As Eveline Mandeville had mentioned the circumstance of having overheard the conversation between the two worthies, related, in the first chapter, to no one but her father, it becomes a matter of curiosity to know how Duffel had come in possession of the secret.  A very few words will explain the matter.  Like most persons who feel a consciousness of want of rectitude of purpose, he felt desirous to learn what other people thought of him, fearing his evil intentions might possibly manifest themselves in some manner unnoticed by himself; and as he had most at stake with the Mandevilles, he was proportionally more interested in the opinions they might entertain respecting his life and character, than in those of any others.  He accordingly resorted to the mean and cowardly expedient of eavesdropping, in order to gain a knowledge of the standing he occupied in the estimation of this family, particularly with regard to the father and daughter.  He would approach the house unobserved and listen at some point, to overhear the conversations that took place in the family circle!

After long and deep thought, during which scheme after scheme was suggested to his mind, turned over, examined, and abandoned, he finally hit upon an expedient that suited his purpose exactly, and at once resolved to act upon it.  For this purpose he sought and obtained a private interview with Mr. Mandeville, as already intimated, in which he began the development of his plot as follows: 

“I have sought this interview with no idle purpose, Mr. Mandeville,” he began.  “You are already aware of the deep interest I feel in your daughter, and how intimately my future happiness is interwoven with her good opinion.  That good opinion, I have the best of evidence to believe, is being undermined by one to whom you have ever been kind, but who, I am sure, you would not wish to become your son-in-law, though he has the audacity—­if I may be
