Only One Left

The person who was responsible for to check the ship that has been docked at the port noticed something unusual. He was holding the pad that had a chart filled with information about the ships. He was confused because this one ship was nowhere in the chart. Even he had no idea when this ship was docked here as the information that could tell him about it wasn’t with him. Afraid that he might lose his job he didn’t say anything to his seniors but eventually he did because this was a matter of national security.
