Now, Kikuyu mythology and folklore often include proverbs, riddles, and oral traditions. These stories might be used as enigmas, where the solution or deeper meaning isn't immediately apparent. However, I should recall if there's an existing collection that combines both enigmas and Kikuyu elements in PDF form. From my knowledge, such documents might not be widely known. Academic institutions or cultural preservation groups might have resources, but they might not be readily available as PDFs with a "verified" status.

I should also check if there's a specific work or author associated with "ndai na gicandi". A quick search (as per my data up to 2023) doesn't bring up a direct match. It's possible that the term is a mistranslation or a misspelling. If it's a local or regional term, local directories or community websites might have the content, but those are not globally accessible PDFs. The user might need to consult local libraries or cultural organizations in Kenya.

Another angle: The user might be looking for educational materials or culturally relevant content for personal or educational use. They might need these for research, teaching, or preserving cultural heritage. If that's the case, offering sources on Kikuyu folklore that are published and accessible would be helpful. But I need to be cautious not to provide outdated or unverified information.

In summary, the user is likely seeking authentic Kikuyu enigmatic stories or riddles in a PDF format, possibly mistranslated. I should outline potential sources, advise on verification methods, and note common sources of such material. Also, clarify possible misunderstandings in the terms used and suggest alternative resources if direct matches aren't found.
