"I!" Lopez stammered. "Do you mean to say——"

"You suggested it; you told Frobisher where the Blue Stone was. His quick brain did the rest. Now perhaps you begin to guess why I sent for you to-night."

"I thought perhaps you intended to help me," Lopez said with his eyes on the carpet.

"Why should I help you? To put money into your purse you did not hesitate to ruin me and my husband, knowing that my one poor vanity induced me to deck myself out in borrowed plumes. As a girl you asked for my heart and I gave it you; I gave all the love I had for any man. I have never been able to feel the same since. Don't flatter yourself that I care the least for you; the flower has been dead many years. I forgave you that. I did not get you crushed and broken, as I could easily have done. And now you dare drag me once again into your net. I sent for you to-night to make conditions; the whole truth must be told. You are to stay in London, and on Friday you are to give your evidence at the adjourned inquest."

"You are never going to have it all out?" Lopez said blankly.

"Indeed I am. Whether you and Frobisher are actually guilty of crime in the eyes of the law I don't know or care. But you both have a deal to answer for. Don't you play me false."

Lopez looked up and down again swiftly. He was thinking how he could turn this thing to advantage and go his own course at the same time. He did not hear the tinkle of the telephone-bell behind him; he took no heed as Mrs. Benstein placed the receiver to her ear.

"Yes," she said. "I am home. See you in ten minutes. Ask him to wait outside the drawing-room door. Oh, yes, the messenger came quite safely. Good night."

If Lopez heard all this it was quite in a mechanical way. He spoke presently, urging the uselessness of the proceedings that Isa Benstein suggested. She said something in reply, something cold and cutting, but she was taking no further interest in the matter. She was listening for something, the ring of the front-door bell and a step outside. It came at length, and she rose.

"My mind is quite made up," she said. "And I am not going to give you a chance to go back upon me. Will you open that door, please? I thank you. Inspector Townsend, will you be so good as to step in? As I told you over the telephone, the messenger arrived quite safely."
