"Mrs. Mansfield lives alone," he went on. "She has three coloured servants, two maids and a man."

"Did you find out where they slept?"

"Yes. The two maids on the top floor in the front room, the man somewhere in the basement."

"Are they in the gang?"

"No. They do not know that Miss Farrell is in the house. But the man, I understood, could be depended on absolutely. Which means that he is ready for any black deed. He is as ugly and strong as a gorilla."

"What about the other internal arrangements of the house?"

"On the first floor there is a parlour in front, dining-room and pantry behind. On the second floor the front room is a sitting-room or office. The telephone is here. Mrs. Mansfield sleeps in the rear room on this floor. Between her bedroom and the office there is an interior room, and that is where Miss Farrell is confined. This room can be entered only through Mrs. Mansfield's bedroom."

"Did you notice the locks on the doors?"

"No. There was nothing out of the common. On the front door a Yale lock of the ordinary pattern."

"Anything more?"
