Fear lent her caution. She skirted the edge of the wide lawn in the shadow of the trees, running like a deer across the moonlit spaces, always keeping the masses of evergreens between her and the wicket gate until she reached the flower garden, where she paused a moment to get her breath. A patch of moonlight lay between her and the entrance and the hedge was impenetrable. There was no other way. She bent low and hurried forward, trusting to the good fortune that had so far aided her. Halfway across the open she heard a shout and knew that she had been seen. There was nothing for it but to run straight for the house. So catching her skirts up above her knees and scorning the garden path which would have taken her a longer way, she made straight for the terrace, the main door of which she knew had been left open for her return. Across the wide lawn in the bright moonlight she ran, her heart throbbing madly, the precious yellow packet clutched tightly against her palm. Out of the tail of her eye she saw dark forms emerge from the bushes and run diagonally for the terrace steps in the hope of intercepting her. But she was fast, and she blessed her tennis for the wind and muscle to stand the strain. She was much nearer her goal than her pursuers, but they came rapidly, their bulk looming larger every moment. She saw the lights and knew that servants were at hand. Her father, too, was in the library, for she saw the glow of his reading-lamp. She had only to shout for help now and someone would hear her. She tried to, but not a sound came from her parching throat. With a last effort she raced up the terrace steps, pushed open the heavy door and shut and bolted it quickly behind her. Then sank into the nearest piece of furniture in a state of physical collapse. Doris Mather did not faint, an act which might readily have been forgiven her under the circumstances. Her nerves were shaken by the violence of her exercise and the narrowness of her escape, and it was some moments before she could reply to the anxious questions that were put to her. Then she answered evasively, peering through the windows at the moonlit lawn and seeing no sign of her pursuers. In a few moments she drank a glass of water and took the arm of Wilson, her maid, up the stairway to her rooms, after giving orders to the servants that her father was not to be told anything except that she had come in very tired and had gone directly to bed.
