Chapter five:

Excitedly, Dr. Livesy opens the packet with his medical scissors and discovers a book and a sealed piece of paper. The book appears to be an accounting of the loot of the treasure, complete with the exact amounts plundered and where he gained these. The piece of paper was a map of an island with words "bulk of treasure here." In the same handwriting, on the back of the map, was information regarding coordinates and how to get the treasure.
