If Prince Bismarck or his big dog had come to town, there could not have been more excitement in the Bornholm family. The three young ladies sat upon a bed, with their hair done up in curl papers, and looked intense. They had hatched a plot of revenge which was worthy of three blonde heads done up in curl-paper. It had been ascertained that Mr. Grover had invited Miss Jones to the artists' carnival, and that Miss Jones had accepted the invitation. He had, moreover, asked the Frau Professorin to chaperone Miss Jones for the occasion, and the Frau Professorin, who was as fond of excitement as a girl, did not have the strength of mind to show him that she resented the slight he had put upon her daughters. She tried to make the daughters believe, of course, that she had; and they would undoubtedly have taken her word for it, if they hadn't been listening at the key-hole. When taken to task, the Frau Professorin was in such an indulgent mood that she would readily have consented to anything; and when Roeschen proposed that she, too, should go to the masquerade and in exactly the same costume as Miss Jones, her mother only interposed a vague demurrer which was easily overridden. The interesting complications which might arise, if Grover should mistake one Daughter of the Rhine for the other, stimulated her romantic fancy and made her eager as a girl to have the plot carried into effect. What was to be accomplished by it, she did not trouble herself to define; it only gave her a kind of confused satisfaction to think that she was mystifying somebody who had for a long time been mystifying her. Roeschen was exactly of Miss Jones's height and their figures closely resembled each other. So when they were masked a microscope would be required to tell them apart. Roeschen, who was full of blissful anticipations, went about during the day embracing people promiscuously from sheer excess of happiness. She could almost have embraced Grover, foe though he was, for having afforded her such a glorious opportunity for playing a trick on him. Her adventurous spirit had long yearned for some monumental enterprise, and this had somehow a mysterious atmosphere about it which made it doubly attractive to the admirer of Lucrezia Borgia. As for Miss Jones, she was unsuspicious as a new-born babe, which circumstance heightened the joy of the conspirators, thrilling them with sensations of deep and delightful villainy.
