For reasons best known to himself, he failed to respond to this interesting confession. He was thinking of something else: his amazing stupidity in not foreseeing the very situation that now presented itself. Why had he neglected to settle upon a meeting place with Sprouse in the event that circumstances forced them to part company in flight? Fearing that she would pursue the subject, he made haste to branch off onto another line.
"What is the real object of the conspiracy up there, Miss Cameron?"
"You must bear with me a little longer, Mr. Barnes," she said, appealingly. "I cannot say anything now. I am in a very perplexing position. You see, I am not quite sure that I am right in my conclusions, and it would be dreadful if I were to make a mistake."
"If they are up to any game that may work harm to the Allies, they must not be allowed to go on with it," he said sternly. "Don't wait too long before exposing them, Miss Cameron."
"I--I cannot speak now," she said, painfully.
"You said that to-morrow night would be too late. What did you mean by that?"
"Do you insist on pinning me down to--"
"No. You may tell me to mind my own business, if you like."
"That is not a nice way to put it, Mr. Barnes. I could never say such a thing to you."
He was silent. She waited a few seconds and then removed her head from his shoulder. He heard the sharp intake of her breath and felt the convulsive movement of the arm that rested against his. There was no mistaking her sudden agitation.
"I will tell you," she said, and he was surprised by the harshness that came into her voice. "To-morrow morning was the time set for my marriage to that wretch up there. I could have avoided it only by destroying myself. If you had come to-morrow night instead of to-night you would have found me dead, that is all. Now you understand."
"Good God! You--you were to be forced into a marriage with--why, it is the most damnable--"
"O'Dowd,--God bless him!--was my only champion. He knew my father. He--"
"Listen!" he hissed, starting to his feet.
"Don't move!" came from the darkness outside. "I have me gun leveled. I heard me name taken in vain. Thanks for the blessing. I was wondering whether you would say something pleasant about me,--and, thank the good Lord, I was patient. But I'd advise you both to sit still, just the same."
A chuckle rounded out the gentle admonition of the invisible Irishman.
