"Of course, I immediately thought that they both knew everything, but she seemed so calm and quiet, that I set aside my suspicions, and thought it was only some strange coincidence, as I could not believe in such dissimulation on her part, and so, after half-an-hour's friendly talk, which was, however, interrupted a dozen times by her little girl coming in and out of the room. I went away, very much annoyed. Just imagine the next day...." "The same thing happened?" "Yes, and the next also. And that went on for three weeks without any explanation, without anything explaining that strange conduct to me, the secret of which I suspected, however." "They knew everything?" "I should think so, by George. But how? Ah! I had a great deal of anxiety before I found it out." "How did you manage it at last?" "From their letters, for on the same day they both gave me their dismissal in identical terms." "Well?" "This is how it was.... You know that women always have an array of pins about them. I know hairpins, I doubt them, and look after them, but the others are much more treacherous; those confounded little black-headed pins which look all alike to us, great fools that we are, but which they can distinguish, just as we can distinguish a horse from a dog. "Well, it appears that one day my minister's little wife left one of those tell-tale instruments pinned to the paper, close to my looking-glass. My usual one had immediately seen this little black speck, no bigger than a flea, and had taken it out without saying a word, and then had left one of her pins, which was also black, but of a different pattern, in the same place. "The next day, the minister's wife wished to recover her property, and immediately recognized the substitution. Then her suspicions were aroused, and she put in two and crossed them, and my original one replied to this telegraphic signal by three black pellets, one on the top of the other, and as soon as this method had begun, they continued to communicate with one another, without saying a word, only to spy on each other. Then it appears that the regular one, being bolder, wrapped a tiny piece of paper round the little wire point, and wrote upon it: _C. D., Poste Restante, Boulevards, Malherbes_. "Then they wrote to each other. You understand that was not everything that passed between them. They set to work with precaution, with a thousand stratagems, with all the prudence that is necessary in such cases, but the regular one did a bold stroke, and made an appointment with the other. I do not know what they said to each other; all that I know is, that I had to pay the costs of their interview. There you have it all!" "Is that all?" "Yes." "And you do not see them any more?" "I beg your pardon. I see them as friends, for we have not quarreled altogether." "And have they met again?" "Yes, my dear fellow, they have become intimate friends." "And has not that given you an idea?" "No, what idea?"
