"No. But maybe I understood a little bit more. I think that you saw everything that I saw."

"There was nothing interesting except the bell-rope. I really do not understand why Dr Roylott put that bell-rope there."

"Did you see the ventilator?"

"Yes, but I do not think that it is very unusual to have a small opening between two rooms. The ventilator was so small that only a mouse could get through."

"I knew that there a ventilator even before we came here. Miss Stonor told us that her sister could smell Dr. Roylott's cigar. Now, of course this means that there is a connection between the two rooms.

It couldn't be a big opening, or the people who tried to find out how the sister died would have looked at it. I decided it was a ventilator. There is something a bit strange about when things happened. A ventilator is made, a bell-rope is hung, and a lady who sleeps in the bed dies. Don't you think that is a bit strange?"
