Grover tracks the pages to a character in mysteries written by Maureen Townsend in the 1920s. HPD hasn't been able to find Endo. Steve asked Adam to search for him. The pages came from an unpublished novel. Suzanne Ridge, a Townsend expert, secured the publishing rights to that manuscript and plans to unveil it at the literary festival. According to Ridge, there should be two more murders. McGarrett finds a transmitter inside Ridge's pen. So the killer could download the manuscript. Harry's literary double, Gabe, is abducted.

Noelani calls about Joel Butler, poisoned with arsenic. Ridge is the final target. Adam visits a secret camera in the forest. Harry walks in and transfers the $10 million. Suzanne is almost drowned in her bathtub. Harry had an agent intercept the ransom payment, but she steals the money instead, because he failed to call her back when they were dating.

The team and Harry watch fireworks from Harry's balcony. Adam's camera caught Kenji killing Endo and Haru. Four masked men approach Adam's building.
