民间故事中的最吸人谜题：小岛的诡计

段五郎接到了研究所所长小岛博士的紧急电话，告知他刚收到一个威胁电话，要求交出一份绝密文件，不然就要他的命。面对这种情况，小岛博士无能为力，只好求助于段五郎，请他晚上8点准时来到他家，以便详细谈谈情况。

夜幕降临，段五郎按响了门铃，但屋内竟无回应。他见房里灯光依旧亮着，便不经意地转动了把手——门竟然是开着的。 Segment Five rushed into the room, only to find Dr. Kojima unconscious on the sofa, with a handkerchief emitting a strong medicinal scent nearby.

Dr. Kojima slowly opened his eyes, instinctively reaching for his pocket and exclaiming in despair: "It's gone! The confidential documents have been stolen!" Segment Five was shocked and asked who could have done it and when. Dr. Kojima glanced at his watch and replied that it must have happened about 30 minutes ago while he was watching TV and eating an apple.

However, as they investigated further, they discovered that the apple core had not yet turned brown despite being left out for half an hour. This discrepancy sparked Segment Five's curiosity, leading him to suspect that Dr. Kojima might be behind the theft himself.

Segment Five calmly took a look at the television set under which another apple remained uneaten before turning off its power supply. He then pointed at Dr. Kojima with a stern expression: "You sold them out yourself."

Dr. Kojima was taken aback by this accusation but tried to maintain his innocence until Segment Five revealed that he had found something else in the living room—a large bag of cash hidden inside an icebox.
