"I am to leave then tomorrow night?"

"Yes, over the Eastern Illinois, at 8:10."

There was a moment's silence; then he rustled the paper on the table, and held out a fountain pen.

"Sign here."

I was not hypnotized, or unduly controlled; my mind seemed clear, but I yielded without a word and wrote my name at the bottom of the sheet. Vail blotted it carefully, folded the paper, and placed it in a drawer of the table. Then he handed me two bills.

"There is a thousand dollars there, Craig, and I will send you a typewritten memoranda of instructions, covering all points in the game. Where can I be sure of finding you at three o'clock tomorrow?"

"At 407 Green Street."

"All right; as soon as you read those instructions call me up by 'phone, and let me know what you have done regarding a woman, and ask any questions you may desire. That will be all now. Neale, you might show Craig the way out."

He put out his arm, and we shook hands, although he did not arise from the chair. It had all been accomplished so suddenly that I felt confused, uncertain as to what I had best do. Only the feel of those bills in my pocket seemed real, and made me fully aware that I was pledged to the service. Neale stepped into the hall, and I followed him. The entry way was in darkness, and the man went to the side door without switching on the light.

"Is this Mr. Vail's house?" I questioned, and he drew the latch.
