Question -
Answer -
The invisible man, Griffin first became visible when he stepped in some mud and his footprints were all over the steps of a house in the middle of London. His footprints were noticed by two boys who followed, fascinated, until the muddy impressions became fainter and fainter and at last disappeared altogether. He escaped easily enough from the boys who followed his footprints in London. As it was mid-winter, he slipped into a big London store for keeping himself warm and slept there while picking up a pair of shoes, an overcoat and a wide-brimmed hat from the store. When he wore the clothes, it made him visible to the shop assistants when the shop opened in the morning. Thereafter, he had to shed all his clothes to escape from them and became invisible again.
