Griffin, once a brilliant scientist, had worked hard to discover that human body could become transparent and invisible. He didn't utilise this great discovery for the welfare of the society but only for his petty crimes, thefts and burglaries. He became a lawless man hitting, beating and robbing innocent people. But invisibility helped him in escaping when there was a danger of his being caught and arrested.
The first time when his invisibility helped Griffin was when he lay asleep fully dressed on a pile of quilts. In a big London store, when the employees saw him, he panicked. When he was chased, he threw away all his clothes and saved himself after being invisible. The second time Griffin's invisibility helped him was when he burgled a clergyman's house. He decamped with all the money that was in the clergyman's desk. The invisible Griffin created a scene when he hit Mrs. Hall with a hat into her face and pushed both of them out by using a chair. This led Mrs. Hall to think that her house was haunted by spirits. In revenge, Griffin had set the house of his landlord in London on fire. He had to throw off all his clothes to become invisible and save himself. Finally, when the village constable Jaffers came to arrest him, he made him unconscious and hit all those who came to his help. Nobody knew how to face an invisible man.
But invisibility was also a curse for him. He had to be without clothes to become invisible. And to be without clothes in the chill weather was very challenging and dangerous. Invisibility made him a lawless and homeless wanderer, without clothes and without money.
