Final answer:
In 'Dr. Jekyll and Mr. Hyde', Enfield recounts a strange incident at Black Mail House involving Mr. Hyde, who trampled a young girl and compensated with a cheque from a respectable person, adding a sense of secrecy and evil to the place.
Step-by-step explanation:
In chapter one of Dr. Jekyll and Mr. Hyde, Enfield associates a strange occurrence with Black Mail House. He tells a troubling story about an incident he witnessed. A man, later identified as Mr. Hyde, violently trampled upon a young girl in the street, then went nonchalantly into the Black Mail House. When the crowd who witnessed demanded reparation for the girl, Hyde retrieved a cheque signed by a well-respected man (implied to be Dr. Jekyll) from this house. Enfield found it confusing and eerie, thus associating a sense of foreboding secrecy and evil with Black Mail House.
