Question

The unveiling of the stranger was as unplanned and sudden for himself as for the people of Iping.
Explain the reason, incident and consequence of his unveiling. refer the novel class 12 "The Invisibe Man"

Answer 1

The stranger remains locked in the parlor all morning. He rings his bell for Mrs. Hall several times, but she does not answer it. About noon, he emerges and demands to know why his meals have not been brought to him. Mrs. Hall tells him that his bill has not been paid in five days. She refuses to accept the excuse that he is waiting for a remittance. When he produces some money, she refuses it, saying she first wants to know why he doesn’t enter by doorways and move about like normal people.

For his answer, the stranger removes all his head wrappings, including his nose and moustache. He thus looks like a person with a missing head. At the sound of screams a crowd of people run toward the inn. “Eye-witnesses” suddenly babble hysterical stories of the man attacking the servant girl, and brandishing a knife. Bobby Jaffers, the village constable, appears with a warrant.

The stranger slaps Jaffers with his glove, but then says he will surrender. He will not accept handcuffs, however. As the constable, Halls and others watch, the man removes the rest of his clothes, becoming invisible before them. He tells them that he is invisible. Jaffers wants to take him in for questioning on suspicion of robbing the Bunting home. A scuffle ensues, and the stranger, now known as the “Invisible Man,” escapes.

Answer 2

It is quite true the unveiling of the stranger was unplanned and sudden for everyone; neither had he planned to make his invisibility known to people in Iping, nor people had ever expected they would see such a phenomenon in their village.  

The reason behind this unveiling was Griffin’s short temper. He had been annoyed and irritated to the extreme limit by Mrs. Hall. She had been pestering him to clear his arrears. However, he had no money; so he planned a robbery at the vicarage. When he was robbing the Buntings, Mrs. Hall and Mr. Hall found an opportunity to go into his room, which they found ajar. As they were examining the room and its contents in surprise, Griffin came back; he lost his temper and scared the Halls out of his room by lifting the chair; this not only scared them to their death, but also convinced them Griffin was dangerously mysterious and had connection with the supernatural world.  

Mrs. Hall decided to expel Griffin out of her hotel; so she did not serve him any meals. This further infuriated the short-tempered scientist. When he went to the bar to ask Mrs. Hall why she had not answered his calls, Mrs. Hall put many questions to him regarding the strange happenings she had seen in his room.

At this point, Griffin burst out; in sheer anger, he revealed his invisibility himself. Just to show the owner, he took off his artificial nose and put on her hand. Later on he showed his entire invisibility.
