"Now come, I know of course who you are, I know everybody in Valoro, and especially the members of the Carlotta Society, which is avowedly Royalist and opposed to the present Government like myself. You are a member of that Society; you are one of its leaders. I suggest to you that the so-called band of robbers who attacked the train last night were simply members of the Carlotta Society?"

"I admit," gasped the man, trying with all his force to keep the boa-constrictor's head away from his face, "that I am a leader of the Carlotta Society, but I cannot disclose its secrets even to you."

"You must speak, Lopes," Don Juan said, "or you will not get free. Remember that I am a member of the Carlotta Society myself, though an honorary one on account of my age. You will never get back to your desk in the bank of Valoro if you don't speak."

"It is inhuman!" cried the man desperately, "it is vile torture!"

"It is also inhuman," added Don Juan sententiously, "to raid trains, and to threaten murder as you have done in this room. Your band too was none too scrupulous in hanging Jimenez the half-breed, though he was an informer. Tell me now, why did you hold up the train? why did you try to rob this English gentleman?"

"It was done," answered the man stertorously, for he was becoming weak, "it was done on urgent orders from Europe from our head."

Don Juan started, and going close whispered a name in his ear.

"Yes," replied Lopes faintly, but I heard the words, "from the Duke himself."

As Don Juan turned from him with a perplexed look, his eye caught the casket which I still held in my hand; he lost colour and became very agitated as he saw it.

"Where did you get that from?" he asked abruptly, seizing my hand.
