The Diamond Master

There were thirty or forty personally addressed letters, the daily heritage of the head of a great business establishment; and a plain, yellow-wrapped package about the size of a cigarette-box, some three inches long, two inches wide and one inch deep. It was neatly tied with thin scarlet twine, and innocent of markings except for the superscription in a precise, copperplate hand, and the smudge of the postmark across the ten-cent stamp in the upper right-hand corner. The imprint of the cancellation, faintly decipherable, showed that the package had been mailed at the Madison Square substation at half-past seven o'clock of the previous evening.
