He moved to her side and grasped her left wrist. "For God's sake, get away from here!" he whispered. "I shouldn't have let you come. I warned you it wasn't safe. Someone followed me. Get out quickly!"
Almost without meaning to she lowered her voice, trying to keep it steady. "You're trying to put me off. I'm not having any. We're here to talk business."
He spoke with a kind of suppressed venom. "You know what happened to your brother. Do you want to go the same road? I tell you I'm being watched. Come away from here quickly!"
He pulled her towards the door. Realising that his agitation was not feigned she went with him and allowed him to hurry her back into the shelter of the trees. He stopped to listen again. She could hear nothing, but he drew her still farther into the shade.
He let her go. "I daren't stop. I swear I'm on the level. I'll meet you, but not here. It's getting too hot for me. You ought never to have rung me up." He broke off to listen again. "He's on to me," he whispered. "I'll have to go. For God's sake, miss, go back to London! You're in much worse danger than you know. I'll meet you - on my word, I will!"
"You'd better," she said. "You know what I'm holding."
He gave a soundless chuckle. "Half a loaf, miss. That's not enough."
"Enough to make things unpleasant for you," she said harshly.
"Do that and you'll never get your other half," he said. His tone held a menace. "You were mad to come here. You're not safe. I can't be on the watch all the time. You're not safe a moment."
She said steadily: "I shall stay at Upper Nettlefold till I get what I came for."
His hand closed on her wrist again compellingly. With his lips almost touching her ear he breathed the one word: "Listen!"
The wood seemed all at once, to her overwrought nerves, to be alive with tiny, nameless sounds. The fallen leaves rustled, perhaps a rabbit stirred amongst them; a twig cracked; the shadow of a tree seemed to move.
The man's fear communicated itself to Shirley. She felt that hidden eyes watched her and suddenly wanted only to get away from this haunted spot. Her hand shook in the valet's hold. He let it go and gave her a little push. "Go! You mustn't be seen with me. For God's sake, go!"
He moved away softly as a ghost. The night seemed to close in on Shirley, full of unknown perils. For a moment she knew a feeling of sheer panic that held her as though by force where she stood, her knees shaking. She threw it off and managed to take a step forward on to the ride. It had grown so dark that nothing was clearly distinguishable any longer. Not daring to switch on her torch she began to walk quickly away from the pavilion, restraining an impulse to break into a run.
She was brought up short by a circle of light that suddenly appeared a little way to the left of the ride, moving uncannily over the ground. There was someone else in the wood, searching.
She turned and made for the cover of the trees, hardly caring what direction she took. A great beech tripped her with its long roots; she fell, and looking back, saw the light moving towards her. She scrambled up, thankful in the midst of her fright that the safety-catch on her Colt was up. She broke into a run, heading for the thickest part of the wood.
Brambles caught at her coat and slashed her ankles; she tore free and reached a clump of blackberry bushes growing between the slender stems of some silver birch trees. She crouched down behind them, watching the light waver through the undergrowth.
She could hear footsteps now, deliberate steps, coming closer. A slight sound behind her brought her head round with a jerk, but she could see nothing.
The footsteps passed the bush; she could just perceive the darker shadow of a man's form. He stopped and stood still, listening, she guessed. The light he carried began to describe a circle; she wondered how dense the bushes were, whether dense enough to conceal her.
The man moved; he was coming round the bush. Her thumb felt for the safety-catch; she stayed still, waiting.
Then the boding silence was broken by a sound so incongruous that it came as a shock to her. Someone not far away was whistling "The Blue Danube."
The light disappeared; a faint rustle, the brush of a body passing through high bracken came to Shirley's cars, followed by complete silence. The whistle died away, the shadow had gone.
It was minutes before she dared to move. She crept forward in the direction where she judged the ride to be, stopping every few paces to stand still and listen. The light was no longer visible; it had vanished altogether, scared away by the sound of a waltz tune whistled in the distance.
She walked on, thrusting her way through the undergrowth, still not daring to use the torch.
No light warned her that she was still being followed. Several times she thought that she could hear the sound of a panting breath not far behind; once a twig cracked ominously, but when she stood still, peering behind her, she could see nothing and hear nothing.
She moved forward again; again she heard the heavy breathing, closer at hand now.
She fled on and stumbled out onto the ride. With the close turf under her feet and the dim outlines of the trees on either side to guide her she broke into a run.
A light flashed full into her face; a tiny scream, instantly checked, broke from her. She stood still and levelled the gun.
A cool, faintly mocking voice spoke: "Whither away, Miss Brown?" it said.
Her pistol-hand fell to her side; she drew a long, sobbing breath. "You!" she gasped, dizzy with relief. "It's only - you!"
"That," said Mr. Amberley strolling towards her, "is not particularly complimentary. You seem to be in a hurry."
She put her hand out, clasping the sleeve of his coat; there was something comforting about its very roughness. "Someone following me," she said. "Someone following me."
He took her hand in a strong clasp; she was aware, through her jumbled emotions, that she was no longer afraid. She held Mr. Amberley's hand gratefully and followed the beam of his torch as it swung round.
Then a sharp exclamation rose to her lips. The torch had lit up a face for one moment, a face that shone pale in the bright light and disappeared instantly behind a bush.
"Who is that man?" she gasped. "Over there - didn't you see? He was watching us. Oh, let's get away!"
"By all means," agreed Amberley. "It's not really much of a night for a country walk."
"Did you see?" she insisted. "A man by that bush. Who was he? He was following me. I heard him."
"Yes, I saw," replied Amberley. "It was Fountain's new butler."
She drew closer to him instinctively. "I didn't know. He was following me. I - I don't quite - please let us go!"
Mr. Amberley drew her hand through his arm and began to walk with her down the ride towards the gate. Once she glanced back, saying nervously: "You're sure he's not still following?"
"No, I'm not sure, but I'm not letting it worry me," said Amberley. "Probably he is seeing us off the premises. This happens to be private property, you know."
"You don't think that!" she said sharply. "He wasn't following for that reason."
"No?" said Amberley. "Well, suppose you tell me what the reason is?"
She was silent. After a few moments she pulled her hand away and said: "What are you doing here?"
"Getting back to your normal self, aren't you?" remarked Mr. Amberley. "I thought it was too good to last. What I should like to know is, what are you doing here?"
"I can't tell you," she said curtly.
"Won't tell me," he corrected.
"Perhaps. I notice you haven't answered me."
"Oh, there's no mystery about me," said Amberley cheerfully. "I was following you."
She stopped dead in her tracks. "You? You followed me? But how? How did you know where I was going."
"Intuition," grinned Mr. Amberley. "Aren't I clever?"
"You can't have known. Where were you?"
