“But you do not know all. You remember finding the seal in your cell?”
“Ah—the seal?” I cried, excitedly, for the mention of it brought back terrible memories. “What was its meaning?” I demanded.
“By the merest accident you directed my attention to the hieroglyphics on the wall, and the discovery threw a light upon a phase of the mystery that had hitherto been unintelligible. That cell, I found, was the same in which my father was confined before his exile, and it was he who cut that emblem in the stone, with his initials linked with those of the villain who plotted his destruction.”
“And that villain was—”
“The man you know as Hertzen. Having obtained control of my sister’s fortune, he schemed to entangle her so that he might be instrumental in securing her exile to the mines, and eventually appropriate the money for his own use. He was unaware, however, that my wound in Georgia had not proved fatal. By concealing my identity I contrived to assist Vera and yourself.”
“But the seal! Tell me; what is its meaning?” I asked, in breathless suspense.
“It is the death symbol. The Nihilist law demands that those who accidentally discover our secret, and refuse to take the oath, must die by the hand of the person from whose lips they learn it. To ensure absolute secrecy, so essential in a country like Russia teeming with police spies, the Executive devised a seal to be affixed to the body of the murdered person, thus showing members of our Cause the reason of the crime and deterring them from betraying us.”
“So the seal, about which there has been so much controversy, is a Nihilist emblem,” I said, bewildered.
“Purely. For the most part the persons upon whose bodies the seal has been discovered are those whom it was found necessary to remove for the preservation of our secret. In some cases where we have been betrayed by members of our Circle, lots have been cast among us, the deed has been committed, and the lips of the traitor silenced forever. The crimes have been regarded as the work of a maniac. You will understand that it was to our interest to make them appear so,” he replied, calmly.
“What is the meaning of those strange symbols around the seal which have been the cause of so much comment?” I asked, eagerly, for this extraordinary revelation was even more mystifying than the secrets.
