"No, but maybe I understood a little more. I think that you saw everything that I did."

"I saw nothing remarkable except the bell-rope, and why that was put there is more than I can imagine."

"You saw the ventilator, too?"

"Yes, but I do not think that it is very unusual to have a small opening between two rooms. It was so small that a rat could hardly get through."

"I knew that we should find a ventilator before we came to Stoke Moran. You remember Miss Stonor said that her sister could smell Dr. Roylott's cigar. Now, of course, that told me at once that there must be a connection between the two rooms. It could only be a small one, or it would have been mentioned at the coroner's inquiry. I decided it was a ventilator. You must say that there is something a bit strange about the dates. A ventilator is made, a bell-rope is hung, and a lady who sleeps in the bed dies. Does not that seem rather strange to you?"
