If that were so, how was it that Mademoiselle had been attacked after?
or rather, that she appeared to have been attacked after?
It was necessary for me to reconstruct the occurrence and make of it two phases--each separated from the other, in time, by the space of several hours.

One phase in which Mademoiselle Stangerson had really been attacked--the other phase in which those who heard her cries thought she was being attacked.

I had not then examined The Yellow Room.

What were the marks on Mademoiselle Stangerson?
There were marks of strangulation and the wound from a hard blow on the temple.

The marks of strangulation did not interest me much; they might have been made before, and Mademoiselle Stangerson could have concealed them by a collarette, or any similar article of apparel.
