It did not occur to Juliet to deny that she had overheard their talk. She had been found in the act of spying on them, and it was inconceivable that they should believe she had not done so. Besides, she was raging at the thought of what she had heard, and her anger gave her a courage she might otherwise have found it hard to maintain.
"I have been there all the time," she declared stoutly. "I heard all you said, you wicked, wicked man. A murderer! Oh, how horrible it all is!"
Julia laid a hand on Mark's arm.
"She will tell what she knows," she said, trembling.
"She shall not," Mark stammered furiously. He seemed to be half suffocating with rage. "She shall not go unless she swears to say nothing. Swear it, I say!"
He seized Juliet by the shoulder and shook her violently to emphasize his words.
"I won't swear anything of the kind," she retorted, trying to break from his grasp. "Do you suppose you can kill me, too, without being found out? There is a detective here now, and Sir David Southern is not at hand to lay the blame on. You coward! How dare you touch me!"
The truth of her words seemed to strike home to Mark, for he left go of her suddenly, and stood, biting his nails and scowling, the picture of irresolution and malignance.
Juliet lost no time in following up any advantage she might have gained.
"I can't help knowing that you care for him," she said, addressing herself to Julia, "though I wouldn't have listened to that part if I could have helped it. But how can you? How can you? I can't understand how you can feel as you do about killing people, but at least if you did such a thing you would imagine it was for the good of your country, while this man thinks of nothing but his own selfish ends. Money, that is all he wants! How can you condone such a crime as his? To kill Lord Ashiel, that good, kind man who had treated him like a son all his life, who did everything for him. And just for the sake of money! It's not even as if he wanted it really. He's not starving. He had everything, in reason, that he wanted. If he needed more, urgently, I believe he had only to tell his uncle, and it would have been given to him. Oh, it is beyond all words! He must be a fiend."
Indignation choked her. She spoke in bursts of trembling anger, her words sounding tamely in her own ears. All she could say seemed commonplace and inadequate beside the knowledge that this man was her father's murderer.
Even Julia, indifferent to every aspect of the case that did not touch upon her relations with her lover, was shaken by the scornful disgust with which the broken sentences were poured forth; and, if her infatuation for Mark was too complete to allow her to consider any action of his unjustifiable, still she realized, perhaps for the first time, the feelings with which other people would view the thing that he had done.
"You don't understand him," she faltered. "He didn't want money for himself alone. It was for me he did it. He was too proud to ask me to marry a poor man. You could never understand his love for me. How can I blame him? How many men would run such risks for the girl they loved? I am proud, yes proud, to be loved like that!"
"You believe his lies," Juliet cried contemptuously. "You believe he loves you so much? Why it is not two days since he came to me and asked me to marry him."
"What!" Julia spoke in a panting whisper. Her face had suddenly lost every particle of colour. "Say it's not true," she begged, turning miserably to the man.
He made an effort to deny the charge.
"Of course. Not a word of truth in it. Damned nonsense," he blustered.
But his eyes fell before Juliet's scornful gaze, and Julia was not deceived.
"It can't be true, oh, it can't," she moaned. "No man could be so vile."
"No other man could," Juliet amended. In spite of herself she was sorry for the girl, whose stricken face showed plainly the anguish she was undergoing. "Forget him, Julia; he is not worthy to tie your shoe-lace. He came to me after they had taken David away, and asked me first if I would take his inheritance even though I couldn't prove my birth, which he must have known perfectly that I should never dream of doing, and then proposed I should marry him, saying that he was very fond of me, and that in that way justice would be done as regards Lord Ashiel's money, however things turned out for me. I thought it honourable and generous at the time, and so did Lady Ruth when I told her--oh yes, she knows about it and can tell you it is true--but now I see that all he wanted was to be on the safe side, and, if I had accepted him and had turned out to have no claim upon his uncle's fortune, he would have broken the engagement on some easy pretext. Can you deny it?" she demanded of Mark.
But he could not face her, though he made an effort again to brazen it out.
Every word she had spoken seemed to strike Julia like a blow. She shrank quivering away, and threw herself down on to a chair, her face hidden in her hands. Juliet went to her and touched her gently on the shoulder.
"Don't think of him any more," she said. "Presently you will hate yourself for having cared for a murderer. Just now, I know, your love for him makes you gloss over his crimes, but when you are yourself you will see how odious they are. Poor Julia, I hate to hurt you so, but it is better, isn't it, that you should know? You will forget this madness. He is not worth your wasting another thought on. Think how shamefully he has deceived you. Think of all his lying words, of how he told you he had never looked at another woman."
Julia raised her head and showed a face, white as chalk, in which the great brown eyes seemed to burn like fires of hatred.
"Yes," she said in a hard, even voice. "I am thinking of it. I shall not forget him. No. Instead, I shall think of him day and night, be sure of that. I shall laugh as I think of him; laugh at the thought of him in his place in the dock, or in his prison cell. I shall laugh when I give my evidence against him, and most of all I shall laugh on the day when he is hanged. If his grave is to be found, I shall dance upon it. Oh, it will be a merry day for me, that day when the cord is tightened round his false neck!"
She went near to Mark, and hissed the last words into his face, leaning forward, with one hand on her own throat. But he seemed to shrink less before her vindictive passion than he had under the colder scorn of Juliet's denunciations.
"Come, Juliet," said Julia, calming herself a little, although hate was still blazing in her eyes, "let us leave this place. We must send for the police."
"Julia," said Mark, stepping forward, and speaking with some of his former assurance, "you condemn me unheard. Why should you believe this girl before me? It is not like you, Julia. It is not like the girl I love. For I do love you, darling, in spite of what you may think; and, till a few moments ago, I thought you loved me too. But I see now what your love is. One whiff of suspicion, one word of accusation, and without proof or evidence you condemn me, and your so-called affection disappears. Julia, I think you have broken my heart."
Juliet gave vent to a derisive sound which can only be called a snort; but it was plain that his words, and more especially the manner of sad yet tender reproach in which they were uttered, were not without their effect on the other girl. Her eyes wavered uneasily; she twisted and tore at her handkerchief.
"I have heard what you have to say," she murmured. "I saw that you could not deny what Juliet told me."
"I did deny it. But what is the use of talking to you when you are in such a state? You are determined beforehand to disbelieve me. And I have no wish to justify myself to Miss Byrne, though I am willing to swallow my pride and do so to you."
"Well," she said after a moment's hesitation, "justify yourself if you can. No one shall say I would not listen. God knows I shall be glad enough if you can clear yourself."
"To begin with," said Mark, "I admit that, superficially, there is truth in what you have heard. But only superficially, for the person I deceived was not yourself but this young lady. I certainly, as she suggests, never had the slightest intention of marrying her. For one thing I was absolutely certain she would refuse me, but it seemed a good precautionary move to make what might appear a generous proposal, and at the same time get a sort of mandate from the possible heiress herself to stick to my uncle's fortune. You may be sure I should never have given it up, in any case, but it is as well to keep up appearances. The business was only a move in the game I am playing, and no more affects the sincerity of my love for you than any of the social equivocations we all find necessary from time to time. I love you, Julia, and you alone. How can you doubt it? I love you so much that I am willing to overlook your want of confidence in me, and to forgive the cruel things you said just now. Darling, how can I tell you, before a third person, what I feel for you? You are everything to me; and, if you no longer love me, I don't care what happens. Give me up to the police if you like. The gallows is as good a place as another, without your love."
Long before he had finished, all traces of resentment had vanished. When he ceased speaking, she gave in completely, and threw herself upon his breast, sobbing passionately, and begging his forgiveness for having doubted him for an instant, while he soothed and comforted her in a low tone. Juliet did not know what to do or which way to look. The two stood between her and the door, and she felt an absurd awkwardness about trying to pass them. Was it likely she would be allowed to go out free to denounce them? She was afraid of trying.
At last Julia was calm again, and there came a silence, during which the pair glanced at Juliet and then at each other.
"What's to be done?" Julia asked at length, and then suddenly, without waiting for an answer, "I have an idea, Mark, that will save you. If her mouth can be stopped for a time, will you be able to get clear away?"
"I shall have to try, I suppose," he replied, with a trace of his former sulkiness. "To think that everything should miscarry because of a slip of a girl!"
"You had better go to Glasgow and get on board some ship there which will take you to a place of safety. I shall have to stay behind till the matter of the list is settled one way or the other. But then, when I have reported to my superiors, I can join you, and we can begin life together in some far-off country. I shall be as happy in one place as in another with you, Mark; are you sure you will be, too, with only me?"
Mark hastened to reassure her on that point, but his tone as he said it did not carry conviction to Juliet. Julia, however, seemed satisfied.
"Miss Byrne can choose," she continued. "Either she swears not to say a word till we are both safe away, or else we can shut her in the dungeon of the castle. I know where it is, in the wall of this tower. She will never be found there, and I can take her food from time to time till I am ready to join you. Isn't that a good plan?"
Mark considered.
"I don't think we will give her the option of swearing not to tell," he said presently.
"As if I would ever promise such a thing!" Juliet interrupted, indignant.
"But," he went on, ignoring this outburst, "otherwise I think your idea is good. Where is this dungeon? We may be disturbed at any minute, and enough time has been wasted already."
"I will go first and show the way," said Julia. "I have an electric torch," and she stepped into the clock and lowered herself through the trap-door.
Mark motioned to Juliet to follow.
"Ladies first," he said with a sneer.
Juliet turned and made a dash for the door.
"I won't go! I won't! I won't!" she cried desperately, though in her heart she knew she could not resist if he chose to use force. Perhaps if she screamed, some one would hear. Oh, where was Gimblet? Why did he leave her to the mercy of these people? "Help! Help!" She lifted up her voice and shrieked as loud as she could.
With a vicious scowl Mark sprang upon her, and clapped a hand over her mouth. Then, as she still continued to produce muffled sounds of distress, he stuffed his handkerchief in between her teeth and, lifting her bodily in his arms, thrust her before him into the clock, and pushed her roughly down the hidden stair. Half-way down she lost her footing, and fell to the bottom, where Julia was standing with her little lamp in her hand.
Mark was following close behind, and between them they picked her up and hurried her, limping and bruised, along the narrow passage. She was allowed to take the handkerchief out of her mouth, for no cry could penetrate the immense thickness of these blocks of stone. At the point where there was a break to right and left in the walls of the passage, Julia came to a standstill.
"Here it is," she said, turning her light on to the opening in the wall on the left-hand side. "The door is gone, so you will have to fetch something to block it up with."
It seemed to be a small, cell-like chamber, built into the side of the tower. It may have contained a dozen cubic yards of space, and had neither door nor window.
"There are some slabs of stone at the end of the passage," said Julia. "They are heavy, but you are strong, you will be able to bring them. We must leave a little space at the top of the door to admit some air, and for me to pass food through to our prisoner." She laughed with a feverish merriment. "It will be like feeding the animals at the Zoo," she said.
Mark signified his approval by a nod.
"And is this the way?" he asked, turning round and starting off in the opposite direction.
"No, no!" Julie cried, laying a detaining hand upon his arm. "I don't know what there is down there. I think it is a well. See, you are on the very edge."
She cast the light on to a round dark opening in the ground some six feet in front of and below them. From where they stood the floor began to slant suddenly and steeply downward, so that if Mark had taken another step, it looked as if nothing could have prevented his sliding down into the gaping circle of blackness at the bottom.
Julia shuddered violently.
"Oh," she cried, "if you had gone over! Come away, do come away!"
"It's a funny sort of well," he said, "Looks to me like something else. Did you ever hear of oubliettes, Julia?"
Juliet, as she heard him, grew white with terror.
"Julia, Julia," she cried, "you won't let him throw me down there?"
"No, no," said Julia. "He would not. There is no reason.... Mark," she urged, "come away from here."
But he only laughed shortly.
"Don't be so hysterical," he said, and continued to bend his gaze upon the hole at the bottom of the slope. It seemed to have a sort of fascination for him. Finally he picked a piece of loose mortar from the wall and threw it down into the gap. A second later there was a dull sound which might have been a splash. "Perhaps it is a well after all. Did you think it sounded as if it had fallen into water?"
"Yes," said Julia, "I am sure it did. Do come away. I hate being here."
And indeed she was shivering from head to foot, and not Juliet herself seemed more anxious to leave the place.
"Just one more shot," said Mark. "Here, Julia, stoop down, and roll that bit of stone slowly down the slope, while I hold on to our prisoner. We shall hear better that way. Give me your lamp."
Anxious to satisfy him, Julia picked up the fragment he had knocked from the rough wall, and stooping down stretched out her hand to set the stone in motion. But, as she did so, Mark loosened his grip on Juliet, and bending quickly behind this poor girl who loved him seized her by the shoulders and threw her forward on to her face. The steep pitch of the floor finished what the impetus given by his onslaught had begun. Julia shot head first down the slope, and disappeared into the black chasm of the well.
One long agonized scream came up to them out of the darkness, and rolled its echoes through the lonely passages.
Then the distant sound of a splash; and silence.
Back against the wall, Juliet cowered, her whole body shaken by great sobs. She was petrified with terror of this fiendish man, but her fears for herself gave way before the horror of what she had seen.
"Oh, what have you done, what have you done?" she wept.
Mark tried to summon up a jeering smile. The lantern threw no light upon his white and twitching face.
"You don't suppose I meant to let her go free, after the taste she gave me of her temper?" he asked, in a voice he could not keep from shaking a little. "Do you suppose I like having to do these things? You women have never the slightest sense of common justice. The whole thing is perfectly beastly to me. But how could I live with a girl who would be ready to threaten me with the gallows every time she got out of bed wrong foot first? It's not fair to blame me for other people's faults."
He spoke querulously, with the air of a much-injured man. Though Juliet was beyond any coherent reply, he seemed afraid of meeting her eyes, and looked resolutely away from her, his glance shifting and wavering from the walls to the floor, from the floor to the stones of the low roof; up, down, and sideways, but never resting on her. At last, as if drawn there irresistibly and against his will, they fell once more on the dark circle of the mouth of the pit, and he started back, shuddering violently.
"As if I hadn't enough to bear without being saddled with hideous memories for the rest of my life!" he cried with bitter irritability. "If you had an ounce of common fairness in your composition you would admit I could do no less. Why, any day she might have got jealous, or something, and flown into a passion again, and denounced me to the police. Besides, I have no wish to be obliged to fly the country. Why should I? She was the only person who knew the truth; except you. That is why you must follow her."
"No, no!" cried Juliet despairingly, but without avail, for her feeble strength could offer him no effective opposition, and he thrust her easily on to the slope. She felt instinctively that at that angle the merest push would make her lose her balance, and sank quickly to her knees, catching him round the ankle with one hand, and clinging desperately.
He swore furiously, and bent down to unclasp her fingers from his leg. Then he flung her hand away from him; and cut off from all assistance she began instantly to slide backwards, slowly but irresistibly.
