Idris smiled.

"Perhaps I have done wrong in letting people think that I perished in the burning of the 'Hôtel de l'Univers.' At the time of the fire I was at the opera-house. On leaving I found the boulevards ringing with the news. I bought a newspaper and discovered my own name erroneously inserted among the list of victims. I resolved not to set the mistake right, for it suddenly occurred to me that here was a convenient opportunity to die—to the world. Wherever I went, the name Marville recalled my father's crime, or rather, supposed crime. 'Let the world think that Eric Marville's son is dead,' I thought, 'and let him begin life anew, and under a different name.'"

"Was the yacht Nemesis, in which your father escaped, never heard of again?" asked Godfrey.

"It vanished, leaving not a trace behind."

"Strange! The news of your father's escape, together with a description of the delinquent vessel, would be telegraphed to all civilized countries. Every ocean-steamer, every seaport, would be on the watch for the yacht, and yet you say it was never seen again."

"Its disappearance shows how well Captain Rochefort had devised his plans," Idris answered.

"Since your father did not communicate with you, his only son, it follows, almost as a matter of course, that he did not communicate with his more distant relatives?"

"His relatives, if he had any, are unknown to me: in fact, I am quite in the dark as to my father's antecedents. Among all his papers there was not one letter relating to his kinsfolk, nor any clue whatever to indicate his history prior to his settling at Nantes in 1866."

"You are certain that your father was English born? Because if so, his name, and date and place of birth, together with his parents' names, should be among the records of Somerset House."
