`` I 'm going right away , '' said Nick . `` All I want of you is that you will give me your address , and meet me at your home in the latter part of the afternoon . '' `` Very well , '' said Jones , and he scribbled on a piece of paper . `` I 'll be there at half-past four o'clock . '' Nick thanked Mr. Jones for his courtesy , and immediately withdrew . But he did not go far . In a convenient doorway he wrote a note to Chick , on the back of the scrap of paper which Jones had given him , and sealed it in an envelope .
