"In my experience of the world," Mrs. Wagner went on, "I have found that the rarest of all human virtues is the virtue of gratitude. In a hundred little ways my poor friendless Jack has shown me that he is grateful. To my mind that is reason enough for trusting him."
"With money?" the widow inquired.
"Certainly. In London I trusted him with money—with the happiest results. I quieted his mind by an appeal to his sense of trust and self-respect, which he thoroughly appreciated. As yet I have not given him the key of my desk here, because I reserve it as a special reward for good conduct. In a few days more I have no doubt he will add it to the collection in his bag."
"Ah," said Madame Fontaine, with the humility which no living woman knew better when and how to assume, "you understand these difficult questions—you have your grand national common-sense. I am only a poor limited German woman. But, as you say in England, 'Live and learn.' You have indescribably interested me. Good morning."
She left the room. "Hateful woman!" she said in her own language, on the outer side of the door.
"Humbug!" said Mrs. Wagner in her language, on the inner side of the door.
If there had been more sympathy between the two ladies, or if Madame Fontaine had felt a little curiosity on the subject of crazy Jack's keys, she might have taken away with her some valuable materials for future consideration. As it was, Mrs. Wagner had not troubled her with any detailed narrative of the manner in which she had contrived to fill Jack's leather bag.
In London, she had begun cautiously by only giving him some of the useless old keys which accumulate about a house in course of years. When the novelty of merely keeping them had worn off, and when he wanted to see them put to some positive use, she had added one or two keys of her own, and had flattered his pride by asking him to open the box or the desk for her, as the case might be. Proceeding on the same wisely gradual plan at Frankfort, she had asked Mr. Keller to help her, and had been taken by him (while Jack was out of the way) to a lumber-room in the basement of the house, on the floor of which several old keys were lying about. "Take as many as you like," he had said; "they have been here, for all I know, ever since the house was repaired and refurnished in my grandfather's time, and they might be sold for old iron, if there were only enough of them." Mrs. Wagner had picked up the first six keys that presented themselves, and had made Jack Straw the happiest of men. He found no fault with them for being rusty. On the contrary, he looked forward with delight to the enjoyment of cleaning away the rust. "They shall be as bright as diamonds," he had said to his mistress, "before I have done with them."
And what did Madame Fontaine lose, by failing to inform herself of such trifles as these? She never discovered what she had lost. But she had not done with Jack Straw yet.
