Ep. 28: Inspektur Kenmochi menyelidiki hilangnya seseorang secara misterius di atas kapal kargo yang menuju Okinawa.

Inspector Kenmochi takes Hajime and Myuki on the Cobalt Marine, not a cruise ship, but a cargo freighter with accommodation to Okinawa. Meanwhile, Captain Kozo Takamori has received a letter from a Ghost Captain stating that the cruise of death has begun. Takamori asserts that it was sent by one of the disgruntled crew and accuses the Navigator Mikihiko Wakaouji. When Hajime is ill the next morning he discovers that Second Mate Joji Mizuzaki and female crew member Yoko Katori are romantically involved. Also, Captain Takamori appears to have disappeared although when they enter his locked room it appears that he was just eating breakfast. A passenger and reporter for a ship magazine Yoshikazu Akai suggests it is just like on the Mary Celeste. The crew then discover the communications equipment has been destroyed. Hajime calculates the time that the person responsible for the captain's disappearance left his room and checks everyone's alibis but the results are inconclusive. (Source: Wikipedia)
