Rosalie fell sobbing bitterly upon a chair; the mouse did not stir. A few moments afterwards, Prudent entered hastily, his countenance marked with horror.

"Rosalie! unhappy child! what have you done? You have yielded to your fatal curiosity and released our most cruel enemy from prison."

"Pardon me, father! oh pardon me!" she cried, throwing herself at his feet; "I was ignorant of the evil I did."

"Misfortune is always the result of disobedience, Rosalie; disobedient children think they are only committing a small fault, when they are doing the greatest injury to themselves and others."

"But, father, who and what then is this mouse, who causes you this terrible fear? How, if it had so much power, could you keep it so long a prisoner and why can you not put it in prison again?"

"This mouse, my unhappy child, is a wicked fairy, but very powerful. For myself, I am the genius Prudent and since you have given liberty to my enemy, I can now reveal to you that which I should have concealed until you were fifteen years old.

"I am, then, as I said to you, the genius Prudent; your dear mother was a simple mortal but her virtues and her graces touched the queen of the fairies and also the king of the genii and they permitted me to wed her. I gave a splendid festival on my marriage-day. Unfortunately I forgot to invoke the fairy Detestable, who was already irritated against me for having married a princess, after having refused one of her daughters. She was so exasperated against me that she swore an implacable hatred against me, my wife and my children. I was not terrified at her threats, as I myself had a power almost equal to her own and I was much beloved by the queen of the fairies. Many times by the power of my enchantments, I triumphed over the malicious hatred of the fairy Detestable.

"A few hours after your birth your mother was thrown into the most violent convulsions which I could not calm. I left her for a few moments to invoke the aid of the queen of the fairies. When I returned your mother was dead.

"The wicked fairy Detestable had profited by my absence and caused her death. She was about to endow you with all the passions and vices of this evil world, when my unexpected return happily paralyzed her efforts. I interrupted her at the moment when she had endowed you with a curiosity sufficient to make you wretched and to subject you entirely to her power at fifteen years of age. By my power, united to that of the queen of the fairies, I counter-balanced this fatal influence and we decided that you should not fall under her power at fifteen years of age, unless you yielded three times under the gravest circumstances to your idle curiosity.

"At the same time the queen of the fairies, to punish the fairy Detestable, changed her into a mouse, shut her up in the little garden house, and declared that she should never leave it unless you voluntarily opened the door. Also, that she should never resume her original form of fairy unless you yielded three times to your criminal curiosity before you were fifteen years of age. Lastly, that if you resisted once the fatal passion you should be for ever released, as well as myself, from the power of the fairy Detestable.
