Narkom lifted a silencing hand and turned to move away where there would be less likelihood of anything they might say being overheard; for at that moment a voice had sounded and from a most unusual quarter. Unnoticed until now, a fisher’s boat, which for some time had been nearing the shore, swept under the packet’s stern and grazed along the stone front of the pier.

“Voila, m’sieur,” said, in French, the man who sailed it. “Have I not kept my word and brought your excellency across in safety and with speed?”

“Yes,” replied the passenger whom the fisher addressed. He spoke in perfect French, and with the smoothness of a man of the better class. “You have done well indeed. Also it was better than waiting about at Calais for the morning boat. I can now catch the very first train to London. Fast is she? There is your money. Adieu!”

Then came the sound of some one leaving the boat and scrambling up the water stairs, and hard on the heels of it the first whistle of the coming train. Narkom, glancing round, saw a slouching, ill-clad fellow whose appearance was in distinct contrast with his voice and manner of speaking, come into view upon the summit of the pier. His complexion was sallow, his matted hair seemed to have gone for years uncombed; a Turkish fez, dirty and discoloured, was on his head, and over his arm hung several bits of tapestry and shining stuff which betokened his calling as that of a seller of Oriental draperies.

This much Narkom saw and would have gone on his way, giving the fellow no second thought, but that a curious thing happened. Moving away toward the footpath which led from the pier to the town, the pedler caught sight suddenly of the man standing at the gangplank; he halted abruptly, looked round to make sure that no one was watching, then, without more ado, turned round suddenly on his heel, walked straightway to the gangplank and boarded the boat. The Mauravanian took not the slightest heed of him, nor he of the Mauravanian. Afterward, when the train had arrived, Narkom thought he knew why. For the present he was merely puzzled to understand why this dirty, greasy Oriental pedler who had been at the pains to cross the Channel in a fisher’s boat should do so for the apparent purpose of merely going back on the packet to Calais.

By this time the train had arrived, the pier was alive with people, porters were running back and forth with luggage, and there was bustle and confusion everywhere. Narkom looked along the length of the vessel to the teeming gangway. The Mauravanian was still there, alert as before, his fixed eyes keenly watching.

A crowd came stringing along, bags and bundles done up in gaudy handkerchiefs in their hands, laughing, jostling, jabbering together in low-class French.

“Here they are, guv’ner—the Apaches!” said Dollops in a whisper. “That’s the lot, sir. Keep your eye on them as they come aboard, and if they are with him—Crumbs! Not a sign; not a blessed one!” For the Apaches, stringing up the gangplank by twos and threes and coming within brushing distance of the waiting man, passed on as the Oriental pedler had passed on, taking no notice of him, nor he of them, nor yet of how, as they advanced, the pedler slouched forward and slipped into the thick of them.

“By James! one of them—that’s what the fellow is!” said Narkom, as he observed this. “If during the voyage the Mauravanian speaks to one man of the lot——”

He stopped and sucked in his breath and let the rest of the sentence go by default. For of a sudden there had come into sight upon the pier a dapper little French dandy, fuzzy of moustache, mincing of gait, with a flower in his buttonhole and a shining “topper” on his beautifully pomaded head; and it came upon Narkom with a shock of remembrance that he had seen this selfsame living fashion plate pass by Scotland Yard twice that very day!
