"Emeralds; they're your good luck stones. You will go to the box before I do. I've got to spend some time at the curb to be sure that this Servan chap arrives. And it is quite possible that our friend Jones will come later. If not Jones, then Norton. I was a fool not to shoot him when I had the chance. We could have covered it up without the least difficulty. But I needed the information about that paper.

Be at the opera at eight-thirty. Pay no attention to any one; wait for me. Remember, I shan't write or send any phone messages. Be wary of any trap like that to get you outside. Now, I'm off."

Jones approached Florence immediately after dinner.

"I have important business in the city to-night. Under no circumstances leave the house. I shall probably be followed. And our enemies will have need of you far more to-night than at any previous time. I shall not send you phone or written message. You have your revolver. Shoot any strange man who enters.
