In the courtyard of his house he saw two little puppies which belonged to the coachman and which were generally confined to the stables. They were playing with a twist of red string which kept catching on to things, to the railings of the steps, to the flower vases. In the end, the paper round which the string was wound, appeared. Don Luis happened to pass at that moment. His eyes noticed marks of writing on the paper, and he mechanically picked it up and unfolded it.
He gave a start. He had at once recognized the opening lines of the article printed in the Echo de France. And the whole article was there, written in ink, on ruled paper, with erasures, and with sentences added, struck out, and begun anew.
He called the coachman and asked him:
"Where does this ball of string come from?"
"The string, sir? Why, from the harness-room, I think. It must have been that little she-devil of a Mirza who—"
"And when did you wind the string round the paper?"
"Yesterday evening, Monsieur."
"Yesterday evening. I see. And where is the paper from?"
"Upon my word, Monsieur, I can't say. I wanted something to wind my string on. I picked this bit up behind the coach-house where they fling all the rubbish of the house to be taken into the street at night."
Don Luis pursued his investigations. He questioned or asked Mlle. Levasseur to question the other servants. He discovered nothing; but one fact remained: the article in the Echo de France had been written, as the rough draft which he had picked up proved, by somebody who lived in the house or who was in touch with one of the people in the house.
