"Wait a bit, my son," said Arthur. "I have thought about that incident rather carefully. Remember that Morse was given a certain time in which to come in line and join the Hermandad. From what I have heard of the punctilious, senile Marquis da Silva, he wouldn't have allowed the campaign against Morse to be started a moment before the time of immunity was up. Might not Midwinter at that time, quite ignorant that the towers were being built as a refuge for Morse, have tried to go behind his own employers and offer to betray them, and to drop the whole business for a million or so? From what I know of the man's career I should think it extremely probable."
I whistled. Arthur seemed to have penetrated to the center of that night's mystery. There was nothing more likely. I could imagine the whole scene, the panther man laying his cards on the table and offering to save Morse and Juanita from certain death--Morse, already half maddened by what hung over him, chuckling in the knowledge that he had built an impregnable refuge, dismissing the scoundrel with utter firmness and contempt.
"I believe you've hit it, Arthur," I said. "It fits in like the last bit of a jig-saw puzzle."
"I'm pretty sure myself, but even now you don't know all. Quite early in his life, when Midwinter--he's the last of the Staffordshire Midwinters, an ancient and famous family--was expelled from Harrow, he went out to South America. Morse was at that time in the wilds of Goyaz, where he was developing his mines. There was a futile attempt to kidnap the child, Juanita, who was then about two years old, and Midwinter was in it. The young gentleman, I understand, was caught. Morse was then, as doubtless he is now, a man of a grim and terrible humor. He took young Midwinter and treated him with every possible contemptuous indignity. They say his head was shaved; he was birched like a schoolboy by Morse's peons; he was branded, tarred and feathered, and turned contemptuously adrift. The fellow came back to Europe, married a celebrated actress in Paris, who is now dead, and has been, as I say, one of the most successful uncaught members of the higher criminal circles that ever was. He made an attempt at the Ritz, swallowing his hatred. It failed. His employers in Brazil know nothing of it. He is here in London--as Pat so wonderfully discovered--supplied with unlimited money, burning with a hatred of which a decent man can have no conception, and confronted with his last chance in the world."
