Step-by-step explanation:
The writer who wrote Treasure Island, A Child's Garden of Verse, and Strange Case of Dr Jekyll and Mr Hyde is Robert Louis Stevenson. Stevenson was a prominent Scottish author who contributed significantly to children's literature in the Victorian age.
His works combine elements of adventure, mystery, and morality, often drawing from his own life experiences and the broader Victorian society's preoccupations.
Stevenson's Treasure Island has become a classic of pirate adventure, captivating readers with its tale of buccaneers and buried gold. On the other hand, A Child's Garden of Verses is a collection of poetry for children that explores childhood imagination and play.
