"It is on her account, Cethegus, that I come," said Anicius gravely. "You are the oldest friend of my father and of our house. You hid Severinus and me from our enemies, and assisted us to escape at your own risk. You are the only man in Byzantium to whom I can appeal in a mysterious affair. A few days ago I received this incomprehensible letter, 'To the son of my patron; Corbulo the freedman----"

"Corbulo? I know that name!"

"The letter ends here," said Cethegus.

"Yes. Corbulo lost his senses and never again became conscious, the mercenary said."
