“You won’t come back with me?”

“No, Miss Susie, I’ve serious work just now with the present lord of this manor; my future hangs on the issue. I’ll win—and I’ll come home later in the evening without a scratch.”

Again the slender white hand rested on his arm. “Promise me to wait an hour until you are cooler and your head is clear before you see him—will you?”

“Maybe,” he said evasively.

“If you do appreciate my coming,” she urged, “at least show it by this; promise for my sake, won’t you?”

He hesitated a moment and answered with courtesy:

“Yes, I promise for your sake, Susie, my little mascot and fellow conspirator of The Invisible Empire—good-bye!” He seized her hand, and held it a moment. “My! my! but you look one of us to-night, with that sylph figure robed in white standing there ghost-like in the moonlit shadows!”

“I wish I could share your dangers. I’d go on a raid with you if you’d let me,” she cried eagerly.

“No doubt,” he laughed.

“I’ll sit up until you come,” she whispered as she turned and left him.
