After a short silence he added:—
“Ah—if Mademoiselle Stangerson were only well enough to-day to allow of her being questioned!”
Rouletabille following up his thought, asked:—
“And the attic?—There must be some opening to that?”
“Yes; there is a window, or rather skylight, in it, which, as it looks out towards the country, Monsieur Stangerson has had barred, like the rest of the windows. These bars, as in the other windows, have remained intact, and the blinds, which naturally open inwards, have not been unfastened. For the rest, we have not discovered anything to lead us to suspect that the murderer had passed through the attic.”
“It seems clear to you, then, Monsieur, that the murderer escaped—nobody knows how—by the window in the vestibule?”
“Everything goes to prove it.”
“I think so, too,” confessed Rouletabille gravely.
After a brief silence, he continued:—
“If you have not found any traces of the murderer in the attic, such as the dirty footmarks similar to those on the floor of The Yellow Room, you must come to the conclusion that it was not he who stole Daddy Jacques’s revolver.”
