“What was really foolish, madame, is that you have placed yourself in the power of a band of rascals who may blackmail or give you away.”

“No, no! I am not so simple. Since I have promised to be frank, I may say that no one, save Barney Stockdale and Susan, his wife, have the least idea who their employer is. As to them, well, it is not the first- -” She smiled and nodded with a charming coquettish intimacy.

“I see. You’ve tested them before.”

“They are good hounds who run silent.”

“Such hounds have a way sooner or later of biting the hand that feeds them. They will be arrested for this burglary. The police are already after them.”

“They will take what comes to them. That is what they are paid for. I shall not appear in the matter.”

“Unless I bring you into it.”

“No, no, you would not. You are a gentleman. It is a woman’s secret.”

“In the first place, you must give back this manuscript.”

She broke into a ripple of laughter and walked to the fireplace. There was a calcined mass which she broke up with the poker. “Shall I give this back?” she asked. So roguish and exquisite did she look as she stood before us with a challenging smile that I felt of all Holmes’s criminals this was the one whom he would find it hardest to face. However, he was immune from sentiment.

“That seals your fate,” he said coldly. “You are very prompt in your actions, madame, but you have overdone it on this occasion.”

She threw the poker down with a clatter.

“How hard you are!” she cried. “May I tell you the whole story?”

“I fancy I could tell it to you.”

“But you must look at it with my eyes, Mr. Holmes. You must realize it from the point of view of a woman who sees all her life’s ambition about to be ruined at the last moment. Is such a woman to be blamed if she protects herself?”

“The original sin was yours.”

“Yes, yes! I admit it. He was a dear boy, Douglas, but it so chanced that he could not fit into my plans. He wanted marriage - marriage, Mr. Holmes - with a penniless commoner. Nothing less would serve him. Then he became pertinacious. Because I had given he seemed to think that I still must give, and to him only. It was intolerable. At last I had to make him realize it.”

“By hiring ruffians to beat him under your own window.”

“You do indeed seem to know everything. Well, it is true. Barney and the boys drove him away, and were, I admit, a little rough in doing so. But what did he do then? Could I have believed that a gentleman would do such an act? He wrote a book in which he described his own story. I, of course, was the wolf; he the lamb. It was all there, under different names, of course; but who in all London would have failed to recognize it? What do you say to that, Mr. Holmes?”

“Well, he was within his rights.”

“It was as if the air of Italy had got into his blood and brought with it the old cruel Italian spirit. He wrote to me and sent me a copy of his book that I might have the torture of anticipation. There were two copies, he said - one for me, one for his publisher.”

“How did you know the publisher’s had not reached him?”
