He seems frankly sceptical, but the thought of all the possible treasure finally convinces him that it is worth having a look.
The two of you follow the ghost's directions to the pig barn. The directions were quite accurate and easy to follow, so you manage to find it without much trouble.
Taking care to be sure you aren't observed by anyone, you sneak inside and look around for the chest.
You find it without too much trouble. The ghost's skeleton is indeed on the top of the pile, nothing left but the bones and clothes that he wore.
You put the bones carefully in a bag, and each scoop out as much of the gold coins and jewels as you can carry.
The two of you find a nice, quiet place to bury the skeleton, and then lug your treasure back to the inn.
You stay on for a few more weeks, while trying to decide what to do now that you're rich. The ghost stops haunting the inn, and Kershaw is delighted.
You like Gerriton, and decide to stay.
Your appetite for adventure has just been whetted by
finding this treasure.
You bank your money
and head for the castle ruins
