4. Japanese Ship Riddle

A Japanese ship was sailing on the open sea. The Japanese captain went for a shower but before doing so, removed his gold ring and set it on the table. However, when he returned 20 minutes later, his gold ring was missing. The captain immediately called five of his crew members he suspected stole the ring and asked each one what they were doing in the last 20 minutes. The Filipino cook said, “I was in the kitchen preparing food for the crew.” The Indian engineer with a torch in his hand said, “I was working on the generator engine.” The Sri Lankan seaman said, “I was on the mast of the ship correcting the flag which was upside down by mistake.” The British radio officer said, “I was messaging that we are reaching the next port in approximately 48 hours. From now, that is Friday morning at 9am.” The British navigation officer said, “I am on night watch, so I was sleeping in my cabin.” The captain worked out who stole the ring with a simple case of detective work. So, who stole the ring?


Answer: The Sri Lankan seaman stole the ring. They are travelling on a Japanese ship which would bear a Japanese flag. The Japanese flag would look the same if it was turned upside down so the Sri Lankan seaman must have been lying.

2. The Murder of Mr. Tony

Mr. Tony is a very rich man and he lives in a mansion. He has a maid, a butler, a cook and even a lifeguard. This morning, Mr. Tony was found murdered. A detective was called from Sunday church to investigate the murder and met up with police who were already at the scene. Six suspects were interrogated: the maid, the butler, the cook, the lifeguard, the postman and Mrs. Tony. The maid said that she was cleaning the house. The butler said that he was playing chess with Mr. Tony’s son. The cook said that he was preparing breakfast. The lifeguard said that he was watching Mr. Tony’s daughter swim in the pool. The postman said he was delivering mail and Mrs. Tony said that she was sleeping. The detective figures out that somebody is lying and that person is likely to be the killer. Who is lying? You only have one chance because if you accuse the wrong person, the killer will escape so make it count.


Answer: The postman was lying. The detective came from church on a Sunday to investigate and you should know that the post office does not deliver mail on a Sunday, meaning the postman can’t have been delivering mail but instead murdering Mr. Tony.

A man murders his wife in cold blood with a knife in their car. There are no witnesses. He throws her body out the car, taking care not to leave any fingerprints and also throws the knife off a cliff where it will never be found and then he goes home.

As soon as the man arrives, he is arrested. How did the detective know that the man did it?


Answer: The man never asked the detective where the scene of the crime was, so the detective instantly knew that the man had, in fact, murdered his wife.
