A Japanese ship was leaving the port and on its way to the open sea.
The captain went to go oil some parts of the ship and took his ring off so it wouldn’t get damaged.
He left it on the table next to his bunk.
When he returned, it was missing.
He had suspected three crew members could be guilty and asked them what they had been doing for the ten minutes that he had been gone.
The cook said, “I was in the kitchen preparing tonight’s dinner.”
The engineer said, “I was working in the engine room making sure everything was running smoothly.”
The seaman said, “I was on the mast correcting the flag because someone had attached it upside down by mistake.”
The captain immediately knew who it was. How?
