The night was cloudy. Only at infrequent intervals the moon soared turbulently out from the somber cloud-hills and glinted brightly through the live oaks overhead. Carl had been drinking heavily since the morning, with vicious recourse to the flute when his mood was darkest. Now he felt strung to a curious electric tension, with pulse and head throbbing powerfully like a racing engine. Still there was satanic keenness in his mind to-night, a capacity for concentration that surprised him. Somewhere in his head, taut like an overstrung ligament or the string of a great violin, something sinister droned and hummed and subtly threatened. For the hundredth time he made a systematic list of recurrent symbols, noting again the puzzling similarity of the twisted signs, but no sign appeared frequently enough to do vowel work. To-night somehow the cipher mocked and gibed and goaded him to frenzy. The mad angles pointing up and down and right and left--it was impossible to sort them. They danced and blurred and crept irresistibly into the wrong list. And in error came solution. Carl glanced intently at the jumbled list and fell feverishly to working from a different viewpoint. From the cryptic snarl came presently the single English word in the cipher--his name. The keen suspicion of his hot brain had, at last, been right. For every letter in the alphabet, four symbols had been used interchangeably but whether they pointed up or down or right or left, their significance was the same. There were no word divisions. When at last Ronador's frantic message to the Baron lay before him, Carl was grateful for the quiet monastery days in Houdania with Father Joda. They had given him an inkling of the language. Some of the message, to be sure, was missing--for Themar had been interrupted--and some of it unintelligible. But clear and cold before his fevered eyes lay the words which marked him irrevocably for the knife of a hired assassin. There was no suggestion of sealing his lips with gold, as in a drunken moment he had suggested in his letter. The seal of death was safer than the seal of gold. Seeing the sinister command there before him, even though the knowledge was not new, Carl felt a nameless fury rise in his reeling brain. He must live--live--live! he told himself fiercely. With the vivid, lovely face of Keela tormenting him to sensual conquest, he must live no matter what the price! How safeguard his life from the men who were hunting him? What if Diane were to--_die_? Carl shuddered. Then the sirocco of fear and hate centering about her, would blow itself out forever and his own life would be safe, for the secret would be worthless. These men--Tregar, Ronador, Themar--scrupled for vastly different reasons to take the life of a woman.
