“The odds are that she’s old and ugly. Patti herself, you know, is upwards of forty. It isn’t probable that with her marvelous musical accomplishments, this lady is endowed with youth and beauty also. I wouldn’t cherish great expectations of her, if I were you; because then, if you should ever chance to see her, you’ll be so much disappointed. Better make up your mind that her attractions begin and end with her voice. Complexion? Did you ask my opinion of her complexion? Oh, she’s blonde—that goes without saying.”

“Wrong again! She’s a brunette of the first water; dusky skin, red mouth, black, lustrous eyes. You can tell that from the fire she puts into her music. As for her age, you’re doubly mistaken. If you had the least faculty for adding two and two together—arithmetician that you are—you’d know at once that a voice of such freshness, such compass, and such volume, could not pertain to a woman far beyond twenty. On the other hand, no mere school-girl could sing with such intelligent expression. Wherefore, striking an average, I’ll venture she’s in the immediate vicinity of twenty-five. However, conjectures are neither here nor there. Where’s Josephine? Let’s have her up, and interrogate her.”

With this speech, Arthur began to pound his heel upon the roof—the method which these young bachelors employed to make known to their domestic that her attendance was wanted. When the venerable Josephine had emerged waist-high from the scuttle-door, “Josephine,” demanded Arthur, “who is the new tenant of the corner house?”

But Josephine could not tell. Indeed, she was not even aware that the corner house had been taken. Arthur set her right on this score, and, “Now,” he continued, “I wish you would gossip with the divers and sundry servants of the neighborhood until you have found out the most you can about these new-comers, and then report to me. For this purpose, you are allowed an evening’s outing. But as you prize my good-will, be both diligent and discreet.”

As the twilight deepened into darkness, Arthur remained posted at the roof’s edge, looking wistfully over toward the third-story windows of the corner house. By and by a light flashed up behind them; but the next instant an unseen hand drew the shades; and a few moments later the light was extinguished.

“They retire early,” he grumbled.

“By the way, don’t you think it’s getting a little chilly up here?” asked Hetzel.

“Decidedly,” he assented, shivering. “Shall we go below?”

They descended into their sitting-room—a cozy, book-lined apartment, with a permanent savor of tobacco smoke upon its breath—and chatted together till a late hour. The Peixada matter and the mysterious songstress of No. 46 pretty equally divided their attention.

Next morning Hetzel—whose bed-chamber, at the front of the house, overlooked the street; whereas Arthur’s, at the rear, overlooked the river—Hetzel was awakened by a loud rap at his door.
