Why is the book in oilskin packet Treasure Island?

The book in the oilskin packet in Treasure Island is not Treasure Island itself. It's a map, specifically a treasure map that leads to Captain Flint's buried riches.

Here's why it's important:

* The Map's Importance: The map is the driving force behind the entire story. It's what sets the characters on their quest, fuels their greed, and causes conflict.

* Symbolism: The oilskin packet represents the allure and danger of the treasure. Oilskin is a tough, weatherproof material, suggesting the map's durability and the treasure's enduring power.

* Mysterious Origins: The map's origins are shrouded in mystery, adding to the suspense and intrigue. It's a relic from a dangerous past, hinting at the perils that lie ahead.

The book "Treasure Island" itself doesn't have a map as a physical object within the narrative. The story focuses on the journey and the characters' interactions as they seek to find the treasure.
