"One thing. Mrs. Mansfield goes armed. She has a small automatic pistol with a maxim silencer which is evidently her favourite toy. I hope I got what you wanted. They were at me every minute. I could not look around much."

"No one could have done better!" I said heartily.

"What do you want me to do now?"

"Where are you?"

"In my own boarding-house. The party at the Turtle Bay soon broke up. The telephone here is in the restaurant in the basement, and everybody sleeps upstairs."

"You had better stay at home until morning," I said, after thinking a moment. "It is very likely that they are having you watched to-night."

"But I must do something. I couldn't sleep."

"There is really nothing you can do now. Stay where you can hear the telephone and I'll call you if I need you. I'll call you anyway when I get her out safe. If you do not hear from me by say, three o'clock, go to police headquarters, tell them all the circumstances, and have the house surrounded and forced."

"I understand."

"To-morrow morning if all goes well, you must go to work as usual. I don't mean that we shall lose all our work so far if I can help it. They must not suspect you."
