"I do not know."

"Will you swear then that you never spoke to him of the Prince of Orange, and of our plans?"

"Not of your plans ..." she protested calmly.

"You see that you cannot deny it, Gilda," he continued with that same unnatural calm which seemed to her far more horrible than his rage had been before. "Willingly or unwittingly you let that man know what you overheard in the Groote Kerk on New Year's Eve. Then you bribed him into warning the Prince of Orange, since you could not do it yourself."

"It is false," she reiterated wildly.

Once more that evil sneer distorted his pale face.

"Well!" he said, "whether you bribed him or not matters to me but little. I do believe that willingly you would not have betrayed Nicolaes or me or any of our friends to the Stadtholder, knowing what he is. But you wanted to cross our plans, you wanted to warn the Stadtholder of his danger, and you—not God—chose that man for your instrument."

"It is not true—I deny it," she repeated fearlessly.

"You may deny it with words, Gilda, but your whole attitude proclaims the truth. Thank God!" he cried with a note of savage triumph in his voice, "that man is still a helpless prisoner in my hands."

"What do you mean?" she murmured.
