"Not what you have done, my General--what the English army has done. An old score, General--thirty years old. My father--he was a prince in India--until this English army took away his throne to give it to a lying brother. The army--the English army--murdered my father when he tried to get it back--called it mutiny. Ah, yes, an old score; but by the breath of Allah, to-night shall see it paid!" The man's eyes were glittering points of white-hot steel. All of his thin white teeth showed like a hound's. "You dog!" The general feebly wagged his head at the Indian. "Your dog, my General. Five years your dog, when I might have been a prince. My friend goes up the Rock--step--step--step. Closer--closer to the tower, my General. And Major Bishop--where is he? Ah, a knife is swift and makes no noise----" "What a fool I've been!" Crandall rocked in his chair, and passed a trembling hand before his eyes. Sudden rage turned his bloodshot eyes to where the girl was stretched, sobbing, across the desk. "Your man--the man you protected--it is he who goes to the signal tower, girl!" "No--no; it can't be," she whispered between the rackings of her throat. "It is! Only a member of the signal service could gain admittance into the tower to-night. Besides--who was it went with Bishop down the Rock after the dinner to-night? And I--I sent Bishop with him--sent him to his death. He was tricking you all the time. I told you he was. I warned you he was playing with you--using you for his own rotten ends--using you to help kill forty thousand men!" It needed not the sledge-hammer blows of the stricken Crandall to batter Jane Gerson's heart. She had read too clearly the full story Jaimihr Khan's sketchy comments had outlined. She knew now Captain Woodhouse, spy. The Indian was talking again, his words dropping as molten metal upon their raw souls. "Forty thousand men! A pleasant thought, my General. Eight minutes up the Rock to the tower when one moves fast. And my friend--ah, he moves veree--veree fast. Eight minutes, and four have already passed. Watch the windows--the windows looking out to the bay, General and Sahibah. They will flame--like blood. Your hearts will stop at the great noise, and then----" A knock sounded at the double doors behind Jaimihr. He stopped short, startled. All listened. Again came the knock. Without turning his eyes from the two he guarded, Jaimihr asked: "Who is it?" "Woodhouse," came the answer. Jane's heart stopped. Crandall sat frozen in his seat. Jaimihr turned the key in the lock, and the doors opened. In stepped Captain Woodhouse, helmeted, armed with sword and revolver at waist. He stood facing the trio, his swift eye taking in the situation at once. Crandall half rose from his seat, his face apoplectic. "Spy! Secret killer of men!" he gasped. Woodhouse paid no heed to him, but turned to Jaimihr.
