A Japanese ship was en route in the open sea. The Japanese captain went for a shower removing his diamond ring and Rolex watch on the table. When he returned, his valuables were missing. The captain immediately called the five suspected crew members and asked each one where and what he was doing for the last 15 minutes. The Filipino cook in a heavy overcoat said, “I was in fridge room getting meat for cooking.” The Indian Engineer with a torch in hand said, “I was working on generator engine.” The Sri Lankan seaman said, “I was on the mast (top of the ship) correcting the flag which was upside down by mistake.” The British radio officer said, “I was messaging to company that we are reaching the next port in 72 hours. From now that is Wednesday morning at 10 AM. The British navigation officer said, “I am on night watch, so sleeping in my cabin.” The captain caught the liar. So who is the thief?
