Sheard turned, and found that a deep-seated, heavily-cushioned chair, also antique, and which he had overlooked, stood close behind him. An odd perfume hung in the air.

"Ah," said Séverac Bablon, in his softly musical voice, "you have detected my vice."

He passed an ebony box to his visitor, containing cigarettes of a dark yellow colour. Sheard lighted one, and discovered it possessed a peculiar aromatic flavour, which he found very fascinating. Séverac Bablon watched him with a quizzical smile upon his wonderfully handsome face.

"I am afraid there is opium in them," he said.

Sheard started.

"Do not fear," laughed the other. "You cannot develop the vice, for these cigarettes are unobtainable in London. Their history serves to disprove the popular theory that the use of tobacco was introduced from Mexico in the sixteenth century. These were known in the East generations earlier."

And so, with the mere melody of his voice, he re-established his sovereignty over Sheard's mind. His extraordinary knowledge of extraordinary matters occasioned the pressman's constant amazement. From the preparations made for the reception of the Queen of Sheba at Solomon's court in 980 B.C. he passed to the internal organisation of the Criminal Investigation Department.

"I should mention," said Sheard at this point, "that an attempt was made to follow me here."

Séverac Bablon waved a long white hand carelessly.

"Never mind," he replied soothingly. "It is annoying for you, but I give you my word that you shall not be compromised by me—come, luncheon is waiting. I will show you the only three men in Europe and America who might associate the bandit, the incendiary, with him who calls himself Séverac Bablon."
