Slowly she moved along the wall. If only she could reach a door! If she only could!

But that door was a distance of some fifty yards away. Could she make it?

Stealthily she moved forward. Stopping now and then to listen, she caught as before the stealthy pit-pat of footsteps. Once some object rattled on the floor and she heard a muffled exclamation. Then she caught a creaking sound—was he mounting the stair? Had the banister creaked?

Now she was twenty yards from the door, now ten, now five, and now—now she gripped its casing. Excitedly she swung around, only to find herself facing a rusted square of steel. The labyrinth of rooms was closed to her. She was trapped on a narrow balcony with no way to turn for escape.

As she crouched there trembling, her hand touched something cold—her skate. Here was hope; if the worst came to worst, here was a formidable weapon and she was possessed of the power to swing it.

Cautiously she drew it from her belt, then crouching low, gripping the small end, she waited.

Came again the pit-pat-pit-pat. He was on the balcony, she felt sure of that now. Her hand gripped the skate until the blade cut through the skin, but still she crouched there waiting.

“I think we should go out and look for her,” said Lucile.
