"Do you remember the window from which he threw this object?" The detective looked at her anxiously.
"Yes, indeed, it is easy to remember; it's the end window, on the first floor of the hotel. There!"
Coquenil felt a thrill of excitement, for, unless he had misunderstood the commissary's diagram, the seamstress was pointing not to private room Number Six, but to private room Number Seven!
"Lucien!" he called, and, taking his friend aside, he asked: "Does that end window on the first floor belong to Number Six or Number Seven?"
"Number Seven."
"And the window next to it?"
"Number Six."
"Are you sure?"
"Absolutely sure."
"Thanks. Just a moment," and he rejoined the seamstress.
