It occasionally happens that black-mailers will systematically weave a web whereby they may entangle a wealthy person. The possession of wealth confers no exemption from the weaknesses and frailties of human nature, and in many instances indeed the unwise use of money only brings the obliquities of its possessor into greater prominence. It is not long since an affluent and well-known elderly merchant of this city, walking in the neighborhood of the Fifth Avenue Hotel, had his attention attracted by a beautiful woman of graceful carriage and voluptuous symmetry of form, who seemed to keep just abreast of him on the inner sidewalk, and maintained this relative position block after block. He was not insensible to the charm of the situation, and, before he exactly knew how, was engaged in conversation with the fair unknown. She was an admirable conversationalist and spoke with that expressive pantomime which gives probability to the blackest lies. Thus conversing, he accompanied her to the residence she had been describing. The "residence" proved to be an assignation house. He entered, unconscious of the character of the house, and, as he had been on his way home, remained within only a few brief moments. Bidding the lady politely "good-day," he took his leave. As he walked rather briskly up the street he was accosted by a gentleman, who brusquely said: "So, sir! I have got you at last. I have had my suspicions excited for some time past concerning the probity of my wife, but until to-day have failed in discovering proofs of her infidelity. Now, however, I have them! You have just left the house. I saw you and her meet on the street and I followed you."
