You figure that the treasure may make the boat too heavy. So you climb in and pull the lever.

The boat tips forward. You careen down a rock slide, the light from your phone illuminating the blur of rocky walls whizzing past. The boat pitches and trembles as it knocks against the walls. As you hold on for dear life, you drop your phone. It gets thrown from the boat and smashed to pieces against the wall. You are hurtling through darkness on a nightmare rollercoaster ride.

And then the boat slows down and comes to a stop. There is a faint glow coming from the distance. You climb out of the boat and walk forward. There is a precipice ahead of you. You look down to see an underground river leading to the mouth of a cave. You have no option – you take a deep breath and dive in.

Splash!

You start swimming. Once you are out in the open, you look around to see the cove. Soon you are on the sand with your mum and dad, telling them about One-Eyed William and the treasure.

You go to the museum and tell the curator. A search party is sent to check out your story … and the treasure is found!

Go here.
