"That will be best," nodded Marjorie. Nevertheless, she reflected that as a member of the chorus she would have opportunity to observe the French girl and mentally decided to keep an eye on her.

"Has Mary come in, Delia?" was Marjorie's quick question, as the maid answered her ring.

"Here I am," called Mary from the living room. She had heard Marjorie's question. Now she appeared in the doorway of the living room, viewing her former chum with sombre gravity. "Who is going to sing the Princess?" she asked abruptly.

"Connie was chosen. She sang beautifully."

"I'm glad Mignon didn't get the part," muttered Mary. Wheeling about, she walked into the living room, and, taking up a book she had turned face downward on the table, became, to all appearances, absorbed in its pages.

For a moment Marjorie stood watching her through the half-drawn portieres. She would have liked to continue the conversation, but pride forbade her to do so. Mary's mood presaged rebuff. Later, at luncheon, she unbent sufficiently to question Marjorie further regarding the try-out. Although she did not say so, she was sorry that Mignon had been given a principal's part in the operetta. Privately, she wished she had made an attempt to get into the chorus. She, too, was of the opinion that the French girl would bear watching. Failure to carry off the highest honors would act as a spur to Mignon's unscrupulous nature, and sooner or later some one would pay for her defeat.

Mary was quite correct in her conjecture that Mignon would not allow matters to rest as they were. From the moment that Constance had been announced as the Princess she had made a vow that by either fair or unfair means she would supplant "that white-faced cat of a Stevens girl," who had been awarded the honor that should have been hers. The first step consisted in holding a private session with Professor Harmon after the others had gone, to ascertain if by any chance he might be relied upon to help her. She found him engaged in conversation with the dark young man. He eyed her with interest, bowed affably when presented to her by the professor, and expressed somewhat profuse pleasure at meeting her. In the presence of a stranger, Mignon dared not ask Professor Harmon openly to reconsider his recent decision in her favor. Three minutes' conversation with him showed her that, had she made the request, it would have availed her nothing. The brisk little man's mind was made up. He congratulated her on capturing second honors with a finality that could not be assailed. Then a brilliant idea entered her wily brain.

"Professor Harmon," she began, with a pretty show of girlish confusion, quite foreign to her usual bold method of reaching out for whatever she coveted, "I would like to ask you if I might understudy the Princess. Of course, I know that I can't sing as Miss Stevens sings, and I wouldn't for the world wish anything to happen to prevent her from singing on the great night, but I am so fond of music that it would be a pleasure to understudy the rôle. I shouldn't like anyone to know that I was doing so, though. It is just a fancy on my part."

"Certainly you may, Miss La Salle," was the professor's hearty response. "Your idea is excellent. It is a mistake, even in an amateur production, not to provide an understudy for an important rôle, such as Miss Stevens will sing. I must provide an understudy for Mr. Macy, and others of the cast, also. But you are too modest in your request that no one else must know. I am sure Mr. Armitage will be pleased with your suggestion."

"Oh, please don't tell him!" exclaimed Mignon. A shade of alarm crossed her dark face, which was not lost on the professor's companion, Ronald Atwell. A mere acquaintance of Professor Harmon's, he had lately arrived in Sanford, at the close of a season as leading man in a popular musical comedy, to visit a cousin. Brought up in that hard school of experience, the stage, he was an adept at reading signs, and he was by no means deceived as to the true character of the girl who stood before him. Far from being displeased with his deductions, he became mildly interested in her and mentally characterized her as being worth cultivating. He had watched her during the try-out, and he had glimpsed her true self in the varying expressions that animated her dark face. He had attended the try-out on the polite invitation of Professor Harmon, and at the latter's earnest solicitation had agreed to take charge of the stage direction of the operetta. The professor had congratulated himself on obtaining such valuable assistance, while the actor looked upon the affair as a pastime which would serve to lighten his stay with his rather dull cousin. He had come to Sanford for a period of relaxation before going to New York to begin rehearsals with a summer show, and the prospect of directing the operetta promised to be amusing.
