“It leads down to the room where I saw the light, doesn’t it?”

“Not exactly. There is a hole in the ceiling. I made it with a knife. You see, I didn’t know how soon I would be wanting to find out something about my neighbors, so I haven’t been idle.”

“You’re worth your weight in gold, Clara.”

In a little while Carter found himself in another dark place, and Clara pointed to a ray of light that seemed to come up from some place under their feet, and the detective drew closer.

“Put your eye down to it,” said the woman.

This Nick did, and soon became accustomed to the scene beneath him.

He was looking into a large and expensively furnished room.

Pictures in large gilt frames were arranged on the walls, and thick Brussels carpet covered the floor.

The chandeliers were of expensive make, and everything betokened great wealth.

The room was inhabited at the time by a man who reclined in an armchair under the main light.
