"The voice, again," Dr. Beddersley continued. "The voice itself may be most fallacious. The man is no doubt a clever mimic. He could, perhaps, compress or enlarge his larynx. And I judge from what you tell me that he took characters each time which compelled him largely to alter and modify his tone and accent."

"Yes," I said. "As the Mexican Seer, he had of course a Spanish intonation. As the little curate, he was a cultivated North-countryman. As David Granton, he spoke gentlemanly Scotch. As Von Lebenstein, naturally, he was a South-German, trying to express himself in French. As Professor Schleiermacher, he was a North-German speaking broken English. As Elihu Quackenboss, he had a fine and pronounced Kentucky flavour. And as the poet, he drawled after the fashion of the clubs, with lingering remnants of a Devonshire ancestry."

"Quite so," Dr. Beddersley answered. "That is just what I should expect. Now, the question is, do you know him to be one man, or is he really a gang? Is he a name for a syndicate? Have you any photographs of Colonel Clay himself in any of his disguises?"

"Not one," Charles answered. "He produced some himself, when he was Medhurst the detective. But he pocketed them at once; and we never recovered them."

"Could you get any?" the doctor asked. "Did you note the name and address of the photographer?"

"Unfortunately, no," Charles replied. "But the police at Nice showed us two. Perhaps we might borrow them."

"Until we get them," Dr. Beddersley said, "I don't know that we can do anything. But if you can once give me two distinct photographs of the real man, no matter how much disguised, I could tell you whether they were taken from one person; and, if so, I think I could point out certain details in common which might aid us to go upon."

All this was at lunch. Amelia's niece, Dolly Lingfield, was there, as it happened; and I chanced to note a most guilty look stealing over her face all the while we were talking. Suspicious as I had learned to become by this time, however, I did not suspect Dolly of being in league with Colonel Clay; but, I confess, I wondered what her blush could indicate. After lunch, to my surprise, Dolly called me away from the rest into the library. "Uncle Seymour," she said to me—the dear child calls me Uncle Seymour, though of course I am not in any way related to her—"I have some photographs of Colonel Clay, if you want them."

"You?" I cried, astonished. "Why, Dolly, how did you get them?"

For a minute or two she showed some little hesitation in telling me. At last she whispered, "You won't be angry if I confess?" (Dolly is just nineteen, and remarkably pretty.)
