Phelps pulled the bell cord in his office to summon the commissionaire, and to his surprise the commissionaire's wife came up instead. He worked at copying the treaty that he had been given while he waited. At last, he went to see the commissionaire when it had taken some time for the coffee to arrive. He found him asleep with the kettle boiling furiously. He did not need to wake him up, however, as just then, the bell linked to his office rang. Realizing that someone was in his office with the treaty still spread out on his desk, Phelps rushed back up and found that the document had vanished, as had the thief.
