They were suddenly surprised by observing a horseman come galloping down the road. He drew rein opposite the compound, and, springing from his saddle, hurried to the verandah. It was Lieutenant Harper.

“Walter, a word with you,” he cried. “Do not be alarmed, Flo,” he added, quickly, as he observed her cheeks blanch.

She sprang to her feet quickly, and grasped his arm.

“Tell me,” she cried, “what is the matter. I see by your manner that there is danger. Where does it threaten?”

“Do not be alarmed,” he repeated; “there is danger, but we may avert it. I must not stay, though. I am bound on secret service to Delhi, and I must reach that city before the day breaks. I am guilty of a great dereliction of duty in calling here; but I could not leave without seeing you. Walter, order your horse to be saddled, and accompany me as far as the Delhi road. I want to talk to you.”

“But Flora—how can I leave her?” Walter asked, in agitation.

“Never mind me,” she answered. “Go; it may be to our benefit.”

“Yes; it will be. I have some plans to arrange,” said Harper.

In a few minutes Walter’s horse stood in the compound.

“You have a case of revolvers?” Walter said to Flora.
