Gaston Leroux,
The Mystery of the Yellow Room
“ Who could believe that the letter which had so recently been on the table in her room would no longer be there? He who could understand all this, would have to assume that Mademoiselle Stangerson knew that the murderer was coming—she could not prevent his coming again—unknown to her father, unknown to all but to Monsieur Robert Darzac. For he must know it now—perhaps he had known it before! Did he remember that phrase in the Élysée garden: ‘Must I commit a crime, then, to win you?’ Against whom the crime, if not against the obstacle, against the murderer? ”
