A footstep was dying away within, so she knocked and called, and after a moment an old soldier, a kind of caretaker of the Citadel, opened the gate to her.

"Beg pardon, Miss! Lieutenant Robson told me to shut up everything immediately," he said, but Helena did not wait for further explanation.

There was nobody in sight when she passed the kitchen quarters, and when she entered the house a chill silence seemed to strike to the very centre of her life.

Then followed one of those mystic impulses of the human heart which nobody can understand. In her creeping fear of what might have happened during her absence she was at first afraid to go into her father's room. If she had done so, there and then, and without an instant's hesitation, she must have found Gordon kneeling over her father's body. But in dread of learning the truth she tried to keep back the moment of certainty, and in a blind agony of doubt she stood and tried to think.

The voices of the men were no longer to be heard through the wall, and the deep rumble of the crowd outside had died away, therefore the Egyptian must have gone. Had her father gone too? She remembered that he was in uniform, and took a step back into the hall to see if his cap hung on the hat-rail. The cap was there. Had he gone into his bedroom? She crossed to the door. The door was open and the room was empty.

Hardly able to analyse her unlinked ideas, but with a gathering dread of the unknown, she found herself stepping on tiptoe towards the General's office. Then she thought she heard a faint cry within, a feeble, interrupted moan, and in an unsteady voice she called.

There was no answer. She called again, and still there was no reply. Then girding up her heart to conquer a vague fear, which hardly knew itself yet for what it was, she opened the door.

The room was almost dark. She took one step into the gloom, breathing rapidly, then stopped and said—

"Father! Are you here, father?"

There was no sound, so she took another step into the room, thinking to switch on the light over the desk and at the same time to reach the sofa. As she did so she stumbled against something, and her breath was struck out of her in an instant.
