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.
