“What was it that interested you so much?” asked Nick. “Something you saw in the street?”
“No, something I saw in a window across the street.”
“What did you see?”
“A woman.”
“Why did the woman prove so interesting?”
“Because from her actions I thought she was watching something which was going on in this building.”
“Ah! now we are getting at something important. What made you believe she was watching this building?”
“Because when she first came to that window she looked out boldly, fearlessly and carelessly; suddenly she drew back and hid her face behind the edge of the window, seemingly on the watch and anxious not to be noticed herself.”
“Well?”
“She sat thus probably five minutes. Then, springing to her feet, she almost ran away from the window and disappeared.”
