I made a few more changes. Let's hope everything is fine this time. Thank you.

1) Mr Utterson decides to look for Mr.Hyde. At last, Mr. Hyde appears. Utterson hears his steps approaching the end of the street.
2) He is a small, plainly dressed man and his appearance shocks him. When Hyde rounds the corner, Utterson steps up and, just as Hyde is inserting his key, Utterson touches him on the shoulder and asks, "Mr. Hyde, I think?"
3) Hyde shrinks back with a "hissing intake of breath". He seems frightened but his fear is only momentary.
4) He soon collects his cool veneer: "That is my name. What do you want?" Utterson introduces himself as an old friend of Henry Jekyll.
5) Hyde, keeping his head down, returns his greetings and then he coldly tells him that Jekyll is away. Utterson asks Hyde to show him his face, so that he will know him if he sees him again.
6) The man hesitates for a moment before defiantly revealing his face. 7) The man gives Mr. Utterson his address in Soho and asks how Mr. Utterson got his name.
8) The lawyer suspects of the Hyde’s possible knowledge of Jekyll’s will. Then he replies that he got it from Dr. Jekyll.
9) Hyde accuses Mr. Utterson of lying and promptly disappears through the door. The lawyer is stunned by Hyde's behavior.
10) He believes Hyde’s personality is a sort of ”murderous mixture of timidity and boldness." Utterson realizes that until now he has never felt such loathing; the man seemed "hardly human."
11) Something disgusting characterized his body. He fears for the life of his old friend Dr. Jekyll because he feels sure that he has read "Satan's signature on the face of Edward Hyde."

8) The lawyer suspects of the Hyde’s possible knowledge = drop "of the" = The lawyer suspects Hyde's possible knowledge.....

A question about your English. First I saw: 3) Hyde shrinks back with a "hissing intake of breath". = with the period outside the "quotes" I suspected British English. then I saw: 10) He believes Hyde’s personality is a sort of ”murderous mixture of timidity and boldness." Utterson realizes that until now he has never felt such loathing; the man seemed "hardly human." = now I thought "American English?" (because the periods were inside the "quotes" yet not part of the quote.

Are you preferring British English or American English for punctuation? Unless some statements are from a British person and some from an American person, shouldn't they be consistent?

Likewise the end punctuation in #11.

In this passage, Mr. Utterson decides to actively search for Mr. Hyde. He waits until Hyde appears, and as he hears his steps approaching, Utterson steps up to him and touches him on the shoulder, asking if he is Mr. Hyde. Hyde initially appears frightened but quickly regains his composure. Utterson introduces himself as an old friend of Henry Jekyll and asks to see Hyde's face so he can recognize him in the future. After a moment of hesitation, Hyde reveals his face and gives Utterson his address. Utterson suspects that Hyde may have knowledge of Jekyll's will and mentions that he obtained Hyde's name from Dr. Jekyll. Hyde accuses Utterson of lying and promptly disappears through a door, leaving Utterson stunned by his behavior. Utterson realizes that he feels a deep loathing for Hyde, describing him as a "murderous mixture of timidity and boldness" who seems hardly human. He becomes fearful for Jekyll's safety, believing that he has seen the mark of evil on Hyde's face.
