As he spoke, the chief bookkeeper, who had the treble advantage of being tall, pretty, and just eight-and-twenty years of age, entered the room. She noticed the open letter and the look upon her chief's face, and her curiosity was proportionately excited.

"You seem worried, Mr. McPherson," she said tenderly, as she put down the papers she had brought in for his signature.

"You have just hit it, Miss O'Sullivan," he answered, pushing them farther on to the table. "I am worried about many things, but particularly about this letter."

He handed the epistle to her, and she, being desirous of impressing him with her business capabilities, read it with ostentatious care. But it was noticeable that when she reached the signature she too turned back to the beginning, and then deliberately read it over again. The manager rose, crossed to the mantelpiece, and rang for the head waiter. Having relieved his feelings in this way, he seated himself again at his writing-table, put on his glasses, and stared at his companion, while waiting for her to speak.

"It's very funny," she said. "Very funny indeed!"

"It's the most extraordinary communication I have ever received," he replied with conviction. "You see it is written from Cuyaba, Brazil. The date is three months ago to a day. Now I have taken the trouble to find out where and what Cuyaba is."

He made this confession with an air of conscious pride, and having done so, laid himself back in his chair, stuck his thumbs into the armholes of his waistcoat, and looked at his fair subordinate for approval. Nor was he destined to be disappointed. He was a bachelor in possession of a snug income, and she, besides being pretty, was a lady with a keen eye to the main chance.

"And where is Cuyaba?" she asked humbly.

"Cuyaba," he replied, rolling his tongue with considerable relish round his unconscious mispronunciation of the name, "is a town almost on the western or Bolivian border of Brazil. It is of moderate size, is situated on the banks of the river Cuyaba, and is considerably connected with the famous Brazilian Diamond Fields."

"And does the writer of this letter live there?"
