Lawrence flicked the ash from his cigarette.

"I am," he said. "See, I am familiar with her plot before she carried it out. As I told you before, the whole thing is founded on a novel of mine which has yet to be published. How she got the thing is a mystery. But she has got it. It could not possibly have been a coincidence."

"If you know where she lives----" Charlton began.

"My dear sir, I know who she is. From the very moment that Bruce told his strange story I felt pretty certain that the Spanish business was a disguise."

"But it is no disguise. My wife's companion was a Spanish blonde."

"Then during the time that woman was in your house she wore a wig. You may make yourself pretty clear on that point. The creature you saw tonight in the courtyard has no doubt passed at different times under many names, but to the world she is at present known as Countess Lalage."

"I have heard of her. But she is very rich."

"So most people think. To my mind she is a brilliant adventuress. With beauty and brains and audacity a woman like that never need want for money. Of course, the crash will come sooner or later, but meanwhile she is having a good time. But you are going to see my patience rewarded. A murder has been committed here, and that woman knows all about it. Out of that murder came the terrible charge that hangs over my friend Bruce, and she knows all about that. I know all about it, too, but knowing and proving are two very different things. It is a fight in the dark between us, but I am going to win at the finish."

"You wouldn't force her to confess?"

"Not a woman like that. Get her back to the wall and she will be dangerous. Bless the man, if she knew I was her antagonist she would not hesitate to ask me to dinner and poison me over one of her excellent dishes. When I strike I must strike her down to the ground. My lines are laid pretty carefully, and she is going into them one by one. She walked into one of them tonight."
