The girl took no notice of the interruption, but went on with her explanation to Henri Verbier.

"What happened was this: the rule is that I am at the disposal of customers, to take charge of deposits or to return them to the owners, until nine p.m., and until nine p.m. only. After that, my time is up, and all I have to do is lock my safe and go: I am free until nine o'clock next morning. You know that it does not do to take liberties in a position like mine. So when, on the day of the robbery, Mme. Van den Rosen came with her diamond necklace at half-past nine, I was perfectly within my rights in refusing to accept the deposit."

"That's right enough," said M. Muller, who, having finished his dessert, was now sipping coffee into which he had tipped sugar until it was as thick as syrup: "but you were disobliging, my dear young lady, and that was what struck the magistrate; for really it would not have been much trouble to register the new deposit and take charge of Mme. Van den Rosen's necklace for her."

"No, it wouldn't," the girl replied; "but when there is a rule it seems to me that it ought to be obeyed. My time is up at nine o'clock, and I am forbidden to accept any deposits after nine o'clock: and that's why I refused that lady's. I was perfectly right; and I should do the same again, if the same thing happened."

Henri Verbier was manifestly anxious to conciliate the young cashier. He expressed his approval of her conduct now.

"I quite agree with you, it never does to put interpretations upon orders. It was your duty to close your safe at nine o'clock, and you did close it then, and no one can say anything to you. But, joking apart, what did the magistrate want?"

The girl shrugged her shoulders with a gesture of indifference.

"You see I was right just now: M. Louis is only trying to tease me by saying that the magistrate cross-examined me severely. As a matter of fact I was simply asked what I have just told you, and when I gave all this explanation, no fault at all was found with me." As she spoke, Mlle. Jeanne folded her napkin carefully, pushed back her chair and shook hands with her two neighbours at table. "Good night," she said. "I am going up to bed."

Mlle. Jeanne had hardly left the room before Henri Verbier also rose from the table and prepared to follow her example.

M. Louis gave M. Muller a friendly dig in his comfortable paunch.
