"By Jove!" I exclaimed, with more irascibility than I intended to show. "If I succeed in doing all that is expected of me, I certainly will be entitled to more than an invitation to come and see you in New York."

She arose and laid her fingers upon my bandaged hand. The reckless light had died out of her eyes.

"I have thought that out, too, Mr. Smart," she said, quietly. "And now, good-bye. You will come up to see Mr. Bangs to-night?"

Considerably mystified by her remark, I said I would come, and then assisted her through the opening in the wall. She smiled back at me as the portrait swung into place.

What did she mean? Was it possible that she meant to have old man Titus reward me in a pecuniary way? The very thought of such a thing caused me to double up my fist—my recently discovered fist!—and to swear softly under my breath. After a few moments I was conscious of a fierce pain in the back of my hand.

Bangs was a shrewd little Englishman. As I shook hands with him—using my left hand with a superfluous apology—I glanced at the top of his waistcoat. There was no button missing.

"The Countess sewed it on for me," he said drily, reading my thoughts.

I stayed late with them, discussing plans. He had strongly advised against any attempt on Mrs. Titus's part to enter her daughter's hiding-place, but had been overruled. I conceived the notion, too, that he was a very strong-minded man. What then must have been the strength of Mrs. Titus's resolution to overcome the objections he put in her way?

He, too, had thought it all out. Everybody seems to have thought everything out with a single exception,—myself. His plan was not a bad one. Mrs. Titus and her sons were to enter the castle under cover of night, and I was to meet them in an automobile at a town some fifteen kilometers away, where they would leave the train while their watchers were asleep, and bring them overland to Schloss Rothhoefen. They would be accompanied by a single lady's maid and no luggage. A chartered motor boat would meet us up the river a few miles, and—well, it looked very simple! All that was required of me was a willingness to address her as "Mother" and her sons as "brothers" in case there were any questions asked.
