I need to write a short story about a mysterious old house. The story should be at least 150 words long and contain at least 3 paragraphs separated by markdown dividers: ***. The response must have a title, wrapped in double angular brackets, such as <<Mystery at the Old House>>. The story should include the keywords: [creaky floorboards], [whispering wind], [flickering candle], and [hidden diary]. The story should end with the phrase "What secrets does the house still hold?"
