The reporter continued, still in the same frigid tone:
“I am sure of it—and there is no reason why the idea should surprise you, Madame, since it has not for a moment left your own mind. As to the rest of us, is it not true, gentlemen, that the idea has occurred to each one of us at the same moment on the day when we took luncheon on the terrace of the Bold when all our eyes were hidden by the black glasses? If I except Mrs. Rance, who is there among us that did not feel the presence of Larsan at that time?”
“That is a question which ought to be propounded to Professor Stangerson as well as to the rest of us,” interposed Arthur Rance, instantly. “For from the moment when we begin any course of reasoning along these lines, I can see no object in not having the Professor, who was at the table at luncheon with us on that day, here at this time also.”
“Mr. Rance!” cried the Lady in Black.
“Yes, I must repeat it, if you will pardon me,” replied Edith’s husband, haughtily. “Monsieur Rouletabille was wrong to generalize when he said, ‘All the members of the house party——’”
“Professor Stangerson is so far from us in spirit that I have no need of his presence here,” pronounced Rouletabille in a tone so stern and solemn that it fell impressively on the ears of each and every one among us. “Although Professor Stangerson had lived with us in the Château of Hercules, he was not one of us in regard to feeling the presence of Larsan on that day. And Larsan is here among us.”
This time we stole stealthy glances at each other as though we suspected each other of stealing, and the idea that Larsan might really be among us appeared to me so mad that I exclaimed, forgetting that I had promised not to address Rouletabille:
“But at that luncheon on the terrace, there was still another person whom I do not see here.”
Rouletabille cast an angry look at me as he answered:
“Still Prince Galitch! I have already told you, Sainclair, with what task the Prince is occupying himself on this frontier and I swear to you that it is not the trouble of Professor Stangerson’s daughter which concerns him. Leave Prince Galitch to his humanitarian labors!”
