"You have got to know," he said, his face purple with pa.s.sion, and he flung out his arm as though he would dash his fist into her face. But as he stood with his arm poised there came a singular change upon his face.

"Did you hear anything?" he asked in a whisper.

All listened, and all heard in the quiet of the night a faint click, and after an interval they heard it again, and after another but shorter interval yet once more.

"That's the gate," said Wethermill in a whisper of fear, and a pulse of hope stirred within Celia.

He seized her wrists, crushed them together behind her, and swiftly fastened them once more. Adele Rossignol sat down upon the floor, took the girl's feet upon her lap, and quietly wrenched off her shoes.

"The light," cried Wethermill in an agonised voice, and Helena Vauquier flew across the room and turned it off.

All three stood holding their breath, straining their ears in the dark room. On the hard gravel of the drive outside footsteps became faintly audible, and grew louder and came near. Adele whispered to Vauquier:

"Has the girl a lover?"

And Helene Vauquier, even at that moment, laughed quietly.

All Celia's heart and youth rose in revolt against her extremity. If she could only free her lips! The footsteps came round the corner of the house, they sounded on the drive outside the very window of this room. One cry, and she would be saved. She tossed back her head and tried to force the handkerchief out from between her teeth. But Wethermill's hand covered her mouth and held it closed. The footsteps stopped, a light shone for a moment outside. The very handle of the door was tried. Within a few yards help was there--help and life. Just a frail latticed wooden door stood between her and them. She tried to rise to her feet. Adele Rossignol held her legs firmly. She was powerless. She sat with one desperate hope that, whoever it was who was in the garden, he would break in. Were it even another murderer, he might have more pity than the callous brutes who held her now; he could have no less. But the footsteps moved away. It was the withdrawal of all hope. Celia heard Wethermill behind her draw a long breath of relief. That seemed to Celia almost the cruellest part of the whole tragedy. They waited in the darkness until the faint click of the gate was heard once more. Then the light was turned up again.

"We must go," said Wethermill. All the three of them were shaken. They stood looking at one another, white and trembling. They spoke in whispers. To get out of the room, to have done with the business--that had suddenly become their chief necessity.

Adele picked up the necklace and the rings from the satin-wood table and put them into a pocket-bag which was slung at her waist.

"Hippolyte shall turn these things into money," she said. "He shall set about it to-morrow. We shall have to keep the girl now--until she tells us where the rest is hidden."

"Yes, keep her," said Helene. "We will come over to Geneva in a few days, as soon as we can. We will persuade her to tell." She glanced darkly at the girl. Celia shivered.

"Yes, that's it," said Wethermill. "But don't harm her. She will tell of her own will. You will see. The delay won't hurt now. We can't come back and search for a little while."

He was speaking in a quick, agitated voice. And Adele agreed. The desire to be gone had killed even their fury at the loss of their prize. Some time they would come back, but they would not search now--they were too unnerved.

"Helene," said Wethermill, "get to bed. I'll come up with the chloroform and put you to sleep."

Helene Vauquier hurried upstairs. It was part of her plan that she should be left alone in the villa chloroformed. Thus only could suspicion be averted from herself. She did not shrink from the completion of the plan now. She went, the strange woman, without a tremor to her ordeal. Wethermill took the length of rope which had fixed Celia to the pillar.

"I'll follow," he said, and as he turned he stumbled over the body of Mme. Dauvray. With a shrill cry he kicked it out of his way and crept up the stairs. Adele Rossignol quickly set the room in order. She removed the stool from its position in the recess, and carried it to its place in the hall. She put Celia's shoes upon her feet, loosening the cord from her ankles. Then she looked about the floor and picked up here and there a sc.r.a.p of cord. In the silence the clock upon the mantelshelf chimed the quarter past eleven. She screwed the stopper on the flask of vitriol very carefully, and put the flask away in her pocket. She went into the kitchen and fetched the key of the garage.

She put her hat on her head. She even picked up and drew on her gloves, afraid lest she should leave them behind; and then Wethermill came down again. Adele looked at him inquiringly.

"It is all done," he said, with a nod of the head. "I will bring the car down to the door. Then I'll drive you to Geneva and come back with the car here."

He cautiously opened the latticed door of the window, listened for a moment, and ran silently down the drive. Adele closed the door again, but she did not bolt it. She came back into the room; she looked at Celia, as she lay back upon the settee, with a long glance of indecision. And then, to Celia's surprise--for she had given up all hope--the indecision in her eyes became pity. She suddenly ran across the room and knelt down before Celia. With quick and feverish hands she untied the cord which fastened the train of her skirt about her knees.

At first Celia shrank away, fearing some new cruelty. But Adele's voice came to her ears, speaking--and speaking with remorse.

"I can't endure it!" she whispered. "You are so young--too young to be killed."

The tears were rolling down Celia's cheeks. Her face was pitiful and beseeching.

"Don't look at me like that, for G.o.d's sake, child!" Adele went on, and she chafed the girl's ankles for a moment.

"Can you stand?" she asked.

Celia nodded her head gratefully. After all, then, she was not to die.

It seemed to her hardly possible. But before she could rise a subdued whirr of machinery penetrated into the room, and the motor-car came slowly to the front of the villa.

"Keep still!" said Adele hurriedly, and she placed herself in front of Celia.

Wethermill opened the wooden door, while Celia's heart raced in her bosom.

"I will go down and open the gate," he whispered. "Are you ready?"

"Yes."

Wethermill disappeared; and this time he left the door open. Adele helped Celia to her feet. For a moment she tottered; then she stood firm.

"Now run!" whispered Adele. "Run, child, for your life!"

Celia did not stop to think whither she should run, or how she should escape from Wethermill's search. She could not ask that her lips and her hands might be freed. She had but a few seconds. She had one thought--to hide herself in the darkness of the garden. Celia fled across the room, sprang wildly over the sill, ran, tripped over her skirt, steadied herself, and was swung off the ground by the arms of Harry Wethermill.

"There we are," he said, with his shrill, wavering laugh. "I opened the gate before." And suddenly Celia hung inert in his arms.

The light went out in the salon. Adele Rossignol, carrying Celia's cloak, stepped out at the side of the window.

"She has fainted," said Wethermill. "Wipe the mould off her shoes and off yours too--carefully. I don't want them to think this car has been out of the garage at all."

Adele stooped and obeyed. Wethermill opened the door of the car and flung Celia into a seat. Adele followed and took her seat opposite the girl. Wethermill stepped carefully again on to the gra.s.s, and with the toe of his shoe sc.r.a.ped up and ploughed the impressions which he and Adele Rossignol had made on the ground, leaving those which Celia had made. He came back to the window.

"She has left her footmarks clear enough," he whispered. "There will be no doubt in the morning that she went of her own free will."

Then he took the chauffeur's seat, and the car glided silently down the drive and out by the gate. As soon as it was on the road it stopped. In an instant Adele Rossignol's head was out of the window.

"What is it?" she exclaimed in fear.

Wethermill pointed to the roof. He had left the light burning in Helene Vauquier's room.

"We can't go back now," said Adele in a frantic whisper. "No; it is over. I daren't go back." And Wethermill jammed down the lever. The car sprang forward, and humming steadily over the white road devoured the miles. But they had made their one mistake.

CHAPTER XX

THE GENEVA ROAD

The car had nearly reached Annecy before Celia woke to consciousness.

And even then she was dazed. She was only aware that she was in the motor-car and travelling at a great speed. She lay back, drinking in the fresh air. Then she moved, and with the movement came to her recollection and the sense of pain. Her arms and wrists were still bound behind her, and the cords hurt her like hot wires. Her mouth, however, and her feet were free. She started forward, and Adele Rossignol spoke sternly from the seat opposite.

"Keep still. I am holding the flask in my hand. If you scream, if you make a movement to escape, I shall fling the vitriol in your face," she said.
