The Ambassador was not entirely certain of the location of the shop. He had never visited it. The name, he remembered, was given in the note as Perrier. The note had been delivered by one of the servants; he could tell where, and to whom he had delivered it.
Duvall recommended to the Ambassador that he report the murder to the police at once, but requested that no mention be made of the presence of himself and Monsieur Dufrenne. "We should be held as witnesses," he cautioned Monsieur de Grissac, "and that would seriously interfere with our plans. Let us interview the servant who took the letter at once."
The latter, a groom, was soon disposed of. He gave the number and location of the barber shop in Piccadilly Circus, a short distance away, and reported that he had handed the message to a dark, smooth-shaven man at the second chair. He did not know Seltz, but the proprietor had pointed him out in response to his inquiries. His description of the man was vague and unsatisfactory; he was unable to give any further information on the subject. Investigations as to anyone having made inquiries at the servants' entrance during the evening, regarding Noël, elicited the information that a heavily built, dark man, smooth-shaven, had called about half-past seven, and upon being informed that the valet was confined to his room and could not be seen, had disappeared. No one had taken any particular notice of his coming or going.
When the party had once more assembled in the reception-room, Duvall turned to Monsieur de Grissac. "There is nothing more to be accomplished here, monsieur," he remarked, quietly. "We will get after this fellow Seltz at once, and I trust that before long the missing snuff box will be returned to you."
The Ambassador shook hands with his guests, in a state of extreme agitation. "Lose no time," he urged. "You must recover the box before the thief has an opportunity to turn it over to those who are back of him, else it will be too late. I shall pray for your success." He stood at the door as his guests departed, shaking as though with a palsy. "It is a matter of greater moment than life itself. I trust you will not fail."
CHAPTER IV
Richard Duvall, accompanied by the silent little curio dealer, left the home of the French Ambassador and walked rapidly to the barber shop of Alphonse Perrier in Piccadilly Circus. They found the place without difficulty, a large and evidently prosperous establishment, located on the ground floor of a building, the upper rooms of which were devoted to business offices. A large plate glass window in front bore the sign, "Alphonse Perrier, Tonsorial Parlors."
