“We must stop here,” whispered the guide, as she drew Harper and Martin into the shadow of a buttress. “A few yards farther on is a gate, but we can only hope to get through it by stratagem. I am unknown to the guard. This dress will not betray me. I will tell them that I live on the other side of the river, and that I have been detained in the city. I will beg of them to let me out. You must creep up in the shadow of this wall, ready to rush out in case I succeed. The signal for you to do so shall be a whistle.” She displayed a small silver whistle as she spoke, which hung around her neck by a gold chain. She walked out boldly now, and was followed by the two men, who, however, crept along stealthily in the shadow of the wall. They stopped as they saw that she had reached the gate. They heard the challenge given, and answered by Haidee. In a few minutes a flash of lightning revealed the presence of two Sepoys only. Haidee was parleying with them. At first they did not seem inclined to let her go. They bandied coarse jokes with her, and one of them tried to kiss her. There was an inner and an outer gate. In the former was a door that was already opened. Through this the two soldiers and Haidee passed, and were lost sight of by the watchers, who waited in anxious suspense. Then they commenced to creep nearer to the gateway, until they stood in the very shadow of the arch; but they could hear nothing but the wind and rain, and the occasional thunder. The moments hung heavily now. Could Haidee have failed? they asked themselves. Scarcely so, for she would have re-appeared by this time. As the two men stood close together, each might have heard the beating of the other’s heart. It was a terrible moment. They knew that their lives hung upon a thread, and that if this devoted woman failed, nothing could save them. Still they did not lose hope, though the suspense was almost unendurable. Each grasped his pistol firmly, to be used as a club if occasion required. The termination of what had verily seemed an hour to them, but in reality only five minutes, brought the welcome signal--the whistle was blown. “You first, Harper,” said Martin. They darted from their hiding-place and rushed through the door; a Sepoy tried to bar the passage, but was felled by a blow from Harper’s pistol; in another moment they were outside the walls--Haidee was waiting for them. “Speed!” she cried, leading the way. The alarm was already being spread. A deep-toned gong, that could be heard even above the howling wind, was warning the sentries that something had happened.
