“It may cause him to be more cautious, or it may drive him to desperate measures at once. Like most clever criminals, he may be too confident in his own cleverness and imagine that he has completely deceived us.”	— Elle peut le rendre plus prudent ou, au contraire, le pousser à la témérité. Comme la plupart des criminels habiles, il est capable de trop compter sur son habileté et de croire qu’il nous a dupés.
